Tnx, Oh, I see, you calibrate the tuning dial by using the Xtal as a
reference
knowing it is at the stated Xtal frequency when the magic eye peaks. I assume
you
use the little knob next to the dial for this tweaking? or do you loosen the
dial
and re-set it according to this calibration?


Just turn the vfo freqency knob to see the zero beat, then lock it.

In ham use you would not usually use the crystal check/set feature, but you
could. The crystal's socket probably would accept an FT243 mounted crystal.
