   I agree.  That's the goal.

     Agreed.  Within RF range of the pockettrackers especially.

     I disagree.  Don't crowd .39 with more traffic.  Set up a .99 input 
port on the igate instead.  If you want to get more complete coverage, add 
input ports on all the 2m simplex freqs, looking for mic-e packets as

   When channel loading gets near saturation, the digis should be turned 
OFF, and allow the igates to send the traffic OUT of the area, but not add 
congestion by bringing any traffic into the area.

   I still think that digis should be smarter.  They should be sensitive to 
the position in the packet, and should refuse to digi any packet that 
originates outside of the 'service area' as defined by the sysop.  With a 
little more work, this 'service area' could be variable, depending on the 
current channel loading.  As the channel gets busier, the digi gets more 
provincial about what it chooses to repeat.
   With this type of smart digi, we could truly have a universal path spec. 
Each packet would travel as far as the network would allow, and be 
truncated when it got to an already congested area.
