Question about Cobra 29 LTD CB Radio
Blown RF Transistor mostly due to running a high SWR(bad antenna)
Posted on Jan 30, 2010
I am assuming you have called out for a radio check and not gotten a reply, or even better tested it with friends radio. Just because the meter doesn't mover doesn't mean that its not transmitting.
So as long as you tested it with another radio, and it is not transmitting it could be any number of things. If you have never had antenna tuned so the swr is low, or your swr was high for a long time, your final transistor is most likely blown.
TX switching transistor could be blown, trace could be gummed up.
If your ant light is coming on, the is a problem with your antenna. Could be disconnected, and that can lead to a blown final.
At any rate, your problem most likely requires a tech. Take it to a repair shop.
