I'm trying to help a friend who is in AZ to jack up his yard sale score.
A cobra 140 GTL, I gather that this rig is the same as a 142.

So, sense it's not here, I can't just figure it out by looking at it.

What do you do, specifically to drop the carrier on AM and get forward power on AM.

The goal is to super mod this rig. So any help would be great. I'm sure it's easy, I just don't have it here in front of me. My friend is a experienced radio operator, so decant directions will get the job done.

Thanks.

Well, here's the scoop. You've all been bad, so all you get for xmas is snowman poop.

No just kiddin'

Change C90 to a 3.3uf or 4.7uf. RemoveC119, and run a 1000uf cap from positive side of C119's position to the base of TR34, with the positive side of the 1000uf cap going to the base of TR34. Remove R186.
