I'd have to have multiple units since scanning is not a favored path.  I
have a scanner which is why I'm on a quest for individual receivers.  :-)

I only care about AM since that's what aircraft use.  FM is covered by the
ham equipment on hand so it's not an issue.

This seems to be an issue.  While the individual frequencies are several MCs
apart, I never really looked at the products of mixing them together - or at
least the LO frequencies.  Each front end would be in its own individual box
with a common antenna connection at one end and a common IF out at the
other, grouped together within each band.  

The way it's going now, I may as well just use my A.R.C. equipment for VHF
for now and noodle around for UHF equipment to go with it.  A set of
AN/ARC-73 receivers with the frequencies hardwired at the connectors would
be nice for VHF but that has about as much chance of happening as my
performing neurosurgery.  Successfully.
