TRC 503 Mods


do you mean the trc 503 or the 503A . one is a hand held the other is a CB which neither one has any good mods except for turning it up a little for power and a little modulation.

I have a TRC 502A CB radio that hasn't been used in about 5 yrs. I recently tried to use it and when I transmitted, the audio came thru the speaker. Any idea what's wrong?


it could be grounded inside...Somebody may had it set for Talkback features.. Take it apart look for speaker wires (see if soldered to resistors) if its shorted seperate wires ..just have speakers wires attached. Try external SPKR. Try different mics or radio may have gone bad completely.
