Question about Uniden PRO510XL 40-Channels Base CB Radio
A friend and I each have a Uniden pro 510xl CB radio in our trucks. His radio will transmit (I can hear his messages) but will not receive (he can not hear my messages). We tested both radios with others in the RV park and confirmed that it is HIS radio which has the problem.
I switched microphones in case switching in the microphone was permanently turning off the incoming amplifier, but no change. There is a hiss from the speaker, and touching a voltmeter to connections around the amplifier and speaker does produce clicks.
It's as if the incoming signal never makes it to the audio amplifier.
We looked for obvious cold solder joints, no luck.
Any suggestions please?
If you look on the solder side of board you shoud see a straight line of 5-7 solder joints, look on the other side the audio vhjp is a bmack thin retangular ic chip. Not to worry you wont hurt anything by doing this. Its an old cb tech trick to test audio chips.GOOD LUCK.
Oh one other thing does the radio have same same problem in either vehicle? A insulating washer on the antenna bracket can cause this also,
Happy New Year , Tom
