If you want to further analyze the Mic-E packets, see the details at 
http://aprs.org/aprs12/mic-e-types.txt and 
http://www.aprs.org/aprs12/mic-e-examples.txt but beware of the added or 
removed trailing space issue when it comes to detecting Yaesu VX-8's or 
otherwise looking at the "last" character of a Mic-E packet.  The 
character you're looking for MIGHT be before a trailing space that was 
added along the way or it might BE a trailing space that was improperly 
removed.

PS.  What's a HinzTec anyfrog?  Looks like another one to be added to 
the APRSISCE/32 platform detector.
