That's the whole point --- you can't have stations listening to vast 
areas in SoCal and then digipeating since there are just too many users 
here.  All you wind up doing is listening to multiple simultaneous users 
clobbering each other.  If the range is limited, you are much more 
likely to hear only 1 station at a time.

Lots of low level home RELAY-only/Igate combos, each with limited 
coverage,  would allow cellular-style simultaneous reuse of the 144.39 
channel all over SoCal without blasting every packet over 1/3 of the 
state.

Which immediately again blows the Aloha limit of 50-60 stations.  Given 
the population pressure, nothing in SoCal should be getting digipeated 
more than about 20-25 miles tops.    More Igates so that you only need 
one digi hop,   not alternate digi schemes to go hundreds of miles,  is 
the solution.
