It's pretty hard to get a good solid vertical dimension reading.
There's a fair amount of "jitter". The best way is to continually read
your altitude, and if the new altitude reading is greater than the
last, save the new value. That way you'll always keep your max
altitude reading at hand. Then, once you have significantly dropped
altitude, you can send a report with the saved maximum altitude, or
you could just constantly report the maximum saved altitude in the
We worked with Jason at RPC Electronics to develop the RTrak HAB, but
it's still not my ultimate flight payload. I want to have a receiver
on board as well as a transmitter. I want to have the functionality of
the OT3, with the scripting engine onboard, and the ability to send
commands up to the payload.
One thing that would be very handy would be to have the payload enable
the SQUAWK command once it gets below 1000 metres ASL. Sometimes it
can be hard to get a good copy on the packet, but with the SQUAWK
command, you get an alternating tone on your TX frequency. This makes
it very easy to distinguish the payload transmissions by ear, and you
can have the tones on for a user defined period, which would
facilitate easy DF triangulation if need be.
The payload landed in an area where the trees had just been cleared,
about 300 metres south of TWP RD 562 on the 1/2 mile property line
between RNG RD 63 and RNG RD 62, right about where the creek goes

The callsigns are still in the link sent previously... balloon payload
is probably already back in Edmonton by now.
