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, Texas 
 
"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, Michigan
