Yep.  Appreciate the correction Cap!  There are getting to be VERY
few places where three hops are needed.  Perhaps a _very_ rural
area not served well by high digipeaters where one must radiate down
some canyons to get out to civilization or something...  We have a
few such places in our area, but you have to go up into the
mountains to find them.  Chances are you just won't get out at all
from there no matter how many hops you choose.  Might be better to
rely on ISS in that case.  hi hi (or high high?)

And I just reported on another list that a station across WA state
from me was appearing way over here on the west side, apparently
running a WIDE3-3 path from an igate.

A path of "WIDE2-2" or "WIDE1-1,WIDE2-1" (for a mobile) appears to
really do the trick these days, at least in places where the new
WIDEn-N paradism has been implemented.  The NWAPRS system is one of
those.

I did some experiments over my normal commute path a year or so ago
with running WIDE2-2 from the mobile.  WIDE1-1,WIDE2-1 worked MUCH
better for me 'cuz I got that boost from the fill-in stations.
