Nope. He meant Kc. These are WWII rocks that were marked in Mc.

Ah the good old days when when we had kilomegacycles per second.

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,
