Cobra 21 Sqeal

do you use a power mic?

 

The mic would be my first guess, too... esp. if you leave the talkback turned on.

Noise cancelling mics are worth the money, for sure.

 

if the power mic is turned to high its probably the cause....

i think if the talk back was on he would know it squeals as well.... unless the talk back speaker isnt working...

 

could be a short in the mic being a electronic switching system, a failed part, SWR Mismatch, corrosion on the board itself .

my sugguestion take it to a repair shop that works on radios and doesnt rip you off.

Good Luck !

 

ha i just re read the post.... yeah hes /\ right you probably wanna get the whole thing checked out, i mean old electronics dont work forever... but who knows it could be something unrelated to the condition of the radio, or a mic... it could be the antenna set up or a ground problem or something. first step make sure all is well with the radio....

 

rf gain could possibley be to high try adjusting down little by little

 

I have a Cobra 21 as well. It died on me this last week. I can listen but if I try to talk it just comes over the FM radio and no one hears me. Got a lot of use out of it for a free radio.


Guess I'll just buy a new radio in a week or two.
