Well keep your rate up at 1 minute and 2 hops and monitor voice
alert.  In very sparse areas, the maintenance of a 1 minute rate
with voice alert improves your probability of detecting someone
else in the great expanse of wilderness...  Even it you are not
hitting any digis...

Oh, and that is the advantage of proportional pathing in the

It maintains a 1 minute rate, but only every other packet goes
via 1 hop and only every forth packet goes via 2.  So for
voice-alert proximity detection, you still have a 1 minute local
rate, but your immediate local digi only sees a 2 min rate, and
the 2 hop area only sees a 4 minute rate...
