The IF is 17.9 MHz.
So, the formula is:
F carrier = 3(F crystal) + 17.9
or...
F crystal = (F carrier - 17.9) / 3
This works for the VHF-Hi Spirit T&V pager.

While T&V pagers are on my mind,
KC8GRQ, what was the name of the repeater controller that encoded QCII? I obviously forgot.

Are you referring to the variations of the RIC? The ZR320 and ZR340, built by Zetron could do QCII selective signalling, plus generated the PL/DPL for the TX. This complicated matters if you also wanted to add a remote adapter because a basic PTT did not turn on the PL/DPL generator.
