[aprssig] A/N game Football Tracking Underway! & APRN

This sounds like an excellent idea, especially given the impressive
distance travelled
by the runners (and hams).  This would be a perfect exercise to
test/practice APRN
during a large event.  There aren't that many events where hams are going over a
long distance and where tracking with APRS + visualizing what's
happening with SSTV
is both useful and fun!

By the way I was wondering if something interesting could be done with
too.  I think that geotagging a QSO (voice or image) with APRS
position packets (or
even other data packets) is very useful in general.

Unlike with APRN, APRS + ATV would require two different frequencies.
144.390 could
be used for position packets because everybody is listening to it already.

Packets could also include something like: "ATV EVENT! TUNE TO CH57 421.25" or
something like that to alert all hams around that they can see the ATV
on their TV by tuning to analog cable channel 57 (or 58, 59, 60) and
pointing their
antenna at the ATV transmitter (they get the position in the packets too, so
if the transmitter is ATV mobile or ATV portable, this will be even
more useful).

The very very advanced hams could use a rotor and track the mobile ATV station
automatically based on the position packets they receive (some easy programming
and interfacing would be required).  Since ATV is usually low power,
good aiming of
the receiver antenna might actually be very very useful.

Just an idea...  I hope to try out ATV in the coming weeks...
