   Instead of filtering by prefix, you might want to set APRS-IS filters by 
coordinates / area (see http://www.aprs-is.net/javAPRSFilter.aspx - Area 

   It might be close to impossible to get everyone using proper callsigns 
as the source (from) callsign, as using tactical callsigns is pretty

packets on the APRS-IS are originated by licensed amateurs.
