Thank you very much for the great explanation Barracudahockey. Never understood the relationship of hockey and barracuda

I have seen couple of videos planes got crashed due to radio locked out and no signals were being trasmitted, even saw a video of turbine crash. Which radio was that I don't know. But The old flying field I used to fly, there was a guy who only flies turbines, his brand new turbine crashed due to radio lock out. and He told us that couple of times his radio locked out, and I guess he was using JR. Which radios have lock out problems?
