Need a small APRS gizmo for remote telemetry?

The pocket tracker which combines a TinyTrak
and a small 144.39 transmitter and a 9v battery
into a shirt pocket device (fits in an Altoids can)
is ideal.

Of course, it only processes GPS data, but wait!

For other purposes, remember that GPS data is
just numbers and there is nothing that says it
has to mean LAT/LONG.  So if you want to have
a quick way to get a unique telemetry system on
the air, just have your little project output a GPS
NMEA string but let the 13 or more digits mean
whatever you want.  THen decode them on the
other end...

Anyway, just a quick way to get some unique
telemetry on the air in a small off-the-shelf package...
