Yes, no.  What I mean is that every digi should have a separate
local input for whoever is local and wants to use it as a priority
input to the digi...  LOCAL users should get priority..

But it cant.  It is physically impossible to have more than 
stattistically about 50 to 60 users on a single 144.39 channel
anywhere....  COunt up the total packets transmitted and it
comes out to 100% solid channel...  that is why all efforts
in APRS these days should focus on limiting out-of-area
packets from too far away from QRMing the local network.

>More "future concepts"... let's move to a duplex system. 

Yes, that is exactly what we are proposing with the alternate
local input channel (144.99 if available in the area)...

I think we are in agreement, just saying it a little differently 
I guess..
thanks
Bob
