Turn ur sqelch to the left and it will start making noise, and then turn it to the right till the hissing quits and then stop...and turn ur mic gain and RF gain all the way to the right and that should help...and use channel 19 the truckers channel then that the channel mostley everybody uses

Turn your squelch until it makes noise then make a quarter turn back just until it stops then you should hear people.

A number of things....faulty speaker (you can scratch test this with a torch 1.5 volt cell....cell pos goes to 1 speaker terminal
and cel neg goes to other speaker terminal..you can conect it any way around with flying leads from the cell...just keep touching the terminal with one flying lead...you will hear a scratching sound in the speaker) have your mike checked...test the tx/rx relay on the circuit board for tx/rx switching, or, a failed
driver transister in the output stage....the list is many

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.

I need a mic for my TRC-447 where can I find one? they no longer carry it at radioshack.


You have not specified which country, state or county you are in so we cant even suggest a shop in your country. Find a local CB dealer and take the radio there, they will be able to wire up a microphone for the radio.

Radio shack trc-447 cb. no controls function, radio turns on. Channel displays 8. switches do nothing,


The units have a reset code that protects the PLL brain from damage from voltage spikes. Ship it in and I'll get it back to normal function for you, providing the PLL has not been damaged.

According to the service manual for the TRC-447, the only adjustment is for "power" which is #L205. The only other step in the transmitter alignment is for the "S" meter.
On the Cobra, VR4 is AMC, L14,L13,L12 is AM power.
