Anytime someone can use a full callsign and follow it up with a 3 digit 
suffix, the APRStt server needs to be remembering the original to match 
against for the shortcuts.  That's the part that I was indicating a DB 
(or lookup table or some-such) would be necessary and possibly a 
challenge for resource-constrained platforms, especially if the 
shortcuts are valid for 30 minutes or so.
