How Far Will An FM Transmitter Broadcast ?

Some customers often ask us for some professional radio equipment knowledge, such as “How to build a complete radio station at low cost?”, or “How to choose dipole antenna for my high power FM transmitter? 6-bay dipole antenna or 8 bays?", etc. The interesting thing is, they are much more curious about the range of an FM radio transmitter and have raised so many related questions to our RF engineers. And the following content is part of the frequently asked questions list on FM transmitter range and the corresponding share. We hopefully believe this share on transmitter coverage can help you solve your problems, whether you are one of our customers or not


Common questions asked from our customers:

How far can a 1-watt radio transmit?

How far will a 1 watt FM transmitter reach?

How far will a 5-watt FM transmitter go?

What is the 15w FM transmitter range?

How far will a 15w FM transmitter broadcast?

What is the kilometer range of a 15W FM transmitter

What is the FM transmitter range chart?

How far will a 100 watt FM transmitter reach?

How far will a 5000 watt FM transmitter reach?

How far can a 50000 watt FM radio station reach?

How to calculate the FM transmitter range/FM transmitter range calculator?


Interesting thing is, when our customers want to know the coverage of our radio broadcast transmitter, we will always state in advance: "You cannot have the accurate number of the coverage range of an FM broadcast transmitter (regardless of power or type), unless you are in the laboratory! "The reason why we can explain this to our customers is that according to the observation of our RF expert team, there is more than one factor affecting the broadcast coverage of the transmitter. Effective radial power (ERP) and the antenna site height above average terrain (HAAT), and many other variables are also important factors we need to consider.


Therefore, in order to satisfy our customers with actual answers and help solve practical problems, our RF engineers and sales team usually give some specific numbers. For example, for customers who ask about the coverage of low-power transmitters, we usually say: "15W FM transmitter can cover up to 3k㎡, while 25W FM transmitter can cover up to 5k㎡. If you want to cover a wider range, such as 10k㎡ or 20k㎡, you should choose a 150W or 350W FM broadcast transmitter because they are larger in transmitting power"


However, for some radio newbies, these accurate figures may cause unnecessary misunderstandings and push them into thinking factors that will affect the coverage of an FM radio transmitter. Although the corresponding answers are hard-won, we still summarize the following factors that can determine the coverage (which means how far they can go) of an FM transmitter:



1. The broadcast transmitter output power amount (TPO)

TPO is abbreviated from “Transmitter Power Output” in the field of wireless communication, it actually refers to the outputting power produced by a transmitter, if you were told that "This is our top-sales 5kW FM transmitter", then this "5kW" is always seen as the ERP power (Effective Radiated Power) instead of the actual transmitter power. TOP is closely connected with cost, buying, budget, etc., which is mainly because a wider ideal coverage comes with a higher buying price for some of the radio station equipment such as an FM broadcast transmitter and FM radio antennas. Therefore, TOP, together with antenna gain, are two of the most important factors that should be taken into consideration especially in the early period of radio station buildup, when you're deciding which brands and what equipment is best for your budget.


2. The Antenna placing height above average terrain (HAAT)

In radio broadcasting, HAAT or EHAAT(effective HAAT), or height above average terrain actually refers to a vertically comparable distance between a transmitting site(transmitter and antenna are included) and the average terrain height among few kilometers. To reach a common understanding of the HAAT key points, one needs to know that HAAT is basically the coverage of a broadcast antenna, it is the vertical position of an antenna site is above the surrounding landscape. Suppose you are standing at a position flush with the installation site of the antenna, at this time, you and the transmitting site are on a plain, then the antenna may reach a tens of kilometers distance for broadcast. If your position is not a plain but a hilly area, the broadcast distance may reach only several of kilometers. HAAT is officially measured in meters, which is widely recognized by international coordination, and of course by regional radio organizations such as the Federal Communications Commission (FCC).


This also reminds us that if you want to obtain the maximum coverage when the transmitter, receiver, antenna, and accessories are ready, always remember to place the antenna as high as possible, so as to obtain at least 60% clearance in the Fresnel area and get real RF line of sight (LOS), plus, it helps avoid the negative factors to stop the RF range from expanding, such as the dense trees and high buildings, etc.



1) Due to the lower antenna height, the loss in the RF cable is smaller, and the antenna may work in a better condition at this time, so think of the trade-off between the antenna height and the number of RF cables required.


2) After the assembly of hardware broadcasting equipment, please be sure to pay attention to the local radio administration's regulations on antenna height to prevent penalties (in some areas, the penalties for the inappropriate antenna height are quite heavy).

Guidances For Fresnel Zone
Tips Definition to Fresnel Zone in Radio Frequency
Application Physical area
How it generates the transmitter and receiver are at the line of sight
What it belongs:  radio wave
What does it mean? The Fresnel region is between the transmitting and receiving antennas, and the travel difference between the straight path and the broken path of the radio wave is n λ/ 2 is an ellipsoid with the position of the transmitting and receiving antenna as the focus and the straight path as the axis. The size of the ellipse is determined by the operating frequency and the distance between the two stations. In the field of wireless communication, to ensure the best working conditions for the whole system, one thing that matters is keeping a clear elliptical passing area between different antennas on both broadcast sites, making sure there are no limits, no stoppages, no obstructions for the processing.
Why it is important Because any interference or obstacle in line of sight (LOS) may cause signal loss, in point-to-point wireless communication, it is important to keep the line of sight between two wireless systems free of any obstacle

3. Types of antenna and accessories that used in the antenna system types of antenna and coaxial cable used amount of coaxial cable used


4. The sensitivity of the FM receiver at the other side


Irreversible factors

1. The degree of emptiness in the terrain around the antenna site encumbrance that surrounds the antenna site, such as the density and height of trees or buildings 

2. Type of terrain near the antenna site flat or hilly

3. Radiofrequency interference due to same frequency broadcasting from near radio station


The near frequency stations or other radio stations broadcasting in the same frequency, for example, the antenna may be able to see 20 kilometers, but if another station is on the same frequency 20 kilometers away, it will block/interfere with the signal.


The truth is: you can never determine the exact coverage of a broadcast transmitter no matter the transmission power or brands it belongs to. Fortunately, you can always obtain the estimated coverage of some radio broadcast transmitters from the RF experts (just as we did earlier).


These estimated numbers do goods in actual practice-to help you think twice before choosing a good broadcast transmitter and reduce unnecessary costs or expenses, or be well-referenced in after-sales services or any online technical support after buying an FM transmitter.


Of course, we all know that experience is the best teacher. To set up an FM transmitter and run it directly may be the best way to obtain the most accurate coverage of an FM radio transmitter.


FMUSER hereby suggests that you can try to use different variables and conduct multiple experimental comparisons, for example, you can:


1. Determine the type of antenna (4-bay or 2 bays FM antenna is great)

2. Determine the wielding height of the antenna (30 meters is pretty enough, that equals to a 15 story building)

3. Determine the power of the radio transmitter (you can also change 200 Watts to 500 Watts, and vice versa).

4. Find different sites as the transmitting point (consider whether you are in a flat or hilly area or right on a mountain)

5. Record the farthest broadcast distance you can receive clear radio signals from the transmitting point

6. Change the variables and make comparisons to what you record.

If you find that there is nothing you need in the transmitter coverage reference table provided by us, please let us know the first time. FMUSER can help you estimate the coverage of your radio transmitter.

How To Maintain Radio Station Equipment | Ultimate Tips for Radio Personnel l

How to maintain those expensive broadcast equipment in an FM radio station? For the radio broadcasting stationmaster, any damage to the equipment means extra maintenance cost needs to be paid. So, in order to keep the sustainable and healthy development and of course to lower your cost, one must have those equipment maintained/checked weekly, quarterly, or annually for a broadcast station.


By listing practical refering information such as basic equipment working principles and standards, this share can provide extensively useful maintenance experience and precautions for the FM radio station maintenance, including the FM transmission system equipment and FM radio studio equipment.


This share is also a great maintenance guide used to prevent any damage to broadcasting equipment caused by equipment aging and improper operation, etc. and provides the measures to be taken before and after the establishment of some broadcasting stations, which can be used as a reference for the stationmaster to make decisions of fault diagnosis in advance.


Do know that due to the different RF transmission equipment at each broadcast site, the maintenance methods may need to be adjusted to actual conditions and this share is for reference only.


Building an FM Radio Station is NOT Easy

Most LPFM radio stations generally are facing insufficient start-up budgets at the initial stage of construction especially In most developing countries. Although the station owner may go buy some necessary audio inputting or processing equipment with these budgets, it still meets no requirements to the basic broadcasting needs.


Mostly because of Cost

World-famous radio station equipment supplier such as BSW provides equipment with extraordinary broadcasting quality, but the price is also very unfriendly for the budget buyer, directly it leads the way to many stations driving their attention to focus more on internal operating costs (such as utilities and labor costs) and external activity costs (generally marketing activities) than the equipment cost.


However, a buying plan for radio station equipment will still be an important part of the professionalization of radio stations in the next few years. When start-up funds are needed, these radio stations often seek donations and sponsorship (generally sponsors) to start a basic LPFM radio station.


Common Maintenance Checklist

If you are too busy to read those lengthy manuals or need key maintaining information only, well, can't be bad to take a few minutes to quickly browse the following radio maintenance summary and tips :


Must know items

Read the operating instructions carefully to ensure that you can operate the equipment completely and safely, and store the operating instructions uniformly for future reference.


In case of any difficulties occurs in overhauling the equipment, please operate properly under the instructions or hand it over to the maintenance engineer, or consult the station equipment manufacturers


If your radio station equipment encounters any of the following situations, please pull out the plug or turn off the main electricity switch in advance and contact maintenance engineer personnel in time

If the device made any different noises, or suddenly stop working, or has uncommon instructional light flashings or else that goes against its normal working condition.

If the device is get damaged in either of the circumstances: dropping, damping, burning, exploding, corrosion, rust, or any other force majeure.

If the device is dropped or damaged in any way.

If the device exhibits significant performance changes

If the equipment is exposed to rain or water.


Line Connection

Power supply – Before purchasing any electrical appliance (including all types of broadcasting equipment), please identify its voltage, power supply type, and other parameter information related to the "electricity" in advance. When you buy some radio equipment suppliers from other countries, different products need different voltages because different countries use different power transmission systems. This may lead to different types of power supplies and power ports (you can often see some words such as 220V on the backboard of an FM transmitter).


If you can't distinguish in time or don't know how to distinguish after ordering, you'd better contact the equipment supplier for product replacement or return service. You can also carefully read the relevant contents in the product manual to ensure that you take the initiative in after-sales service communication.


Power cord protection - the power cord shall be routed so that it will not be trampled or clamped by objects placed on it or leaning against it. Pay special attention to the wires at plugs and convenience sockets and their positions to exit the equipment.


Power lines – the external antenna system shall not be located near overhead power lines or other lights or power circuits, or where it may fall into such power lines or circuits. When installing an external antenna system, take extra care to avoid touching such power lines or circuits, as touching them may cause your death.


Overload – do not overload wall sockets or extension cords as this can cause fire or electric shock.


Outdoor antenna grounding – if an external antenna or cable system is connected to the equipment, ensure that the antenna or cable system is grounded to provide some protection against voltage surges and accumulation of static charges.


Equipment Processing

Cleaning - Always remember that any extra liquids or cleaners such as aerosol do no good for the cleaning of the appliance, but a soft cleaning cloth with a bit damp sounds better!


Accessories - do not use accessories that are not recommended by the equipment manufacturer because they can be dangerous.


Handle the equipment with care. Rough handling, quick stops, excessive force, and moving on uneven surfaces may cause equipment to fall or damage.


Ventilation - Always leave proper air passing space for the radio equipment to avoid overheating, this means DO NOT leave your station equipment in some tiny and blocked areas, and leave those air vents wide open instead of closely placing them in front of some hard surfaces such as a wall or a bed. And also need to know about: do make any adjustment to the equipment only when you're a maintenance engineer, or the equipment might break down easily due to improper operation.


Replacement parts – When replacement parts are required, ensure that the service technician uses the replacement parts specified by the manufacturer or those with the same characteristics as the original parts. The unauthorized replacement may cause fire, electric shock, or other hazards.



Water and moisture - do not use equipment near water - for example, near a bathtub, washbasin, kitchen sink or washing basin; In the damp basement; Or close to the swimming pool or any similar wet or humid place.


Stability - do not place equipment on unstable surfaces. The equipment may fall, cause serious injury to yourself or others, and cause serious damage to the equipment. It is best to install all broadcasting equipment on the rack or bracket recommended by the supplier or sell it with the equipment.


Lightning - to provide additional protection for your equipment during thunderstorms, or when it is left unattended and unused for a long time, unplug it from the wall socket and disconnect any antenna or cable system. This will prevent damage to the equipment caused by lightning and power line surge.


Objects and liquids – do not push any type of objects into the equipment through the opening, as they may come into contact with dangerous voltage points or short-circuit parts, resulting in equipment damage, fire, or electric shock. Plus, take care of your radio equipment, and let no other things be placed on top of the equipment or other non-related materials such as water or other liquids to be applied on the surface of the equipment, they are not pressure-resistance or waterproof.


Safety inspection – after completing any service or repair of the product, ask the service technician to conduct a safety inspection to determine whether the equipment is in normal operation.


Wall or ceiling mounting - equipment can only be installed on walls or ceilings in accordance with the manufacturer's recommendations.


Heat - the equipment shall be kept away from heat sources, such as radiators, heat regulators, furnaces, or other heat-generating products (including amplifiers)


Maintainance is Needed for Every Radio Station

This may be a common misunderstanding of many radio station operators: broadcasting equipment is too expensive. Maintenance is unnecessary for it may cause damage to the equipment. However, is this really the case? The fact is: the more expensive and sophisticated broadcasting equipment, the more periodic inspection and maintenance should be carried out.


Regular maintenance can also extend the maximum service life of the equipment in your station because the buying cost for some broadcasting equipment is quite amazing, reasonable maintenance can ensure that the radio station does not need to frequently change that expensive broadcasting equipment, which helps the radio station save a huge expense for replacing the same new broadcast equipment. For some newly established LPFM radio stations, if a longer product service life or higher quality audio signals transmission for the broadcast equipment is wanted, then it will be quite essential to have periodic maintenance of radio station equipment.


The most important thing is that, whether it is a new station or an old station, regular maintenance for equipment and transmitting site can help maintenance engineers predict some fatal problems that may affect the broadcast station in advance, and make timely remedial measures to prevent problems before they occur. This can ensure that, for example, when your radio transmitter suddenly burns out due to negligence of maintenance or the aging of the components, which causes the radio program to stop playing, your radio program listeners may be complaining and then switching to other programs on different radio frequency and evitably leaves with a bad radio experience - this may be more terrible than the lack of start-up funds!


Always pay attention that improper operation, maintenance, and repair may directly lead to the damage of broadcasting equipment and even endanger the life safety of equipment maintenance personnel.


Therefore, for most newly-established radio stations, in addition to periodic inspection and maintenance of broadcasting equipment, necessary maintenance training shall also be provided for personnel to acquire necessary maintenance knowledge and skills, and always asked to correctly use the maintenance tools so that they can carry out the overall continuous maintenance work of the radio station in weekly, monthly, quarterly or annually.

How To Maintain The FM Transmitting Site ?

Self-inspection items regulated by FCC:

1. General items: tower lamp and tower paint inspection

2. Monthly items: safety check for the tower fence, make sure it is secure and locked

3. Quarterly items: frequency check of all exciters, STL receivers, TSL transmitters, and logs.

4. Annually items: accuracy check for all licenses and authorizations, to ensure that all licenses are updated and ready-steady for being checked


General maintenance as required:

1. Replace the electronic parts of the main / standby broadcasting equipment, such as an electronic tube, etc

2. Use the spectrum analyzer to check whether the harmonic has proper attenuation, and scan the antenna and transmission line to ensure that it is on the frequency and has sufficient bandwidth to transmit an FM signal

3. Check whether the electric tank and generator work normally. If fuel is used for power generation, check its oil level and refill the oil tank

4. Check whether the paint on the internal and external walls of the site fades or falls, and repair it in time


General maintenance on weekly basis:

1. Record the work log and special data of core broadcast equipment such as broadcast transmitter and STL systems, such as abnormal forward / reflected power of broadcast transmitter or signal strength value of STL system, and make maintenance in time. Don't forget the overload maintenance work, check whether there is any abnormality by resetting any overload


2. Keep the working environment of the equipment dry and tidy, and ensure that there are no serious factors from the outside, such as water leakage from the roof, electricity leakage from the socket, or wind entering the station due to wall damage. Clean up the room in time to provide a good working environment for maintenance personnel


3. Ensure the integrity of the monitoring system. Since the equipment value of the radio room is very high, and it is unrealistic to send personnel to stay in the radio room (especially some small radio rooms), it is necessary to check whether the monitoring system is complete, including power supply system, camera, cable arrangement, etc. if there is any damage, it shall be repaired in time


General maintenance on monthly basis:


1. In addition to completing the maintenance work in weekly units, it is also necessary to add some spare core equipment and complete multimeter logs, for example, connect a spare radio broadcast transmitter with a dummy load, so as to avoid radio dead air.


2. Check the infrastructure inside the machine room, such as pipeline, oil tank, water tank, smoke alarm, generator, etc., to ensure the normal operation of these infrastructures, and avoid the burst due to excessive internal pressure, which might be resulting in some pipeline leakage, oil leakage of the generator oil tank and other accidents


3. Check whether the surrounding of the broadcasting station is open enough, especially in the summer when plants grow wildly. In order to obtain a wider coverage of the broadcasting antenna, it is necessary to ensure that the surrounding spaces are open enough. If necessary, cut down those tall vegetations


4. Check whether the fence of the broadcasting tower and the ground on the tower are firm enough, and lock the entrance of the tower to ensure that no one can easily enter


5. Calibrate the remote control instrument with the transmitter instrument


General maintenance on a quarterly basis:

In addition to the monthly maintenance work, some unnoticed infrastructure needs to be maintained in time, especially for important broadcasting equipment, such as FM exciter and STL system, meanwhile, air filter, tower lamp, and paint inspection, etc. are also maintenance-needed


Maintenance work that must be carried out every year:


1. In addition to completing the maintenance task of quarterly work, it is also necessary to check the licenses and authorizations of all radio rooms to ensure that all business licenses have been updated. When the local radio administration checks the room, you will not be fined

2. Clean the main / standby transmitters, but make sure that one of the transmitters is in working condition. Check whether the generator and related circuits and equipment work normally

3. Conduct a comprehensive inspection of the antenna system, including transmission system, antenna tower, and corresponding infrastructure


Why Do WeNeed to Maintain the Radio Studio?

The broadcasting studio is the place where audio broadcasting programs are recorded and processed, as well as the storage place for much sophisticated audio equipment.


The audio program quality of the broadcasting station depends on the efforts of all personnel in the broadcasting studio. We all know that radio broadcasting cannot be completed by one person. In professional LPFM radio stations, in addition to the maintenance engineers in charge of maintaining equipment, there will be other staff and volunteers who will jointly use the corresponding audio equipment in the broadcasting studio to contribute to the output of complete broadcasting programs of high quality.


However, not every radio station is as much as professional. Some newly established radio stations may recruit inexperienced broadcasting staff due to budget problems, which may lead to some problems in work efficiency and machine use methods. Although work experience can be accumulated step by step, some intentional or unintentional operations may bring damage some sophisticated radio station equipment, and potentially leads to the increase of maintenance costs and even delays the normal broadcasting of radio programs, which is why we mentioned the need for relevant training for equipment maintenance personnel - which is closely related to your equipment maintenance costs and the popularity of radio programs.


In addition to unskilled personnel, the dirty environment of the broadcasting studio, lack of equipment instructions and chaotic studio rules and regulations will also have a huge negative impact on the broadcasting equipment, which will directly or indirectly affect the overall income of the broadcasting station. Therefore, for all personnel of the broadcasting station, Maintaining the radio studio is equivalent to safeguarding its own interests, which is not an easy thing. The radio station master needs to measure the potential impact of some objective factors on the radio station from many angles, so as to plan a better radio station management system, especially related to financial management, such as how to reduce equipment maintenance expenses.


The following content is the maintenance checklist of a radio studio, it is edited based on the feedback of FMUSER's customers who have successfully established radio stations and continue to operate healthily, hoping to help the station owners who have or will build radio stations

How To Maintain The Radio Studio ?

1. Create a good broadcasting working environment for studio personnel

Radio station staff is an important factor to ensure the normal operation of the radio station. Therefore, please provide your subordinates with a high-quality radio working environment and ensure and maintain the construction of infrastructure, which can not only improve the efficiency of radio station staff but also attract more radio station guests and enhance their goodwill for your radio station!

1) Radio Studio Buildup and Design

Many customers will ask FMUSER "What to consider before building a professional radio broadcast station?".

The answer is actually very simple:

Water and Electricity Supply - provides the necessary living conditions for the continuous operation of the radio station, and the stable water and electricity supply makes high-quality radio program broadcasting possible.

Rooms with Different Functions - smoking room, recording room, lounge, bathroom, and even children's toy area can be designed according to your budget

Daily Necessities - water dispensers, paper towels, teapots, coffee machines, and even washing machines, let's make everyone feel at home.

Necessary Furniture - sofas, chairs, radio stations... Provide work and rest areas for guests and staff.

Electrical Appliances - air conditioners, refrigerators, microwave ovens... Meet the daily needs of the radio studio staff.

Studio Lighting - table lamp, chandelier, spotlight... This may affect the line of sight of everyone in the studio.

Studio Decoration - design style, radio layout... Make a good first impression on radio guests

Safety Design - moisture-proof, fire prevention, ventilation... You never want your efforts to be wasted

Special Supplies - medical masks, sterilized alcohol, thermometer... Reduce the risk of covid-19 epidemic! "Take the radio studio as your second home!"


2) Ensure the sanitary conditions of the studio

Under the global epidemic of covid-19, it is necessary to pay much attention to personal prevention and control, especially in some confined spaces such as a radio studio. Therefore, to ensure the sanitary conditions of radio stations, two steps need to be done: Basic sanitary and Epidemic Prevention&Control

Personal Hygiene - disinfection, marking and unified storage of personal belongings, keeping hands clean when handling equipment, keeping a clean and tidy dressing, no spitting, no littering, etc

Studio Hygiene - periodically clean the radio studio, including house pest removal, dust collection, garbage cleaning, desktop cleaning, carpet cleaning, furniture polishing, etc

COVID-19 Prevention&Control - temperature detection for guests, masks always on and not taking off if unnecessary, always remember to use alcohol to disinfect used broadcasting equipment by guests, preparing disposable daily necessities for guests, etc "A clean and tidy studio always makes people feel happy!"


3) Improve the radio studio equipment Management

Product Manuals Copies - To avoid any important maintenance information missing, each kind of radio studio equipment shall have a few copies of main and spare product instructions.

Find Leadership - A special person shall be named and be responsible for safety training for radio staff and unified equipment management

Radio Equipment Guideline - write product manuals or acquire manuals from equipment suppliers for some frequently used broadcasting equipment, or to attach some equipment FAQs that may appear, and post precautions when using the equipment in some conspicuous places to avoid any accidental damage to the radio equipment.

Internal Training - periodically conduct internal training for broadcast studio personnel, explain the use methods and precautions of various studio equipment, and regularly spot-check the training effect

Best Setup Places - you can never know why that broadcasting equipment will be damaged for some reasons, which may be an inadvertent man-made collision or deliberate breaking or twisting of the equipment. Therefore, in addition to internal training and avoiding the use of force on broadcasting equipment, you can also prepare a special place for radio equipment and protect it, for example, find a place where adults can reach the equipment but children can't, or paste some warning stickers for the use of the equipment, so as to reduce the excessive contact between the studio equipment and the third party in the non-working state

Maintenance Fault Reporting - maintenance personnel shall be arranged to report technical problems in time when the equipment in the broadcasting studio go wrong and don't forget the equipment maintenance is technician-only "One shall mind his own business"


2. Material Filing and Archiving

The files of the radio studio equipment are almost as important as the equipment itself, plus, there is a variety of broadcast equipment in the studio, and their respective working standards are different, so the corresponding maintenance methods are also different. You may not have the same complete product knowledge system as your radio equipment supplier, and some detailed information is kept as a business secret and goes unlisted online, therefore, it is almost impossible for you to obtain the same printed info on the manuals by Googling in a short time, especially for some important manuals.Moreover, these materials are parts of your paid goods. Please keep in mind the importance of these materials. If you lose them, you may not be able to obtain the same manual from the equipment supplier for free again. Therefore, remember to file up these "free products"


Organize the Important Equipment Files - the product manual may be one of the most important pieces of radio studio files. It contains all the important information of the corresponding product from the name, model, parameters, maintenance, etc. Some professional radio equipment suppliers will provide complete radio studio turnkey solutions. They will not only design the studio equipment package that best meets your budget for your radio but also provide on-site installation and commissioning of the equipment (if conditions permit) and leave wiring diagrams of each studio equipment. When conducting weekly or monthly equipment maintenance, especially in the maintenance of radio equipment wiring, the wiring diagram can accurately help us locate the fault. In addition, you can also take photos or videos of the equipment installation and commissioning site and record the whole process. When your Engineer has no equipment maintenance clues, these photos and videos can make him flash.


Create aUnique Recording Log - if you are the radio station manager, you are obliged for the stable operation of the radio studio and transmitting system, which means that you need to record the overall radio broadcast process from the start to the end, including broadcast project details, equipment that is used, etc., which contains all your experiences and observations, therefore, this recording log should be unique. The RF and maintenance engineers are responsible for respectively for broadcast field control and equipment maintenance. But not all radio station managers are RF engineers. Therefore, for radio station engineers, a personal record log is also required, but the recorded content may be more inclined to equipment maintenance and solutions.


Homebrew Equipment Manual - this is more like an equipment tutorial. Maintenance personnel can record some key information, and edit and organize it into a product usage tutorial, such as default parameter settings recording of the equipment before power on, or record how to correctly and safely turn on/off the equipment, or to record equipment system backup process, or recording types of equipment that was already applied, etc. The overall equipment working recording provides a more efficient way for maintenance work. It is also a good handbook, which enables a lower training cost and helps you greatly reduce the operation and maintenance cost of the radio station, for the radio newbies, they can understand more about how a radio station works.


Unified Storage for the Filing - of course, the most important thing is to find a place where these important data can be stored uniformly and safely, whether it is the product manual, equipment wiring diagram, or pictures and videos of the installation site, etc. FMUSER highly recommends that to collect all the needed files of each radio studio equipment in time and gather up them in an easy to access, dry and normal temperature place, don't forget to take moisture-proof packaging measures. When equipment maintenance needs to be conducted in time, the maintenance team can respond quickly and obtain the relevant equipment maintenance materials at the first time


3. Make Your Own Best Maintenance Plan

Broadcasting equipment maintenance is different from ordinary product maintenance. Broadcasting equipment is more precise and usually has a higher maintenance cost. Therefore, before conducting any equipment maintenance in the radio studio, you should first consider two key factors: maintenance personnel and maintenance budget


In short, manpower and resources are indispensable factors to be considered in radio station equipment maintenance. They are closely related to each other. Adequate equipment maintenance funds and recruitment budgets can often recruit better equipment maintenance personnel, while other resources, such as detailed equipment maintenance plans, can amplify the role of manpower and funds and help guide the whole process of broadcast equipment maintenance.


It is worth noting that no matter how we pay efforts on detailing our equipment maintenance plans, there will always be unexpected changes that may occur during the actual maintenance.


The following content is some important factors that need to be carefully considered in maintaining radio station equipment:


1) Build Your Radio Team

Even if you can claim that you are a radio station director, RF technician, and equipment maintenance engineer at the same time, but the truth is you have only 24 hours a day, it may take you several hours for the equipment that needs regular maintenance, and that's only a part of radio station daily works, you may also need to take some time recording the equipment feedback - you are likely to miss some key information in this process


So why not try to allocate these tasks to specific personnel? I mean, if you have a radio team... You can coordinate their work, ask them to make a detailed work report, and put forward some suggestions, which may be where you can give full play to your greatest advantage


Tips: Different Broadcast Roles in a Radio Station  

Announcer - The announcers speak for the radio station, they are responsible for radio broadcasting, advertising and service announcements, etc.


Chief engineer -  the chief technician of the radio station, responsible for technical personnel supervision, equipment maintenance and regulation, on-site control of radio, compliance and legal inspection of radio stations, etc.


Maintenance Engineer - similar to the responsibilities of chief engineer, it is specially responsible for equipment maintenance or overhaul of broadcasting equipment after receiving complaints from listeners


Music Director - responsible for handling the radio music library, formulating the radio marketing activity plan, public relations, etc


News director - responsible for maintaining the news sources and program production of radio broadcasting, guiding and supervising the personnel of the news department, etc


On-air personalities - responsible for telling the actual broadcast story. He is the spokesman of the radio station, which is different from the announcer


Production director - responsible for the output of radio programs and some logistics, and supervising the fluency of the process of radio program output


Program director - responsible for the regulation and supervision of the final content of radio programs


Promotions Director - responsible for the external image publicity of the radio station and the formulation of promotional activities


Station Manager - responsible for all daily affairs of the radio station, such as personnel recruitment and training, making radio program broadcasting schedule, managing radio station finance, etc


If you have enough budget for recruitment, you can easily have a group of skilled radio personnel who can be responsible for the daily use and management of your radio station and help you share the complicated radio maintenance work.


You can also take a chance to recruit a certain number of interns or and community radio volunteers respectively. Although this may increase your personnel management burden, it is also a good way to ensure the safe operation of radio equipment, especially when some equipment maintenance personnel are absent from work.


2) Please consider your equipment maintenance cost carefully

As mentioned above, when you have a very professional knowledge system of broadcasting equipment, you can be either the station master of the broadcasting station or the equipment maintenance personnel.


However, most station masters are not necessarily good at radio equipment maintenance as those RF expert engineers do, and the recruitment cost of an expert radio equipment maintenance engineer is very high, so the overall cost of general broadcasting station equipment maintenance is unimaginable


Additionally, when those broadcasting equipment suppliers who can provide you with professional equipment repair and maintenance services are hundreds of kilometers away from you, or even in some places on the other side of the ocean, you will pay several times the cost of ordinary equipment maintenance - because you have to send that maintenance-needed equipment to the supplier across the ocean


Of course, you can also follow their suggestions - to buy or rent new parts near your radio station to replace the damaged ones, but in any case, you will pay for the maintenance strategy you choose.


For radio station owners in some developing countries, it is unreasonable to send that bulky radio broadcast equipment back to the equipment manufacturer across thousands of miles. The high freight and agency maintenance costs are overwhelming them.


Fmuser hereby puts forward some necessary equipment maintenance costs and common methods to reduce these costs, hoping to help some radio station owners get rid of the problem of high operation and maintenance costs. Common equipment maintenance costs include:


Transportation Cost

Definition: When your radio station equipment needs to be mailed to the equipment supplier, you will bear the cost of this mailing equipment

How to Reduce the Transportation Cost?

You can share the high express costs through reasonable negotiation and communication with the equipment supplier. You can also find a local broadcast equipment maintenance service provider and pay a certain maintenance fee to obtain the corresponding equipment maintenance services.


But this is usuallyNOT SAFE: you cannot estimate whether the equipment maintenance costs and maintenance standards provided by third parties meet the standards.


If your radio station equipment still doesn't work as smoothly as it did before even after hundreds of dollars of the maintenance cost, you may need to buy the same equipment from the supplier again, which will be another expense.


Labor Cost

Definition: Your broadcasting equipment needs professional maintenance, so you need to pay for those who provide you with the maintenance services


Some potential labor costs includes:

The salary of equipment maintenance personnel

The maintenance cost of technical personnel of equipment suppliers (one-time or hourly)

The cost of equipment express personnel (often paid to express companies at one time)

The commuting cost of equipment suppliers (if you are close to your equipment supplier and you prefer to arrange technicians for on-site maintenance, you will need to pay some expenses of the personnel from your equipment suppliers, such as accommodation and transportation expenses)


How to Reduce the Labor Cost ?

In any case, you can't avoid the expenditure of manual maintenance costs, unless you want to take over all radio broadcasting work alone, you must then take the manual maintenance cost as an important part of radio station equipment maintenance expenditure


Truth is, even in some radio stations in developed countries and regions, the manual maintenance cost is still an inevitable topic, but through some reasonable radio maintenance planning, you can greatly reduce unnecessary manual maintenance costs. For example, by comparing the cost of equipment express delivery and maintenance by equipment suppliers with the cost of hiring equipment maintenance workers, you can easily make an equipment maintenance plan that best meets your budget.


Compared with the maintenance services provided by the third party (such as equipment supplier or local maintenance company), you should get more familiar with the basic maintenance and overhauling work for radio equipment, and constantly learn and practice. Only in this way can help you establish the awareness of equipment maintenance, reduce maintenance expenses, and makes long-term operation possible for the radio station in a healthy way.


Equipment Parts Replacement Cost

Radio station equipment such as high power FM transmitters, in addition to the aluminum alloy shell and some input and output interfaces, there are also many core parts, such as amplifiers, tuners, circuit boards, etc. To repair or replace these core parts will be costly.


If you are far away from the radio equipment supplier, and by chance, some core parts of your radio equipment just burn out, you may have to repeatedly order those taxes-included parts from the supplier's websites and pay for high freight costs.


Or you may choose to buy similar parts nearby, and ask your equipment maintenance engineer to do their jobs, but it is very likely that the slight differences between different parts lead to the mismatch between them and the damaged broadcasting equipment, which means your money may have been wasted.


How to Reduce the Replacement Cost ?

If you are worried about the quality of the radio equipment you purchased and expect to reduce its maintenance times, you should choose the best radio station equipment supplier before placing any orders.


But you should also realize that even with the radio equipment provided by the top manufacturer, the long-term&high-load operation will inevitably bring problems to some parts of the machine like aging and failure


Therefore, you need to pay extra attention to the periodic radio broadcast equipment maintenance, especially those hard-to-disassemble bulky radio equipment, and record the maintenance process in the work log, so that you may reduce the maintenance cost of the same problem and the replacement cost of core parts.


Plus, if any radio equipment fails and needs emergency repair, in order to prevent the loss of listeners caused by dead air for a long time, you should prepare some equipment parts featured by vulnerable and frequently replaced needed in advance, or contact the equipment supplier and ask them to provide daily equipment maintenance guidance or other online/on-site maintenance services.


Maintenance Budget Management

Equipment maintenance is very important, and you must invest a lot of energy and cost to do this work well, which can help prolong the service life of your radio equipment.


The importance of planning equipment maintenance expenses goes beyond all those most important steps. When you finally realize the balance of revenue and expenditure of the radio station, please don't be stingy to allocating part of the income as the equipment maintenance budget


If you have certain financial knowledge, you can easily understand that planning equipment maintenance budget is actually a reasonable investment behavior: when a radio station has been in continuous operation for several years, with many problems such as wear and aging of broadcasting equipment, maintenance then is inevitable.


But, always remember that equipment maintenance can only appropriately reduce the degree of machine wear and delay its aging, You can't let them stay in your radio station forever to serve you and your audience.


Although there are types of radio station equipment that are essential, and the maintenance cost for this kind of equipment is always high, but if you choose to place orders for the new same equipment instead of maintaining the used one, you may pay several times the maintenance cost. Instead, through reasonable radio maintenance budget management, you can ensure that your radio equipment can run smoothly for a long time. Even if there are some faults, you can have enough budget to ensure that the equipment maintenance plan can be carried out perfectly


How to Manage the Equipment Maintenance Budget ?

Capital and budget is the eternal topic for every radio station owner, which is also the fundamental basis for the survival of a radio station.


Once the equipment fails, you can either choose to carry out the maintenance work yourself or hand it over to your equipment supplier, but no matter which way, you will bear a lot of equipment maintenance costs


There are several ideas to help you properly manage your equipment maintenance budget:

Always remember: Create a monthly income&expense list

Ask yourself: Are those expenses really necessary?

Know the difference: one-time&ongoing expenses


a) List Your Monthly Expenses and Savings 

Equipment maintenance and overhaul should be the top priority of radio work. Even if you think there are still many other factors more important than this, you will pay a painful price if any radio equipment stops working during the streaming of radio programs due to lack of maintenance.


This reminds you to list your radio station's monthly expenses and savings, so as to allocate the budget for maintenance and purchase in a timely and reasonable manner.


Especially for some radio stations that are sensitive to cost and budget, it is very wise to save part of the radio station's monthly income for equipment maintenance, overhaul and purchase, even if you may not use the money temporarily, but you can't guarantee that you won't have to replace any radio equipment or carry out any maintenance and overhaul on the radio equipment in the future.


In addition, setting aside a part of your savings as the equipment maintenance budget every month can give you peace of mind.


b) Necessary or Unnecessary ?

There will always be some unimportant expenses in your quarterly financial statements of the station, but any expenses are necessary and reasonable for radio station equipment maintenance.


If you find that some unnecessary expenses are greater than the necessary expenses, you should be alert whether your income is used in some unimportant places, and make timely adjustments according to the actual situation


c) One-time or Ongoing ?

Every staff in a radio station, from the station manager, RF engineer to the radio host, does hope that the investment of all radio equipment is a one-time cost, which is reasonable.


If most of the equipment needs to be replaced frequently, it will undoubtedly add a huge cost to the station owner. For the station engineer, This means additional equipment installation and testing workload


For the radio host, this means that he needs to spend more time learning how to use the equipment.  A one-time cost investment, such as some audio input equipment and furniture, may be used in your radio station for many years if properly maintained; Some equipment parts may need to be replaced frequently in order to maintain their good working condition


Other radio maintenance expenses, such as daily necessities fare, utilities, etc. These are continuous expenses. If your budget is insufficient, you will need to reduce some one-time expenses and transfer this part of the budget as the expenses of equipment maintenance in case of need


4. Manage Your Station Affairs in a Better Way

In any case, the station manager should be responsible for all affairs of the station, but the station manager alone cannot achieve large-scale personnel and equipment management. Therefore, it is necessary to formulate a detailed station maintenance management plan and implement it periodically


1) Management for Radio Station Equipment

Audio equipment, furniture, electrical appliances, and even door locks. Regardless of the type of equipment, you should count all radio station equipment and studio equipment you have purchased, classify the names of this equipment, and input them into your computer database for storage


At the same time, you should also name the person in charge of each department. When there are some special problems on the broadcasting site, such as the program suspension caused by machine failure, each department can respond quickly.


The equipment maintenance personnel will be responsible for the machine maintenance and maintenance log recording, and the public relations work responsible for explaining the reasons for the suspension to the audience will be handed over to the host, The person in charge of the on-site command will be handed over to the main person in charge, etc... everything seems to be in order, right? The premise is that you have made arrangements for this broadcasting equipment and the corresponding person in charge!


2) Management for Every Radio Personnel

The radio host, RF engineer, on-site personnel, lighting guy, and even radio guests, all these roles are shouldering different tasks. The lack of any of them will lead to the loss of due fluency of your radio program broadcasting.


If you were a radio station manager, you should be familiar with the radio program process in advance, And monitor every part of the whole process from program production to broadcasting, and respond in time when some staff leave suddenly or ask for leave, so as to improve the overall work efficiency of the radio and ensure the normal broadcasting of radio programs


3) Management for Radio Broadcasting

The production process of radio programs, the maintenance process of radio equipment, the personnel transfer process, etc... you should establish special documents to record the repeated work process of each radio station. When you are ready to recruit new radio staff, you can train them through these records to ensure a better operation for the radio station


5. Find an Expert Radio Station Equipment Supplier

If you have an expert radio station equipment supplier, CONGRATULATIONS! You can often acquire a relatively complete radio turnkey solution, which means that in addition to the basic radio station equipment, some special services, such as equipment installation, equipment maintenance, and after-sales service, will also be provided.


However, whether your equipment supplier provides these services or not depends on your demand and budget. Radio stations in developing countries and regions often need turnkey services, from complete radio station equipment lists to installation and maintenance. The reason is mainly because of the lack of broadcasting expertise and insufficient budget.


Some station managers will install and maintain every station equipment themselves. However, it may arise some unnecessary damage to the equipment due to improper operation, which may increase the equipment maintenance cost.


Therefore, when looking for reliable equipment suppliers at the early stage of the radio station construction plan, in addition to learning equipment maintenance expertise, you also need to communicate the further maintenance services with the equipment suppliers, especially those with cooperation intention. Only in this way, when your radio station lacks equipment maintenance experience or is helpless in the face of equipment problems that are difficult to fix up, you can contact the radio station equipment supplier for help.


The following are some radio station equipment maintenance requirements frequently asked by some of our customers when they are seeking long-term cooperation:

Provide a complete equipment maintenance plan for the next few years after the successful establishment of the station

Provide free broadcast equipment maintenance manual and instructions

When some broadcasting equipment needs mail maintenance, they shall jointly bear the express cost

Provide reasonable online equipment maintenance support, including telephone and network

Provide on-site maintenance guidance for equipment maintenance personnel

Within the warranty time limit, parts or equipment can be replaced in case of machine damage caused by some non-human factors


Note: when you discuss these maintenance services with the equipment supplier, please implement them in the contract or text, and record what your equipment supplier promised you

Why is FM broadcasting still needed in 2021 ? 

Are you still using the radio? If you live in some developed areas, smart terminal devices such as mobile phones and computers have already become a part of daily life, but in some underdeveloped areas, broadcast devices such as FM radio receivers, are as important as food.


It means WHY to somebody, but quite easy the answer is: in countries and regions with backward infrastructure, living standards are limited, and radio is usually the only way of entertainment. In those underdeveloped countries and regions, using radio still has many advantages, for example, radio works as an information media with the lowest cost, it is also the most applied entertaining way that embraces the most audiences


What's more, radio is one of the best information transmission channels that have high quality and control efficiency in the COVID-19 pandemic prevention. The local town broadcasters or community radio stations are able to broadcast epidemic prevention information with the local language, which helps the local people learn the COVID-19 "How and Why" and add confidence to the listeners through this most localized cultural communication method.


Radio is only a small part of wireless broadcasting, the most important thing is radio station - as the signal transmitting site. COVID-19 is getting worse, community radio broadcasting, township radio broadcasting, and contactless radio broadcasting services such as drive-in churches and drive-in theatres have become one of the safest forms of entertainment in most developed and underdeveloped countries and regions. "We can do more than just praying around."


What do we need to know before setting up a radio station ?

Setting up a radio station is not as easy as it seems. You may need to consider what to broadcast on radio programs and how much continual costs you may need to invest. However, if your radio station is operated properly, you may also get considerable long-term income. Therefore, Before your first radio station buildup, you need to focus on the following key points:


Preview Policies Made by the local radio administration

In addition to studying the best buildup types pf a radio station, pay more attention and acquire the policies®ulations of local radio administration (e.g. FCC in the USA) in time can help avoid hefty fines for violations and help you formulate appropriate competition strategies, which is closely related to a lot of subsequent investment, for example, labor costs, radio station license applying cost, water and electricity fees, broadcast content edited cost, or time cost, the effort cost, etc.


Choose The best type of radio broadcast station you want to build

It might be confusing to the radio newbies to the main types of radio broadcasting: AM, FM, TV, and IP. But it is dead easy to see the huge difference in buildup budgets and equipment required for these four types of broadcasting. Therefore, pls attach great importance from the beginning when choosing which type of broadcast station to start with, ask yourself: can it totally meet your needs? How much budget is left? Always remember to consider the radio station type,  it helps with the stable operation of your station for maybe a few decades.


Mainstream options for radio station startup

Common radio broadcast - led by LPFM (small&private) broadcasting , including HPFM broadcasting (large&commercial), AM broadcasting (still in use), TV broadcasting (very expensive)


New radio broadcast - led by digital broadcasting (IP studio), is an emerging streaming media broadcasting on the Internet.


One thing is for sure for radio stations from developed countries and areas: to an expert radio station, with more equipment expenses always make a higher professional level of the station.


Does this work the same for underdeveloped countries and areas? Absolutely NOT. We have many customers from underdeveloped countries and areas. basic radio station equipment such as a low-power FM radio transmitter, several broadcast antennas, antenna accessories, and studio equipment packages, etc. are all that's asked for to their radio broadcast startup. These customers generally come from communities in some small towns, they broadcast radio over towns or neighboring communities that are near their radio station. They gained considerable popularity through local radio broadcasting with radio equipment cost only tens of thousand USD, which is far less than what was written in their radio station startup plan.


So, the professional level of the radio station which is broadcasting to means not-that-much to the local listeners. What means much then? - There are radio programs to be broadcasted and people can listen through the radio receiver means that much.


Some customers from developed countries have higher budgets and go for the best product quality. They favor the complete radio station turnkey solutions with a higher price, and the broadcasting equipment included can be applied in some large radio stations, such as some city radio stations or regional radio stations.


If you have less budget and only need to cover a few miles, the LPFM radio broadcast equipment can well meet your needs; If you have well enough budget and want to increase your coverage to over tens of miles, HPFM radio stations can be a good choice


Apply for a radio station license

Once you have an overall understanding of the resources you have, why not take some necessary steps then? Applying for a business license from an authoritative radio administration is the most important step in a radio station buildup. What you need to do is to understand the differences in different radio stations and to their licenses belonged, and get all ready before formally applying for a license - obtaining approval for an FM band will stay long and cumbersome.


As mentioned earlier, LPFM and HPFM are two mainstream station types of traditional broadcasting. Choosing either of these two methods, LPFM or HPFM, will inevitably encounter the problem of how to maintain the profit of the radio station.


If you choose LPFM station for radio broadcasting, you cannot send any form of paid advertising to your audience (LPFM is non-profit terrestrial broadcasting). But Low power FM radio station broadcasts a variety of audio programs, including music, news, public affairs, etc.


Although you can't engage in paid advertising, you can engage in underwriting instead, which allows you to accept corporate donations and express your gratitude for these donations during broadcasting. Because the Broadcasting Coverage of LPFM radio is very limited and usually appears in the form of community broadcasting, Therefore, the specific profitability strategy depends on the location of your listeners.


If you choose HPFM radio station, you don't have to worry about broadcasting paid advertising at all, because these profitable commercial operations can accept advertising and have a wider choice in terms of funds and programs. However, it is more difficult to obtain business licenses for HPFM radio stations and it commonly goes with higher applying costs.


How to schedule the inner affairs of your radio station ?

If you have submitted your radio license application to the local radio administration, what else can you do except for waiting for approval? Let's take over those inner affairs! To FMUSER, a radio station is like a company. As the decision-maker of this "company", you will be facing a lot of trifles such as what to broadcast tomorrow or how to make my station popular. The following are six practical rules summarized by FMUSER according to the customer feedback of some self-built radio stations:


Operate legally and avoid heavy penalties

No one wants to be severely punished by the local radio administration for illegal operation, especially when you have invested tens of thousands of dollars in the cost and countless energy for the radio station, you can't even give up this business directly! Therefore, always remember to apply for a license, prepare all paper material that needs or will be needed to submit, and fill in the application info according to the actual situation to avoid affecting the healthy operation of the radio station


Always invest reasonably

The construction plan of a radio station startup requires a lot of funds (if you always want everything to be top-level), including the purchase cost of professional broadcast equipment, radio studio space rental cost, warehouse rental cost, utility cost, salary cost, etc. These factors need to be carefully considered, If any of these factors are missing, you may be in great trouble, Therefore, finding your strategic partners stands above all especially in the initial stage of radio station construction. Of course, you can also choose to rent existing space and equipment (such as a radio tower and studio) for FM broadcasting, it is a great strategy, but not recommended for a newly formed radio station due to the over-high cost. Well, the choice is yours!


Integrate resources and build a team

Besides buying broadcast equipment, you also need to place them and of course, find someone to use the equipment. Do you want to do this alone? This is obviously impossible! You will be needing a technician for the broadcast equipment maintenance; You also need several radio experts who are responsible for editing radio programs and on-field work for live broadcasting, etc. So go get some radio broadcasting talents to your startup schedule.


Exclusive business plan for your radio station 

What else do I need to know except for the station buildup cost and local radio policies? You may also need to decide how to make a real broadcast station. Is it a small, low cost but low-profit LPFM radio station you're going to build or a large and highly profitable commercial / HPFM radio station or other types of radio stations on planning, these decisions are closely related to your cost, which also makes great influences on your radio program types in the next few years.


Some additional factors should be considered as well, such as the terrain surrounding your radio station, is it flat or hilly, a flat terrain allows a better broadcast antenna coverage for the broadcasting; Are you going to build a tropics radio station? If yes, then you need to consider the weather things such as humidity and high temperature, these factors may bring negatives and increase the cost input to your radio station buildup, especially for the cost of choosing the best radio station equipment. How do I gain a better review from my radio programs? You will meet all kinds of problems during radio station construction. It is unwise to fight alone, you then need some cooperation at this point.


Fortunately, as an expert in professional radio station buildup, FMUSER provides complete radio station turnkey solutions and low cost radio station equipment for radio buyers with every budget. What's more, online real-time support is also available, from structural planning of your radio station to management of each small step needed to be taken before and after the radio station buildup.

Needed radio station equipment for pro radio broadcasting

If you want to broadcast audio programs with high quality on the radio frequency, then having the best radio broadcast equipment is still necessary. Don't forget the product performance and buying cost-related info. The most important thing is legal radio broadcasting, which requires operating under rules established by local radio administration, such as radio permission or broadcast band requirement. A basic LPFM radio station may need fewer big brands broadcasting equipment than a commercial FM radio station do (cause with a higher cost), but even so, creating a checklist for complete broadcast equipment still means a lot for either radio station type, which also works for AM and Digital radio broadcasting.


For FM radio broadcasting, the equipment checklist for a complete FM radio station includes three basic types of broadcast equipment:


Equipment for FM signals transmitting - Most applied in a radio engineering room for radio broadcasting to the end-users.

Equipment for audio processing - Most applied in a radio studio as front-end audio processing equipment

Equipment for audio inputting - Most applied in a radio studio to input audio signals of radio programs delivered by the host or guests.

Common FM Transmitting Equipment Checklist Includes 

Studio transmitter link Equipment - includes digital STL system consists of live streaming encoders and decoders, parabolic antennas, network switch, and other devices such as generator, audio&video input lines, etc. While microwave STL consists of STL antenna, STL transmitter&STL receiver. The STL system is used to connect your studios with the transmitter site and ensures audio transmission quality.


FM broadcast transmitter - key pieces of equipment to build a basic FM radio station, made to process FM signals and sent to broadcast antennas


Antenna System Package - includes antenna feedlines, coaxial cables, cables connectors, and other accessories, the most important pieces is broadcast antenna arrays, with more arrays comes with additional antenna gain so as to reach a more effective transmission


FM Combiner for Antenna - due to the high cost of multiple antennas and limited space of the broadcast tower, an FM combiner could dramatically reduce the cost of the FM transmission system by taking the output power from the power amplifier and put them together into one FM antenna array.


Antenna Waveguide dehydrator - also known as radio air compressor, it is an important piece of equipment used to provide dry and compressed air to the rigid transmission lines, which is commonly seen in the large radio stations


Power Amplifier for FM Transmitter - used to grab the signals from the FM Exciter and expand to the power that is legally applied by you


FM Stereo Generator - functions by pre-emphasis and low-pass filtering, an FM stereo generator is used for external FM audio processing system, to help reduce the influence of receiver mixing caused by multipath and transfer the complete AES MPX composite baseband to the exciter. To summarize, an FM stereo generator is a converter that can receive signals(audio) and transfer them into FM baseband format.


Composite Stereo Audio Switcher - switching equipment used to switch stereo audio between FM stereo generators (if with multiple)


FM Exciter - used to grab the audio signals of the FM Stereo Baseband from FM Stereo Generator or Composite Stereo Audio Switcher


Broadcast Antenna Switches - a device used to switch between the broadcast antennas that are applied with other transmitting broadcast equipment such as radio transmitter and receiver.


RF remote control - an easy-handling wireless device used to release RF remote instructions to the broadcast equipment (no need for aiming directly at the equipment), plus,  in case of multiple broadcast antenna systems, it monitors the RF transmitting system and gives out warnings when the system went wrong.

Studiohub - it usually refers to Studiohub wiring standard for the connection of analog and AES audio over RJ-45 audio connectors or RJ45 to balanced/unbalanced audio cable wiring. PS: The “RJ” in RJ45 is the abbreviation of Registered Jack, which is a standard designation originally found in the early 1970s for telephone interfaces by the USOC (Universal Service Ordering Code) scheme of the Bell System


Network Patch Bay - a wiring device that uses cables to interconnect the network computers in the local area network and connect to the outside lines including the internet or other wide area networks (WAN). As a device used as a static switchboard, the Network Patch Panel can be used to interconnect and manage fiber optic cables and connect all devices through the Network Patch Panel and Cat6 cables. The patch panel can provide simple and accurate wiring management for the network, and its great flexibility reduces the difficulty of technical fault maintenance: when content needs to be changed or fails that need to be fixed, there is no need to rewiring or to move any equipment, and a technical fix-up can be also be easily reached.


Audio Cable - an audio connection line used to transfers audio signals (analog/digital) from the audio source to the receiving end such as a speaker. The most commonly used cables are analog RCA cables, which were also called a jack, cinch, and coaxial (originally named based on their construction or connectors instead of types)


Punch-down Block(a cable termination device,where wires are connected into individual slots, it is common in telecommunications, but it’s also found a lot in older broadcast facilities.)


Network Switch - an important managing block (optional from hardware-based devices for physical networks management or software for virtual management ) used for the connection of multiple network-based devices such as computers, and some internet of things (IoT) devices such as wireless inventory trackers. A network switch works differently from a network router: it sends data packets between devices instead of sending them to the networks, which enables a communicating freeway for information share between connected devices. Plus, the use of a network switch helps manage traffic either coming into or exiting networking and keeps electrical signals undistorted, etc.


Network Router (or a default gateway) - A switching device mainly used for internet access: to send and receive data packets on computer networks by a direct connection to a modem through cable wiring, it is also used for coupling networks or VPN connections. A network router works differently from a Network Switch: it sends data packets to the networks instead of sending them between devices, which helps choose the best route for the "magic travel" of information share (personal &commercial) between global computer networks, and of course, to keep the information safe from IT hacking, threatening, etc.


On-Air Broadcast Audio Processor - a piece of multi-band audio processing equipment applied with radio broadast transmitter in a radio station, most used to manage the peak modulation of the transmitter by control the clipper (bass clipper and master clipper) and digital MPX Stereo Generator. An FM audio processor is also used for audio input enhancing, for example, customize air sound can make a special signature voice for a commercial radio station.


RDS Encoder - a device that can transmit FM radio signals, RDS signals (digital information) such as brand information, audio program information, and other information of the station. RDS is abbreviated from the radio data system, which refers to a European Broadcasting Union (EBU) communication standard, this standard created a higher level of signal quality and spectral purity for the FM transmission of an FM radio station, and it also creates a fully digital environment for the radio station operators.


Telephone Hybrid equipment - A telephone hybrid is mainly used to enable to record or broadcast a conversation between a caller and a presenter or use live callers or reporters for radio broadcasting. A Telephone Hybrid equipment is known as a broadcast telephone hybrid or telephone balance unit or a telephone fork, which provides an interface between a standard telephone line and a mixing console and converts between two-wire and four-wire forms of bidirectional audio paths. The use of Telephone Hybrid equipment realizes an easy turnover between the telephone and mixing console, therefore it is very suitable for use on location, besides, it can also reduce not only the calling cost but also the risk of VoIP telephone and traditional analog phones, and create efficient management even in the peak load time.


PABE (Private Automatic Branch Exchange) - an automatic phone switching system managed by private organizations, which is built to meet the needs of multi-lines for in-house and outside calls. PABE is abbreviated from private automatic branch exchange, it is one of the needed private solutions for a radio station. PABE allows a cost reduction of using public telephone networks because internal calls can be placed for free with only a few public telephone lines. PABE also optimize the internal communication inside a radio station, with few buttons made to be pressed can a simple call to each other from inside.


FM Off-Air Receiver - an FM radio system that is mostly seen in pro radio stations and regulatory authorities, which is used to monitor the signal during the radio program or to deliver a high-quality audio feed for program distribution throughout the broadcast facility with adjustable analog and AES digital audio outputs. The use of an off-air receiver lowers the cost of separated monitoring of multiple radios, and respectively increases the quality and continuity of the regular monitoring.


Monitor System - a device functions by FM radio monitoring and measurement, which enables repeated FM multiplex signals to be reproduced and transferred between different devices with a built-in digital filter. A good Modulation Monitor / FM Analyser usually allows GSM Connectivity via the optional external GSM Modem, so as to have easy monitoring of channel status or receive audio signals through your mobile phone at any time and space.


Server Rack - a metal-made closed space structure used to store, rack broadcast equipment of more than 6 units (optional from 1-8 units). A server rack can be stacked or extended due to its versatility, and the most common types of server rack are 1U, 2U, and 4U (8U is optional but less seen), for a large radio station, a 19″ case serve rack is the most ideal model for the rack equipment. The use of a server rack helps reduce the use of floor space for the radio broadcast equipment, simplify equipment wiring and technical maintenance, consolidate the limited resources among the tiny rack space, for example, to centralize cooling airflow, organize a much expandable inner space, and a better and easier interfaces integrated management, etc. The rack server also ensures a better working environment: to protect the tech guy from being harmed by accidental bumping or touching of high voltage electricity stream of the equipment, cables, etc.


IP audio codec - an audio device used for audio signals converting (analog to digital), audio encoding, and storing. Audio signals will be sent over both IP networks (wired broadband) and wireless broadband networks (3G, 3.5G, and 4G) by IP audio codecs which use audio compression algorithms. IP audio codecs are most applied in distance distribution and high-quality audio signals transmission, for example, remote IP audio broadcasts and audio distribution for multiple STL links (studio to transmitter links or STL links) or networks/stations/affiliates/studios.


Broadcast Satellite Receiver - a piece of radio broadcast equipment used to satellite audio program receiving, and audio distributing one-to-many through the network of communication satellite, radio signal, outdoor FM antenna, and broadcasting center. The satellite receiver is commonly seen as one of the most key equipment of audio distribution applications, with types divided into HD receiver, general receiver, digital receiver with recorder, and encrypted channel receiver. The use of the stateliite receivers realizes the versatility of a high-quality audio broadcast.


DAB+/DRM/HD Radio Encoder - a hardware encoding equipment that is used to transmit the AES or analog audio streaming in the proper transport protocol in the field of DAB+, DRM, and HD radio broadcast transport. A hardware encoder is designed with a smaller and portable box, it works more stably and has a lower buying cost than an open-source software encoder. PS: DAB+ is a new radio broadcast standard of Digital Audio Broadcasting used in many countries and regions, originally defined by the WorldDAB Forum. DAB+ works incompatibly with DAB, which means the DAB receiver cannot receive DAB+ radio broadcasting. In terms of efficiency using for radio spectrum, DAB is better than analog FM broadcasting, DAB can provide more radio services for the same given bandwidth, for it usually uses the spectrum more effectively and is stronger than mobile listening noise and multipath fading than analog FM broadcasting, although FM provides a wider coverage area, the radio signals are weakening as well. Other global terrestrial digital radio standards include HD Radio (Mexico & the U.S.), ISDB TB (Japan), DRM (Digital Radio Mondiale), CDR (China), and related DMB. About DMB: it refers to "Digital Radio Mondiale", while Mondiale refers to "global" in Italian and French. DRM is a set of digital audio broadcasting technologies used in the frequency band working for analog radio broadcasting such as AM, short wave, and FM.


Audio Patch Bay - a wiring switching hub used to centralize inputs and outputs of different pieces of audio equipment. An audio patch bay is mostly placed in a rack server in a radio rack room, which allows a better technical maintenance condition and ideal hardware management (no need to move for plugging over and over again ) through audio signals rerouting, most importantly, it lowers the equipment replacement cost: less replugging and unplugging almost avoid equipment interfaces wear&tear, which means a longer product life expectancy. There are three basic types of audio patch bay, which are parallel patch bay, half-normalled patch bay, and normalled patch bay, most audio patch bays consist of panels with rows of interfaces used for audio input and output on it, while two rows on the rear, and two rows on the front. The audio patch bay can be applied with other audio equipment such as an audio processer, audio mixer, etc.


Silence "Dead Air" Detection Equipment - a device that can detect the dead air situation, controls the sound level of audio input for the radio station, and send a silence warning via email, SNMP, or analog optocoupler outputs. Silence detector is most seen in professional radio stations and TV stations and can be easily be applied with other broadcast equipment. About dead air: dead air refers to an unintended interruption (usually out of sound) or a period of silence in media broadcast with no signal, audio, or video is transmitted mostly because of bad program material or operator error or for technical reasons. Radio dead air may be seen as the worst thing ever to be expected especially for expert radio broadcasting. To the station owner, dead air can bring considerable losses in many aspects, for example, the loss of sponsored advertising revenue and online listeners. Delegation Switcher(to switch between studios and other audio sources, selecting what goes to air)


Broadcast delay - a tool used by broadcasters in way of delaying the broadcast signals to prevent mistakes or unacceptable content from being broadcast such as sneeze, cough, or a short comment needed from the host, the broadcast delay is also known as profanity delay, it offers enough time (from a half minute to even few more hours) for the broadcasters to censor the audio (and video) profanity or other unqualified content for the broadcast, and remove them at once in case any negative influences. Broadcast delay is mostly seen in radio broadcasting and TV broadcast, like live-sport, etc.

Common Supporting Equipment For Radio Stations Are :

Air conditioners (for studio room and engineering room) - to provide cool air for the equipment and of course the best radio experience for your guests


UPS - Uninterruptible power supply (UPS) is a kind of electrical backup equipment used to protect hardware equipment in a radio station when an accidental power interruption takes place. To reach that, a UPS provides enough emergency power and can be applied not only for a small place like an office but also for a large suburban area. Common lasting time for a UPS will only be few minutes (based on output power), but it is far enough for the generator technical  maintenance.


Generators - a device used to produce electric power transformed from mechanical energy and supply to the radio station


Furniture - to provide free space for different applications, e.g. the desk space for putting studio broadcast equipment like microphone and audio process, the lounge space for radio guests, etc.


On air device - includes on air light and on air clock. In an expert radio studio, an on air lamp is a light-warning device that can be mounted on the wall, mainly used to cause attention to people who might break unintentionally into places where you're live broadcasting (and ruin your plans by chance), and of course, it is also an important device to display your how professional your station is and to remind everyone to be quiet on the live broadcast scene. while the on-air clock is a piece of information reminding device functions by time&date display, count-down timer, advertisement interruption, etc.


Studio Acoustic Wedges Foam - a foam panel made from polyurethane/polyether/polyester and cut in the shape of the cuboid, usually used for soundproofing in a radio studio by attenuating airborne sound waves, reducing their amplitude so as to control noises.
