    Just curious if anyone is using one of these for APRS and a TNC such as the KPC-3. Since I can't find my box of thermistors, I ran across this device on the net and everything this far shows it connected to an Arduino and running a prgm to decode the strings of data.

    Doug, temperature, pressure, and humidity are encoded in the weather report packet.

    I got this description from this old document http://www.aprs.net/vm/DOS/PROTOCOL.HTM


    WEATHER REPORT: APRS uses the underline symbol character for WX reports.
    For these, the COURSE/SPEED field is used for the WIND and the remainder
    of the comment line contains other weather items. See WX.HTM

    r is in hundredths of an inch of rain in the LAST HOUR
    p is in hundredths of an inch of rain in the LAST 24 HOURS
    s is INCHES of snow in the last 24 hours
    b is in tenths of millibars
    h is percent humidity (00=100%)
    dU2k is Ultimeter 2000, /U5 is the 500 and /Dvs is Davis
    The "d" means it is running DOS


    Have fun
