If the crystals are the old WW2 crystals that are about an inch
square, the frequency is determined as follows:

If the Channel is a 2 digit number, divide the marked frequency by 54
to obtain the fundamental frequency:

Channel 32
Marked Frequency 32.2 Mc
Fundamental Frequency 32.2/54 = 429.630 MHz


The new math??? Perhaps 596.296 Kc




If the Channel is a 3 digit number, divide the marked frequency by 72
to obtain the fundamental frequency:

Chhannel 381
Marked Frequency 38.1 Mc
Fundamental Frequency 38.1/72 = 529.166 MHz



Ditto, but Kc
73, Steve, K9DCI


Hope this helps and 73,
