[aprssig] Droping WIDEn-N does work!

Thanks Brian!
Yes, actually all we need is a few FIREWALL DIGIS that
are half way between major metro areas to drop WIDEn-N
and that solves everyone's DXQRM problems but lets
WIDEn-N work well in the LAN.  And that FIREWALL can
then add back a LINKn-N so that intentional packets
can go city to city if needed.   de WB4APR, Bob

I dropped WIDEN-N here in NW VT at N1BQ-3 last Spring ... And it has
made a
major difference. I was the "bridge" between the Albany/Saratoga NY LAN
and
the Montreal LAN and was regularly 'passing' WIDEN-Ns that were 4 to 7
hops
with at least 2 hops left after it hit me. The probability of NW VT
APRSers
getting posted to FINDU via the iGate in Montreal more than doubled as
a
result
