hello
my 430 is playing up ! it always shows RX on the Com side and i have no reception (when pressing the volume knob no change in RX) also i can not transmit but it shows TX in didplay
when plane in in the hangar ond no radio reception than there is no RX sign in display
if anyone has a hint for me i would be greatfull before i get an avionic shop on it
thanks
If the 430 is in the #1 position try turning off the audio panel and re-testing, there is an outside chance it’s the audio panel.
Do you use USB in the aircraft? Switch it off. Many converter produce electronic noise which breaks the squelch.
