[aprssig] BALDY APRS Station

[Jim Alles]

I wrote some suggestions on page 11 here<http://www.tapr.org/psr/psr116.pdf>,
and I hope for the day that a callsign-identified mobile station can 'push
around' an object with tactical identifier and the automatic GPS location
of the station.

My approach would be to separate the address (callsign) from the
information, since they tend to spontaneously combust when brought together
;)

Peace,
Jim A.
