[TenTec] trouble with Scout

[MadScientist]

I agree with Rick. I have seen this failure mode in Scouts.

However, one more thing beyond cleaning is physical distortion of the connectors inside the radio.

They are not as difficult to get at as they seem so have a close look at them.

Then simply connect the driver's output directly to the band module.  This effectively gives you a 5 watt QRP transceiver.
