I have a Cobra 29 LTD NW that had garbled receive audio after warming up for about 5-20 minutes (was clear and strong when first powered up). I put it on the shelf for about two years. Then I ran across a receiver mod on eBay. New T27(I think) and 3 new diodes. I installed the components as instructed hoping to alleviate the garbled audio. Surprise, no audio at all! So, I hooked up a speaker to the P.A. jack and got audio (yes the meter is working also) and the mic (Astatic) worked for P.A. With the radio in CB mode (as opposed to P.A. mode). the meter still shows the same receive level (about S4 +/-) as in P.A. mode. The radio transmits just fine, showing nearly full swing on the meter and good Tx audio quality heard by another radio. So to sum it up, Tx OK, no Rx.
any thoughts? worth fixing?
