[Solved] Cobra 140 GTL Takes 3 seconds to "Stabilize" on SSB.

Hello,
I got a couple of Cobra 140 GTL radios that are behaving this same exact way. 1st one has been full recapped. 2nd one has its stock capacitors in it except 2. Both have had the AM regulator changed out to an NTE-152. I did unlock the clarifier on both radios. Removed a leg off D36 and R137, and located the wires on the clarifier and put them to their right spots. You can slide up and down and it follows. What happens is that when you key up, it will take the radio some time to stabilize, about 3 seconds, then it is ok. I notice on AM it takes it a moment for the audio to actually roll in when you key up. Just a bit irritating that when you transmit that it takes it a few seconds so you stabilize. I am listening on in using the 146 GTL, so I sound a bit off up until a few seconds later, then I sound more on frequency. Of course this isnt happening on my other radios like a 146 or the 148 when you key up.

Any help or insight on what might be going on would be greatly appreciated.
 

Yep.... After some sleep, I realized I undid the wrong resistor.... I will put it back and remove R187...... Somehow my mind read it as 137 last night and I was a bit tired... Oops! :) Will report back later...

100% agreed. My next bad decision was to work on the radio at 5AM (Central Time) since I am already up. Allergies are whipping me into shape. Think I will hold off. :)

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
