I have a General Lee radio. Bought it used from a pawn shop for a really good price ($70, don't think they know what it is). I turned it on worked great, for maybe 12 hours off and on. The next day it won't rx even though I still hear myself in talk back. I work hours where no cb shob is open before or after work. Any ideas? My other radio still works on the antenna and coax.

Could be a bad tr. In the receive circut its a small kinda half round black thing with 3 legs coming out of it. Ive had 5 of these radios it happened to me. The board in a galaxy 33 is the same if that helps. But i would try a mic first but it sounds heat related so im thinking the tr(short for transistor).

Depending on how old it is, it could have bad caps. Could be the switching transistor, mic... Any number of things. It is the kind of thing where you have to start checking things down the line looking for the issue. Start with the simple things like the mic, cold solder joints. Look for obviously burnt parts. After that it gets a bit more technical checking parts in the TX section.

Hopefully its just a bad mic wire which would cause the radio to have no RX. Try a new mic. Good luck!
