I have a VHF Minitor II RF board and I need to find out what frequency it is. The only crystal (Y161) has the following info on it.

KXN6300 (maybe 6800, hard to read)
45773.33
Motorola
9028

Can someone tel me what the freq it is, and also tall me how to do if for myself for future reference?

Thanks!
David

Your cyrstal is for 155.220. The formula for a Minitor II crystal is the Operating frequency (155.220) - 17.9 divided by 3 = 45.77333

Thanks Andy, I really appreciate the info. I thought this pager may be from Rockingham CO. NC. I will probably contact you by email in a few days. I need some Minitor II tone reeds and also have a Maxon radio I need programmed. I have some VHF Syntors for sale you might be interested in as well.

Possibly from Rockingham, Guilford or Randolph, they were all on 155.220 several years ago.
