The APRStt user will show on APRS maps as a simple box symbol
with an overlay byte.  This lets users indicate any one of 36
different overlay characters.  I chose a 9 to imply a mobile.
Though come to think of it, I probably would be using a 7 at
Dayton where I would be carrying around an HT.

APRStt at Dayton will hopefully let one use any DTMF HT to enter
his position at the hamvention and his monitoring frequency.
