Cannot even begin to answer . It is complicated and tedious process but it all has to do with your processor and that its not obtaining the correct frequencies via the oscellator. In other words its in your vco section of the radio so get a schematic and a block diagram and go for it.

Strange problem indeed, this is why I don't like Cobra radios, they're no good. But try adjusting the receive gain on the radio, if that doesn't work, you might need to check the antenna, check if it is connected properly, or if the antenna actually works. Honestly though, if you want a solid performance radio, go Galaxy or Uniden, no Cobra. I worked with radios for years, and Cobra has failed to meet my expectations for a good radio, they may have a lot of features, but they have no reliability.

Sorry :(
Anyway, I hope this helps somewhat.

SOURCE: Have Cobra 29 LTD CB

Sounds like the PLL circuit....... no channel synthesizer will kill the transmit and receive...... bad crystal or IC could be at fault or if someone has attempted to add more channels could also be cause.

SOURCE: an old cobra 29 23 channel Cb that has no audio or key up

This is a typical indication of the finals being blown. Probably have to take it to a shop, but it would be expensive compared to the value of the radio

I just picked up a 99 china cobra ltd st. Tx works on all channels, but no Rx on channels 1-19. Any help pointing me in the right direction would be greatly appreciated.


somebody tampered with internal adjustors seems to me. you can take a screw driver and turn off receive for so many channels but crank it for higher band. It was probably locked on a upper channel for a Friendly chat station say Channel #28. Where they stayed and talked on 1 channel all time. Could be that. Maybe its got broke wires or board on that other set of channels or parts fried, chip bad etc. Get it checked out at CB shop. if you have any knowledge, turn IF to receive and crank up receive inside radio. If don't know anything take to shop..sounds like simple fix to me.

My cb cobra 29 ltd problem is channel 1 is ok but channel 2 not receive


Did you have someone get on channel 2 to see??? Maybe channel 2 was quiet and channel one had better receive or noise.. You never know until you check it with another radio. That is NOT a common issue at all on those radios. Better off doing that test.
