[aprssig] KB3TAN-11 APRS Usage

Do we know what this balloon project was or who was involved? Don't recall
seeing any announcements on the lists. These maps will be good to show
people exactly how much a geographic area one can affect by improper path
selection. How often were the packets going out? From the looks of the track
if was pretty aggressive.

The illustration of just how far the direct packets reach should be also
quite enlightening to those who think they need an extra hop in their path
just to make sure they get to the internet.....

I've posted the APRS Infrastructure Utilization graphs from today's 
flight of KB3TAN-11 to

http://ldeffenb.dnsalias.net.nyud.net/Tracking/Balloons/KB3TAN-11* 
(Trailing * required).

These graphs show only those stations involved in packets gated to 
APRS-IS and not all of the actual RF traffic caused by this balloon's 
WIDE1-1,WIDE2-2,WIDE1-1 path.  The raw packets at 
http://aprs.fi/?c=raw&call=KB3TAN-11 show quite well the redundant 
delivery of delayed packets caused by the far-flung RF beaconing of this 
station.
