[aprssig] temporary APRS setup

[Mark Conner]

 Hi Steven,

Do you plan to chase the payload to the landing?  Once your payload is off
the ground, line-of-sight propagation will be excellent.  We've used a VX-1R
in the past with no trouble receiving data for 100 mi or more, as long as it
was line of sight.  This was with a whip antenna on the payload (minimal
ground plane) and mag-mounts on the chase vehicle.

Any I-gate that is line-of-sight will pick it up too.
