Further to my earlier, now that I have my manual, notes and coffee in 
front of me, each band has a crystal and series inductor on the XTAL Osc 
& L.O. board, page 4-14 & 4-15 in the manual.    The inductors can be 
tweaked for each band.  These are L12 - L21.

The BFO alignment procedure is on page 4-23 and 4-24.  This alignment 
must be done first and in the order stated in the manual.

I usually allow the radio to be at operating temperature for about an 
hour before starting adjustments.

Just correcting one band or frequency is ill advised as there are many 
inter-related adjustments.
