   Thanks, I'm glad you like it.

   I've just installed !DAO! support on aprs.fi. The new Ham::APRS::FAP 
version should be released in the near future, too. Thanks for the parsing 
code go to Tapio Sokura, OH2KKU.

   Compressed format is parsed correctly, including speed and course (not 
heading).

   Just to clarify: Heading of the vehicle is not transmitted in APRS 
packets, just course. Heading is the direction a person or vehicle is 
facing or pointing, course is the direction of travel. The difference is 
more important for ships and aircraft than a car with the front wheels in 
the middle position. :)
