Boy, it's REALLY clear here! <G>

As a comparison, my ALOHA circle runs about 200 miles most days,
IF I elect to see the digis in New Mexico. if I exclude the digis, I can't
even get UI-ALOHA to generate an ALOHA circle, there are too few stations
out this way.
My stats currently show:
16 mobile stations
3 wx stations
7 home stations
17 digi stations

Wow, that's a LOT. Where do they come from? Nevada, Utah,
Colorado, or maybe all of these plus more?

But the real problem isn't allowing me to use 5 hops, it's that I
don't see anybody unless they use AT LEAST 3 hops, and at three hops it
still isn't reliable.
Perhaps I should add the following statement to my status text:
PLEASE ADD CAPTAN,FTSUMN,MELROZ TO YOUR PATH STATEMENT.
Just a thought...
