Question about Cobra 29 LTD CB Radio
When you turn the raido on the needle swings the led comes on and then the whole thing shuts off it has ben in the same set up and always talked good ive got a 4 ft fiberglass whip on the roof of my truck and its about 12ft off the ground total i have not changed the set up but i did clip (D11) or (D12) not sure but the raido woorked good for about a year and would out talk most high $ raidos need help
Well I hope you didn't clip D12. D11 makes sense to me. If you clip that you are disabling the AMC, automatic modulation circuit. This will allow the radio to modulate at full modulation all the time, which isn't always good. You can over driver your final and possibly blow it.
Most of the time you can just turn up VR4. thats the AMC adjustment. It will raise your modulation to the max but will not over modulate it.
You probably blew the final and or more components as well. Your going to have to take it to a radio tech. This is no simple fix.
