Well,  thank you for that,  Bob,  and all the others who have
responded.

I will presume that the original design was as we now have the 
entire Corsair series of radios.  And the deliberate reason to
avoid hetrodynes from the 9 mHz IF sure makes sense.  Trying
to come up with a workable frequency plan for a multi-band
radio can be a challenging problem to avoid all the undesirable
higher order hetrodynes,  hi!  And one way to kill one that just
won't go away,  is to use the IF on the other side of the LO !
