To determine the xtal frequency you need to look at the rig's conversion
scheme, and have your calculator in hand.
To put my KWM-1 on 17 meters I determined that an 11.034 Mc rock would be
doubled to 22.068 Mc. Then, subtracting 4 Mc would yield tuning at 18.068
Mc. Subtracting 3.9 Mc would yield 18.168 Mc.
Wishing to use what I had on hand (namely a KWM-2A military xtal pack), I
deployed a KWM-2A's 11.0775 Mc crystal. That delivers coverage in my KWM-1
from 18.14 through 18.168 Mc. The dial reads from 085 to 013. The dial at
0.0 corresponds to 18.153 Mc.
