[aprssig] Mea Culpa, or Yesterday's Adventure in Ballooning

Yesterday I was helping out a high school group with a balloon
release/chase/recovery over Georgia, which included flying an APRS
tracker I built with callsign KY7DR-3.
Due to as of yet unknown reasons it suffered a couple bouts of packet
diarrhea and was spewing packets nearly constantly for a while during
ascent and a while during descent. At altitude it appeared to be
behaving (packet timing wise), but wasn't getting useful GPS data. It
was configured to use a path of WIDE1-1,WIDE2-1 at low altitudes and no
path at all at high altitudes (>10k feet), but I'll still reviewing data
to determine if that worked as intended.
I'll report more if/when I learn anything useful about why things didn't
work as intended. I have grabbed a bunch of raw packets via aprs.fi to
review, and I may get some live-off-the-air data from another ham in our
Sorry for spamming the network in the US southeast.
It did work well enough on descent for us to recover the payload.
