Several people suggested that the switch on the end of
the crystal oscillator module was for switching in pre-amps
based on the band.  This is probably as good as explanation
as any.  I did attempt to see which bands were grouped
together by the way the switch terminals are jumpered
together and came up with the following:

0-1  Mc
2-8
9-13
14-16
17-20
21
22
23-26
27-28
29-31

I can send a .jpg of the switch itself should anyone be
interested.

thanks,
Phil
