FYI Here is the socket and plug for the Wilson WR-500 Rotator https://www.amazon.com/dp/B0BZV8QHC7?tag=worradfor-20 GX25A8P for the plug GX25B8S for the socket

Well the controller i was using in the testing is the G-800SDX and the rotator's are the 6 pin version's, I also noted in my testing that the G-800S controller spin the 2) G-800 rotator's the same speed, But the G-800SDX controller would spin them at slower speed's one way. The SDX and the DXA...

Now this Pace sidetalk 1000B is the 23 channel xtal matrix version. Anyone noticed the discrepancies between the the original Pace 1000M-1000B service manual and the sam's vol 94 and 104? C-247 to C-250 adjustments are listed different in each version in the synthesizer alignment, and each...

I have a 40 channel Pace Sidetalk 1000B(C) with the NDC49913 PLL in it, Very mysterious set up with a separate PLL board. I have the sam's book's for each radio that uses that pll and the closest thing is the Craig L231 that i can figure out, Now what's going on is the PLL isn't locking. I have...

try these,

Hey Brandon. In post #1 i mentioned i did pull the original 11.325 Xtal and it was out of freq, I purchased a new 11.3258 xtal from 6 star on e-bay, So trying a new xtal was already done.

The other 142GTL is one from the same customer that has a channel switch with added xtal's that is a tuned and working unit. In the mystery of why the 2nd 142GTL wasn't tuning properly i did notice that the working 142 had a choke on D-20? No idea why but i did pull it and put it in the non...

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 adventure continues. I original replaced red 20Pf CT3 with a yellow 40Pf cap, It won't come in tune, I pulled it and installed a blue 5Pf one, same thing, I pulled the blue and installed a brown 60Pf one, Same situation. I pulled another CT1 or 2 off another 142GTL board and installed it...

Hey AS. Yes there is a place for C-132 and in my previous messages i did install a 10Pf Cap there it's marked on the silk screen with no difference in the CT3 calibration, I was referring to the link in Secret CB that said to remove CT3 and C-132 and why it was suggested. I did remove CT3 before...

Looking at this article from CB Trick's. Secret CB Vol 8 pages 35-37. It's weird that it mention's removing CT3 and C-132, This current 142GTL doesn't have a C-132

There's alot of pieces part's between the clarifier circuit, D37 and TP1 to turn over the turnup truck. One thing i see as well is the IC1 VCO-Mixer list in the sam's book is a UH1C007 and what's in it is a UH1C070, I just pulled C-66 that is a 10 VDC cap to dig out more sony bond i missed...

Any shot's in the dark are welcome
