Dick,

BTW, that "Sync Xtal Osc" hole is for aligning the big rotary switch inside 
the crystal oscillator deck.  To adjust it, you loosen the gear clamp on the 
front of the crystal deck (or, more formally the gear in the RF deck that 
drives the rotary switch) and then you can rotate the switch to the proper 
switch location for the current band.  You shouldn't have to do that unless 
you've taken that part of the RF or crystal deck apart.

73,
Barry
