Analog RCA and XLR audio inputs, AES/EBU digital audio and USB audio inputs

This package is based on STMAX1000 FM transmitter board. This is a small, yet well built and reliable package with DSP stereo and RDS, antenna,  optional mains power supply, many kinds of audio input connectors and coaxial antenna cable. This package can also be powered from a car battery (13.8V-15V). A perfect small transmitter for advertising, small community radio, church radio, portable or improvised installations and small radio stations in Africa and other remote installations, special occasions, drive-in cinema wireless sound distribution, translation, tourism…. .

– Excellent audio quality and stereo separation (DSP+DDS modulator)

– USB audio input for direct connection to PC or laptop
– High quality ESD protected RF hardened balanced inputs
– Digital AES/EBU audio input

– Fully portable and can run from car battery or battery pack.
– Includes antenna and coaxial cable for antenna

– Does not have the MPX input (you probably don’t need one anyway)
– The CyberMaxFM+ units have better RF S/N quality than the Nano series (not an issue in many low power applications in remote areas)


It is never easy to predict range. Enough power for up to 1km of range with good antenna and location on a mountain top, in typical setting a few  hundred meters can be expected. More in very good conditions. This depends a lot on terrain configuration, type of antenna and especially the location of the antenna, coaxial cable quality (and length) and of course also on quality of receivers and their antennas.


– STMAX1000+ in enclosure
– An antenna (Low power half wave sleeve dipole antenna)
– 5m of coaxial cable with matching connectors installed

– Transmitter runs off 15V @ 1A max. If you don’t own one you can either decide to buy it locally, use car battery or 15V solar power setup or you can buy our mains power supply and run off the grid (recommended).

What parameters can I change via PC remote control?

How do I wire up the transmitter, antenna and audio sources?
Look at the image below (click to enlarge) for an example of a nice radio station with some studio items. At the bottom of this page look for the links to other items that you can use to setup your radio station (WHAT ELSE WILL I NEED AND IT WASN’T INCLUDED? and WHAT CAN I USE AS AUDIO SOURCE?).

What is RDS?
Radio Data System, basically it displays station name and sometimes song name and similar information on a compatible radio receiver. Very popular in Europe, less so in the US. Requires connection to a PC at the time of programming, but retains settings even when powered off.

Need more studio gear?
Need audio processor? Check these.
Need a link from studio to the transmitter site? How about these.

Important: Due to large size and irregular shape of these packages the website often gets shipping cost wrong. For exact shipping cost please contact our sales department, be sure to give them your exact address and they will quote you shipping. It also does not hurt to ask for a special discount.

Also recommended:
We recommend AA-230 ZOOM antenna analyzer for checking SWR of the antennas. Coaxial cable grounding kits can be purchased here, they ensure lightning protection when used with grounded antennas. They should be installed at the antenna (if needed, most dipoles are grounded), at the tower base and at the point of entrance into building. Also use self-sealing tape which turns into rubber and prevents moisture from entering your connectors and coaxial cable.

– Your PC. Just plug audio cable into your sound card.
– CD player, MP3 player or any other music reproduction system
– Mixing board with microphone and other audio gear

– Power supply (if you get ours) requires mains cable which can be purchased in your country (each country has a different mains plug and we don’t carry all). This is standard cable used in your PC for example and its price is typically around 1 US$ or less. You can get it in any electronics store, such as radio shack, circuit city, any computer store etc.
– Good taste for music and great skill to put together a program that will dazzle your listeners
