I have completely run myself ragged on this radio.
Let me refresh everyone on it. When I bought it, it had no transmit or receive. I used Deoxit on all the switches and that brought SSB receive back to life loud and clear,
I replaced TR5 and that brought AM receive back loud and clear, receive worked great.

So I started working on the transmit problem using a stock cobra handmic, then I thought these were wired for electronic switching and the radio is relayed and that may be the problem.
So I dug out my D104 with the TUG 8 base and flipped the switch from electronic to relay, keyed the mic and the lights went out, blowed the fuse, when I replaced the fuse, all the lights came back on and had receive on SSB but not on AM. Replaced TR5 again and got back AM receive. Put the hand mic back on, still no transmit and blew TR5 instantly, also now the channel selector light goes out and meter lights dim when the mic is keyed in SSB, but stays on in AM.
I have tried locating the connection for TR5 in AM and SSB, somewhere in there is a blown component when in transmit. I am having no luck.

Please, someone should have run into this before, I would appreciate any and all suggestions or info. I have had to just lay the radio aside and walk away till I can get some help, I am almost positive it is nothing to difficult, but either I am overlooking something or It is more serious than I am thinking.
If you have any ideas?

Thanks, Mike
