Question about Cobra 18 Wx St Ii Mobile Cb Radio
I changed mics, tried three different antennas, sent it back to Cobra twice and they say there is nothing wrong with it. I used my swr meter on it and went to a professional and had him check the swr's.
There is a relay in side of the cb that might be sticking. The problem is that this situation might be environmental. You say that you sent it back to Cobra twice for repairs. I think that the place you are sending it to differs enough environmentally so that the problem does not manifest itself. You can test this by exposing the unit to different temperatures, to determine if the internal relay is sensitive to variations in temperatures.
If you do find that the relay has become tempurature sensitive, you can order the part from Cobra, or strangly enough from Radio Shack, since they do carry the same part just by a different part.
I hope this helps,
