Ok, gonna sound stupid here. The xtal that originally came with the unit was
set for normal frequency range. Does everything have to be redone when you go
with a high side xtal? At this point it will not receive even with a 5 watt ht
next to it, aside the 0 dBm my service monitor gives it.

You did re-tune the oscillator section, didn't you?

Thanks Chuck, that is what they sent me, so your math is just fine. Then
there must be something I am missing. I can take one of the old xtals and they
work out just fine, so I know the receivers are working. Might I ask what the
formula you used was? It's been a long time since I have calculated a crystal
freq. so just need the formula configuration.

If my hasty math is correct:
144.81 low side = 14.845555
144.81 high side = 17.334444
434.875 low side = 16.39537
434.875 high side = 16.521296
