Need mic wiring diagram for trc-446


you may have to order one from radio shack because the wireing diagram is for that radio and mic only . You cannot use another mic on that radio , only the one that comes with it . If you are patient enough and have another mic with the same controls you could wire it up. it has to be ( I think a 6 pin ) ???

Cb radio trc446 rewiring microphone color coding


if you pulled it completely out you may have a problem . Trial and error is all I can tell you.Get a volt meter and check the mic pins on the radio . Ground one lead and touch each pin for ohms the first one to make noise is the ground. then touch the ground with one lead and touch the next pin and the next . now if there is any left over wire on the plug you can rewire it , then go from there.

Need the wiring for mic on trc 502


My understanding of the TRC-502 is that it is 49 MHZ not CB. With that said I cant find
a microphone diagram for that specific radio. I found a 503 but that is a CB. I couldnt find a
wiring diagram for either radio. You could always call Radio Shack or The Shack, contact them online or call and ask for the info.

Need a replacement mic for a TRC 447. Can't find one, and Radio Shack is of no help....AT ALL !!!!


The radio takes an electret condenser microphone. You can also use a dynamic type in a pinch, but audio quality and strength varies depending on the microphone. Several sources for replacements came up from a search, and here's one. If you need to rewire the plug or install a different one to fit the replacement mike to the radio, wiring information is here.
