We did not expect to see raw WX formats on the air.  At the time
of the APRS spec, there were 4 different formats from Peet Bros,
and 3 different instruments from Davis, and new ones were being
introduced every year.  It was impossible to see the future and
see what would be the dominant formats.  The APRS spec only had
one, and it was assumed that any remote APRS WX station would
have a processor to convert to the on-air APRS format.

Now Opentrack and Byonics and others have stations that can do
the conversions.

Also the TM-D710 does decode the Peet Packet mode on the air...
I think...
