> Telemetry support on the OpenTracker has been merged into the 
> firmware release.  If you enable telemetry output, you'll get an 
APRS format
> telemetry report with:
> Temperature (+/- 2C, from onboard sensor)
> Supply voltage (accurate to about 0.1V)
> External analog input
> Digital counter (continuous count or reset after transmit)
> HDOP reading reported by GPS
> Jumper / digital input state
> Config profile in use
> At Bob's suggestion it now reports a proper sequence number.  The
> temperature and voltage sensors can be removed if you want to use 
> inputs for something else.  This release also allows you to 
configure the
> tracker to transmit if it loses GPS lock - it'll add a NOFIX flag in 
> comment to let you know the position might not be valid.  This 
should be
> particularly useful for balloon users that might lose the GPS on 
landing, or
> have it freeze up in flight.
