Hey Kop.
The clarifier is at 12 O'Clock when i try and adjust CT3 and i can not get it to 34.987500 by moving the clarifier.
So i was experimenting with this NTE612 that i had soldered to the board and i thought of this, I took a 1Pf cap and added it in series to the NTE612 varactor diode and the CT1 value dropped from the 34.987500. I threw in a 3Pf and it dropped more, So i macgyvered the 3Pf cap to the original D-37 varactor diode in Parallel and tested and i got it to the 34.987500, I then adjusted the lsb and am and now it's dead keying on the proper frequency instead of being 5Hz off.
I then checked the unlocked transmit and it slides 2Hz both way's? Not as much as i would want, I did test the other 142GTL and it slides down 5Hz and up 2Hz, I do have some of the 5.6Uh chokes all the clarifier mod's i read to put in parallel with the D-37 varactor diode,
I'll give the choke a shot and with it, the 3Pf cap and the varactor diode and see what comes up. It may not be purdy, But as long as it work's rite.
One thing i did think of would be to find some lower or higher Pf Varactor Diodes and eliminate the 3Pf cap in parallel i put on D-37, Just a thought.
