[aprssig] APRS Calling

There's something to be said about that. With my VX-8R, I can speak to
or text my ham friends, see if they are around (beacons) and check the
weather (APRS weather stations). I can see broadcasts from other hams,
aka bulletins. All of this is with no infrastructure beyond the APRS
nodes themselves. All we need now is for the manufactures to start
getting more adventurous about the packaging and user interfaces. I'd
love to see an APRS device with a slider or touch screen form factor.

Best,
