Question about Cobra 25 LTD 40-Channels Base CB Radio
Does it seem to be talking on the right channel??
Check to see if D10, which is supposed to be an N1004 diode, and see if it's been replaced with a jumper.
If that's the case, then the final is volted. This mod gains some wattage but can make a radio dirty. Putting an N1004 back in may fix the issue.
Usually the radio will deadkey on the right freq.
The VCO could be off, and the radio may need to be aligned. Could the person you got the radio from have randomly turned VR's in the radio trying to mod it?
Without an ocilliscope you cannpt fully align the radio, but if you have a volt meter and a watt meter, you can do some of the alignment.
here is an alignment guide.
But if you can hear people on the correct channel, and they can hear you fine, it could be just a volted final.
