K9APRS foot mobile in New Orleans just got a posit out!

With exceeding luck, his packet digipeated with one-hop via the New Orleans
W5UK-9 digi just got out via a lucky shot to an IGate over 160 miles away!

http://www.findu.com/cgi-bin/find.cgi?call=K9APR-7

Here was his D7 position report (within .2 mi of the digi):
  K9APR-7>2YUT3X,W5UK-9*,qAo,AA5ED-10:`vZ1l [/>

Notice that his packet was heard via the one-hop W5UK-9 digi and then via
an IGate over 160 miles away! (AA5ED-10). This confirms that there are
stations in the downtown area being seen locally by the W5UK-9 one-hop
digi, but nothing is getting beyond that because that digi truncates all
packets to one hop and does callsign substitution, thus canceling the rest
of his original path.  There is not an IGate that can hear that digi
direct.  We need one.

But that W5UK-9 digi is at 600 feet! in downtown New Orleans.  It can be
heard direct over 60 miles away.  If t here is anyone with an IGate,
not  involved in emergency response that can simply point a beam towards
New Orleans and get those packets from that digi after their one-hop, then
that Igate will re-constitute APRS connetctivity to downtown New Orleans.

Good luck!

Please pass this to whoever might be trying to re-constitute the APRS
network in New Orleans:

It can be done easily!

The main APRS digipeater in New Orleans is working fine at 600 feet and
covering over 5000 square miles! BUT, it is a rare one-hop-only digi.  This
means that although the beacons from that digi are making it to the global
APRS system via 2 hops, any APRS mobiles or traffic originated via that
digipeater are not making it out (because they are being limited to one hop
only).

All that is needed is someone with an APRS IGate software within 90 miles
of  New Orleans to point a beam at the W5UK-9 digi in downtown so that his
IGate can hear the digi direct.  WIth this one station, it will tie-in the
entire New Orleans network to the global APRS system to completely restore
connectivity.

Locals may not be noticing this problem.  Yes, they are SEEING the W5UK-9
digi on their systems, but that is because that digi is sending out its OWN
ID beacons via 2 hops, but it can only send out the packets from its USERS
as one-hop.

The nearest IGates in Alabama and Baton Rouge are 2 hops away.  THus
nothing is getting out of New Orleans except only the DIGI's beacons.

Hope you can get this to someone who maybe has the ability to re-establish
the APRS conectivity out of New Orleans.
