[Boatanchors] Need Xtal Frequency Conversion Formula

[peter markavage]

Depends on the IF that the oscillator and mixer are looking into. Could
be crystal frequency plus the IF or crystal frequency minus the IF.
Depend on how they designed the mixer. There could also be a divide by
factor that you might have to consider.
