My Cobra has started acting funny. During a key down, I can hear a clicking noise. The background static is pulsing. And just noticed that I have receive even when the Mic is unplugged. Just noticed this after moving my Antron99 on a taller push pole. Had .5 swr before, now I have a 1.8 swr. Checked coax before raising mast and it was good. Any help would be appreciated.

Your radio is Electronic switching. I cannot remember. One of the PNP transistors

is the transistor that controls switching back and forth. Probably that.
