I called Davis about this very problem.  If enough people call then maybe we 
can get it fixed.

> 1.  Support the 1 hour and 24 hour rainfall accumulation parameters in

> 4.  Support "rotatewx.aprs2.net" as primary APRS-IS server (this is an

> 6.  Standardization of temperature and humidity calculation:  2 minute
> sample duration to derive mean temperature and RH
