[aprssig] New n-N success in North Carolina

I don't know an answer for the dumb trackers out there.  I use a D700
and a D7 and change my path as I go.  I don't think there is a single
path out there that will work everywhere because everywhere is
different.  You can't go to the Midwest with the same path that you
would use in NC.  If you were running up and down I-95, then the
once-proposed 95LNKn-N would work with probably a RELAY in front of
it if you do venture off the I-95 corridor...  BUT, that won't work
now that work has ceased with that project.

Not being that familiar with the dumb trackers can't you reprogram
them with a laptop?  I know it would be hard to reprogram it every
100 miles...  Maybe use RELAY,WIDE?
