Question about Radio Shack Radio Communications

1 Answer

I have realistic TRC-431 Base set. It receives well but will not send. Even when I change microphones with one from a working unit it will not send any sound. All another radio receives is an electric hum. Any suggestions. I do not have a repair shop close buy. Hoping I could figure this out as the old radio is in nice shape otherwise.

If you do get a hum, that would indicate that the transceiver is working. What is likely, is that the antenna is somehow not broadcasting.
Check out the connection on the coax, and the type of antenna your are using to broadcast.

I need a new channel changing Mike for a Realistic TRC 476. The cord for the Mike was cut and even though repairs were done the radio just scans through every channel very quickly and constantly.


You should check the new cable wiring connections. There is a resistor in that microphone that connects to the channel button circuit, it is (electrically) between switch 5 (up) and pin 3. If this not present then it may be causing your issue, IT is also possible that the diode for that circuit (located on the main board) got damaged when the cord was cut. diagram: http://www.cbtricks.com/radios/realistic/trc_476/476_print.htm

there a several things you can check yourself with a minimum of tools or test equipment. this model has been around for several years and voice coils do expire in the internal speakers as they age. attempt to locate a known good external speaker with a 3.5 mm plug and see if the receiver can be heard through it. if so then the internal speaker has seen better days and the solution/s should be obvious. also in this particular model the receiver output is controlled by the microphone switching and an open receive line in the mic cord/cable or the plug itself would render the receiver unhearable. check with another known good microphone wired for realistic radios (5 pin DIN). the microphone might also have been rewired improperly. make sure the squelch is in the fully counter-clockwise position and the volume is adjusted to a suitable level while testing, 12 o'clock or higher.
