Cobra 142 tx problem

have you checked the finals? or your audio amp ? very easy to repair .

I recently got a 142 GTL off ebay and it's really nice, was bone stock except someone had put a 2SC1969 final transistor in it, I think it came with a 2SC2312 originally. Nothing else had been messed with.

2 things I did find wrong with it, though.... the squelch knob is worn out, the pot is about to fall apart, so I will be robbing a pot from another radio in the junk pile here soon, it hasn't completely fallen out of the radio yet, but it's definately on it's way. The other thing is the Dynamike pot... It has 2 spots in it, that don't work so well. Cuts my audio back or completlely out, so I have to avoid those 2 spots. Will be robbing another pot from another old radio soon to fix that as well. I already cleaned the pots with contact cleaner, they barely worked at all when i got it, I guess the radio sat up for a LONG time in the closet as it looks brand new still.

Now that I have done a good tune up on it, it talks like a big radio, I really like it, and have had nothing but "amazing" reports on it so guess I got a good deal. Awesome little radio. I prefer the receive on it about 5:1 over my RCI 2950 with the Scottky diode mods and all that, the Cobra still has a cleaner stronger receive.

As for your particular radio, sounds like the final is bad, or something went wrong with the AM Carrier pot mod they mounted on the side of the cabinet for your vari-key function. There are a couple different ways to do it, I suspect they just removed the pot from the main board and ran the wires over from the holes to the pot mounted on the side of the radio. Probably cost them $2 and maybe 20 minutes time they probably charged you $50-$100.

The stock fibal for that radio is the 2sc1969. Ben
