Bryan and Bill,
,
Wow, great thinking.  Does the KPC-9612 then transparenltly operate KA node
across both ports?
Then you are right, this is the way to go.  Now, which way...  Im still then
leaning for 2m for the long haul between nodes, and then users come in on
UHF because they are closer and can use beams on UHF?

What Brian said!!

If you do use the KPC-9612 you'll have a second 1200 baud port.  Hook that
to a UHF radio for user access.

I'd argue that the 'easy' technique of mixing node to node and user traffic
on the same node in the Legacy packet system was responsible for poor
performance and thus disenchantment and downfall of the whole system.
