RadioShack TRC-446, No receive...

[Hurricane892]

I recently found this radio at a thrift shop for $12. It's a nice radio, for what I gave for it. It has WX and the original mic with channel up/down buttons.

However, I tried it yesterday and it doesn't receive. I was told that it is indeed transmitting by a local CB friend. The first thing I would assume is the speaker is bad, but I know it's fine because WX can be heard loud and clear. The only other idea I have is possibly the mic having a short and not allowing me to receive anything. I sure hope it isn't the mic, but if need be I could rewire a Galaxy mic that I have no other use for to work with it.

Does anyone else have any other ideas as to what the issue could be?

If you have modulation on AM, the PA works, and the audio amp works through the speaker with WX, the audio stages are clear. Not all radios require a mic to complete the audio switching path. RS's Din mikes had pin 5 connected to pin 1 with the PTT in receive traditionally grounding pin 5 inside the radio when inserted. The Sears Roadtalker AM set I have on my bench is one that requires the mic inserteted unlike earlier Sears unit. In this case, the mike provides the ground return for the speaker. That's probably not the case in yours if the WX works. Sounds like you have a simple switching problem.
