Cobra 2000 GTL Issue

[Raccoon]

Hi everyone, I've got a 5 pin Cobra 2000 GTL that I'm having an issue with . I haven't used it in awhile , so I pulled it out , and wired my D104 Silver Eagle up to it ... and first of all, it's receiving whether I have the mic hooked up to it or not . And second , in order to hear the CB , I have to have the "PA/CB" switch in the "PA" position . If I switch it to the "CB" position , it acts like it's in the "PA" position ... nothing is heard . Remember , this is a 5 pin , I shouldn't be hearing anything without my mic plugged into it .

So does anyone know what's going on with this radio ? It's never done this before , it worked fine the last time I used it .

I think I may have answered my own question .

I've been researching , and I think that the VR12 may be the culprit. Previously my Cobra 2000 was having a mic gain issue . If you turned the mic gain up to around the 10 or 11 o'clock position it would get really wonky when it was keyed up . Now there's no transmit and it has to be in the PA position to receive . I've found a few others that had this same problem ... and they fixed it by replacing VR12 . I just thought you might like an update.

you may be plugged into the pa jack not the speaker jack

No, I made sure that I was plugged into the external speaker jack ... lol

has someone replaced the socket to 4 pin?
maybe someone jumped a couple pins on the mic pcb under the radio. should be deaf with no mic
