I have a friend who has a 2970, he tried to wire up another mic and shorted something, now it is stuck in TX, even with mic unplugged,, anyone know if it could be a shorted TX transistor or something in that nature? it is stuck on TX and 26.000 mhz

RCI 2970 bit problem
- Thread starter skybolt58
- Start date
Some of these models had a microprocessor reset button inside. Might have been the earlier 2950's only, not sure.
Try disconnecting from power, turn radio ON and leave for 1 minute. This will drain the capacitors inside. Reconnect & try out.
If that doesn't work, may need to go back inside radio and disconnect the CPU memory battery, again disconnected from power and turn rig ON and leave for 1 minute. Reconnect battery.
Also wait and watch this thread for other tips.
Hope you don't have a bad component.
Good luck

Like Wire Weasel, I'm not sure if it would relate to the 2970, but when a 2950 does what you describe it is an indication of a short in the cpu board. The only way to resolve the problem is to replace the board.

Hey Skybolt
If it has a reset button, should be on the same little board near the front of the radio behind the face/display. It's the same board the 2 or 3 sets of pins are on that you change the jumper to do the conversion for 11 meters.
