Yes, that is an ideal application for APRStt. Does anyone want to take a crack at the algorithm? I think it would be very easy in the flea market, maybe only a few rules. IN doors, it would take a lot of rules inside each pavilion. But it can be done! ANyone?
Once we finish APRStt, then it should eventually have this flixibility. For marathons, it can be simply a table of 26 entries. But for something like Hamvention, it wouild take several rules.

>> Remember, this year at Dayton, there will be an APRStt (Touchtone) gateway. Meaning anyone with any old HT with a DTMF keypad can report his position anywhere at Hamvention (to nearest 100 feet) using only a single X and Y digit (00 to 99) see the map on

The B key means a POSIT, the X and Y digits are from the map grid on the web page above, and # marks the end of data.
