If we go with UHF, just remember we'll have to deploy some receiving
stations who can gate the data to the APRS-IS for us.  I kind of like the
UHF idea, but am open to discussion of either.

Dave,

 

Yesterday I ran a battery life test on the Beeline BLGPS 2M tracker, powered
by a 7.4v 1800mAh lithium battery.  Nominal output was set to 5W with
transmissions every minute.  After nearly ten hours the output power was
still over 5W.  I haven't yet tested the 70CM version - I have to check to
see if I have the correct battery.

 

The 2M BLGPS weighs 45 grams and the battery is 74 grams.

 

73,

 

Bob  W0BUX
