Hi folks.. Have a Regency HR-2A that I want to re-crystal for packet
use, but don't have the manual, and therefore do not have the formula
for calculating the frequency of the receive and transmit crystals for
desired frequency of operation. Could anyone out there help with this
info? Hamfest coming up this weekend and I'd like to shop for
crystals. Also, is there a .PDF of the manual available anywhere?

The receiver is the standard of desired frequency - 10.7 mhz and then devide
by 3. This gives you a frequecny of about 45 mhz for the crystal. The
transmitt frequency is devided by 24 if you have a HR2A,212 or MS . This is
about 6 mhz. If you have a HR2B then you devide by 18.

Not sure if you will have any luck for the crystals for packet as that is
usually below 146 mhz and the old Regencys were made before anythig bleow
146 mhz was in common use.
