Just as HGX is the National Weather service designator for 
Houston/Galveston Texas radar, HWX seems to be associated with Hawaii.

The latitude sure looks invalid and the longitude cuts through West 
Texas... sorta far from Hawaii!

"APT" would be the start of a TinyTrak tracker TOCALL but the whole 
thing could just be a "personal" made-up TOCALL...

Just some thoughts... may not be relevant at all of course... will 
continue thinking (smellslike wood burning, eh!?
