One possible problem might be when flying in places like dry lake beds.
If you're flying at say 500 feet will there always be a ham within
range to get the aprs report? At 100 MPH you might cover a lot of
potential ground without an aprs report getting received by someone.
The satellite unit can see the vast majority of Earth's surface from
space. But, I agree, the satellite method relies on that little
G-Switch to indicate trouble...

Basically the APRS tracker is a small gps receiver / 2M ham
transmitter which sends digital position signals to nearby digital ham
station, which in turn send the info to internet servers and you can
see your last reported position on google (or other) maps on sites
like www.findu.com. It is simplicity itself for end user.

I also suggest you invest $15/yr in a MyPlanexxx.com website where
your relatives (and FAA) could easily click to link to findu.com with
google map to see your location.

If some of you want the finished product I am willing to put it
together for you - you pay for expenses and labor - see

But you still need a ham license, which is easy to get.

APRS is superior to 406 unit since it is real time and does not depend
on "going off" in a crash.

You can build an APRS tracker for about $250. A basic ham license is easy
to get.

Bring a Pilot to School Day:

Can you explain how this works, like we're a class of 8th graders? We'll,
7th graders, really. See, 8th grade just started, but we're still reviewing
from last year...
