[aprssig] Balloons abusing our network...sigh

The OpenTracker and Tracker2/Tracker3 series can all switch profiles 
based on altitude.  I usually set up my balloons for one hop below 5000 
feet (some of the terrain around here is > 6000 feet) and direct above 
that.  With the MX145 transmitter the Tracker3 can be set up to transmit 
on different frequencies at different rates, so you can use 144.39 for a 
packet once every minute or two for backup tracking and a separate 
channel for much faster updates.  We haven't had a packaged version with 
the MX145 in a while, though.
