Thank's Dave, As soon as i wrap up this hand wired Tram D-201, I'll get back on this Magnum

So.... I managed to adjust L19, L20 and L21 and successfully got a stable 3.20 VDC, VCO volt's at the bare lead of R933 (TP2) on all modes. BUT when i connect my freq counter to the top bare lead of R74 (TP3) and adjust L19. L20 and L21, I cant achieve the spec listed (PLL Offset Oscillator) And...

Ok For shit's and giggles. C91 in this Magnum S9 is listed to be a 390 Pf disk cap. I removed C91 (Measured 414 Pf) and installed a 100 Pf Disk cap (measured 101 Pf) and ran the radio and it's still loosing VCO voltage, After installing the 100Pf C91, i did have to readjust L17 to speck.

The Stryker's are about the same that i see now, Dave, hope you find this out for me. Thank's Scott

I replyed.

I'm a Antenna Rotator rebuilder looking to buy rotator cores and controller's, I sell rebuilt antenna rotator's, good working controller's and some part's, Contact me for any thing antenna rotator related,

Year old post, Dirty or broken contact on one of the end of rotation switches or a broken wire to or inside the rotator.

Any Magnum S-9 expert's out there, I have one that loses vco voltage after it warm's up some, I can use a infrared camera and don't see any hot spot's. I already recapped the radio and replaced TR-51, The radio was doing this before the recap job. Also when i loose VCO voltage, in USB the VCO...

Hey Dave, Good luck with your S-9. That's the reason i made the tester to check out all the element's. I got burned on a hygain 5, modal 2705 channel display. After finding a display and installing the display, i found out the display wasn't the problem. The resistor oray was fubar, I...

I also have a Magnum S-9 display problem. The 1st LED segment's E and G are dim. Here's a video of a display tester i made out of a Bread Board, some dip switches and a 2 cell, AA battery to power the led's. Now to find a P/N for the display's.

Watch this video 1st. Watch this video 2nd. Watch this video 3rd. and here is the fix. Watch this video last.

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...
