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

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

Hope this helps and 73,

It would help more if you separated your MHz from KHz. Those are all WW2
tank transmitter frequencies and were for 54 X and 72 X multiplications so
that it could be FM'd. The Army must have loved old Armstrong, they always
used FM even when the well understood capture effect kept killing off their
guys. Same reason the Air Force still can't talk to the ground pounder
unless they stick an AF guy with an AM rig with them on the ground. Sigh
