Mike,
I HAVE looked at this page. I looked at it over a week ago. I put the divider
network of 2 4.7K resistors to pin 13 of the exciter plug and that cured the
problem.
Thank you to all who suggested fixes for this problem.

Thanks for the tip,
I'll try re-seating the flat cable connectors. Already cleaned the multi
turn noisy freq pot with success by drilling a small hole and injecting
suitable contact cleaner / lubricant inside.

Hi Mike,
Excellent information. It's a new pager and it's a two channel system, no cans.
We're the ham guys and have been there for about 5 years, but only as guests.
Yes, there is a non-interference clause, but we do not want to go that route.
We're all on good speaking terms (tower owner,
I've seen this exact situation after a unit was moved. It's probably
even more likely when both parts are from the same vendor. I've seen it
with quick turn parts from ICM, too.
I don't know if it's caused by mechanical stress from aging, or the
addition of contaminant mass to the quartz

Then one day not too long ago it quit running.

Well it looks

Was the shift a drift or a step jump?
If a step jump, you probably have a bad silver mica capacitor.

DCI will do custom designs for special situations, and yours
certainly qualifies.
If the DCI is going on yours, make sure and plan ahead - I was

What it turned out to be was a plate of a silver mica capacitor
coming disconnected internally in the capacitor.
This caused the capacitor to shift to a lower capacitance by the
amount that the plate contributed to the capacitor.
