Hi there everyone! I am attempting to put channels in a buddies rig and I am having an odd problem, I would sure appreciate your input.

It is a Uniden Washington, MB8719 3 Button Board number PC-385AH.

The one that I have attempted is the method where you isolate pin 10, and connect one wire to pin 10 then the other to ground (SPST).
Also, another SPST to connect pins 11 and 12 (Pins Not Isolated).

I get a lower frequency jump when 11 and 12 are connected, but when I switch pin 10 to ground it just goes lower.

In other words, I can't get any high channels out of it.

I would love to put an EXPO B kit in it, but no-one seems to have one.

I would just do "the_mod" but this rig is not quite in good enough shape for that investment.

I have played with the VCO, and it locks ok but I feel like I am missing something or doing something wrong.

Perhaps if someone has this same rig with the PLL jumped, they might be able to Eyeball it and see how theirs was done.

Thanks again!

I think you have to change the 11.1125 crystal to a 11.3258 crystal
