Having spent a fair bit of time w/ Davis yesterday getting them to 
update their windows s/w for APRS-WX/CWOP... if I can find Peet at the 
American Meteorological Society meeting, I've some requests for them, 
too! And you just raised a key one.  We should have a standard value for 
*Missing Data* such as, -99999 (which is, in fact, one such well 
recognized value in the meteorological community).

Nor do a lot of other consumer-grade, or APRS-WX, programs.  It's more 
an oversight, I think, than a mistake.  However, thanks for pointing it out.
