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.

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.
