I have a cobra 29 nw classic and the problem is when I key up and let off the mic the radio stays transmitting but with no sound, I have changed the mic numerous times and all still do the same thing this just started happening and the only way to clear it so I can recieve again is to shut the radio off. other than this people can hear me fine and I can hear them fine.
What happens if you "key up" and "let off" and the transmitter "hangs", you remove the microphone plug from the Cobra ?
Will it still be transmitting or will it stop ?
If it stops, the problem is in the microphone with a "hanging" switch which you can easily clean or replace.
Iif it keeps transmitting while the mike is disconnected, there is a problem with the Rx/Tx switching circuit. This needs further investigation by use of a circuit diagram.
