I double checked the service menu and its all in line as it should. In case of a defect: check the microphone by listening to the AM or FM.
When FM and AM are operational there is nothing wrong with your power amplifier. For CW you need to connect a morse key or paddle to have output signal. The red wire is a replacement/repair for the trace that burned after a flight to Kangerlussuaq (OX) in 2000, because a small piece of aluminium that was glued to the chassic as a retainer for the PCB was shaken loose and happened to land on the switch as a short. Im still learning some things on this radio. SSB requires a signal from the microphone: only when you are talking there is a signal generated. Perhaps a CPU issue, I have noticed some irregularities with my FM repeater shift, sometimes it doesnt shift and then it does, I havent ruled out human error on that one though. I know there was no surge or lightning involeved. Im thinking the same thing that it would be almost omposible to lose all of the finals.
I tried running it through a linear amp I had and it doesnt even trigger the amp when transmit is pressed, Like I said there is a signal I can pick up on my handheld when Im within about 100ft of the unit but thats about it. I am using a 25 amp power supply which should be adequate. The display doesnt show anything on the power meter when depressed. It puts out a signal that my handheld can pick up but it wont even register on the SWR or power meter. The voltage is at 13.7, it dips a little when I push transmit to 13.6, This is on the display, I double checked my power supply and it is accurate.
