Wow great find! Uber-cool stuff.
But, microwave is Line-of-Site and don't think it can be deployed in an
emergency situation.
Thus I was thinking a lower frequency one that anyone can purchase ( as
in License and money ) and deploy with lower power need (thinking solar
etc ) thus GMRS radios at UHF 462.550MHz to 467.725MHz so with a
repeater can go up to around 20 miles.
Best would be 2 meters with repeaters (144.000 Mhz to 148.000 MHz) But
back down to 1200Bps or less.
BTW Packet Radio on 2m is limited to the 149.900 MHz - 145.100 MHz range:

Last I used packet (long ago), I remember the frequencies I used were
typically staggered by 20 kHz: 145.01, 145.03, 145.05, 145.07. Those
are the specific frequencies for Packet I remember using.
With good repeater maybe 100 miles over flat land. Then down to super
slow SSB and AM with 27Mhz ( old CD radio ) but really long distances
and no longer line of site.
2m also has a SSB mode, by the way. It's useful, but not all of the 2m
rigs support SSB or CW modes.
