Customer Reviews

 "This radio system has kept our community informed during our recent flooding event. Among other things, we broadcast road closure and detour information that has helped residents navigate during the crisis.”
Craig Colvin, WV
 
"I just want to thank you for a great product. I'm a radio hobbyist and I'm enjoying the radio and really impressed with the package." 
Ken Parrish, TX
 
"I've had my Talking House AM Radio Transmitter for nearly a year. I use it every day to listen to my favorite radio shows and music on my restored vintage tube radios. The Talking House transmitter broadcasts a clear signal to every room in my house and I can even pick it up clearly on the car radio when parked in the driveway. It comes as a whole unit and doesn't require any assembly other than plugging in the antenna and the power adapter."
Jonathan Sanford, MI

Free Radio Systems

Free-Radiate AM Radio Stations

On-Property Coverage
If you represent an educational institution, FCC Rules Part 15.221 allow the use of a transmitter without a license, as long as the signal coverage extends only to your property. There are no restrictions on antenna height, transmitter power or content. 

Transmitter TR.6000 Model 15.73 provides up to 10 watts of signal and is capable of many miles of coverage on large parcels.

Free-radiate systems are customized to the application. Antennas are typically mounted on a flat building roof or pole with the transmitter and audio equipment located inside the building. Email us your desired goal; and we'll recommend a setup. You will be able to select from special cabinets, mounts, processors and audio solutions.
