Sometimes three simultaneously - usually the R-390 on the channel I'm in
QSO on - the R-388 to tune around and 'spot' with, and the multi-band WWV
reciever that I use to get a quick snapshot of average propagation
conditions across the HF band.

I have a couple of 75-ohm video punch-n-crunch switchers, but that
doesn't allow multiple recievers, nor does it isolate the 'feed' from the
radios' input networks.

Agreed - that's why I want a Coupler, not a Splitter.

You might want to do a bit of looking into the subject of active
couplers - only the cheapest and incompetently designed units would fall
under your surmision, IMHO.
