Hmmm, that problem sounds like one I had dealt with before.  Will look into

BTW, checked your weather station data and your getting rained on big-time!

When you are looking at the code I wish you would take a peek at the
barometer routines.  My barometer looks good displayed on the LCD in inches
of mercury.  I could never get it to display millibars correctly.  The main
problem seems to be the TNC transmission, probably the conversion to
millibars to meet the APRS spec.  It only reports whole millibars most of
the time and not tenths of millibars as the pressure changes slowly.  On
occasion there will be a .1 or .9 creep in but mostly whole numbers.  This
is seen as significant stair stepping when viewed on WinAPRS where each five
minute transmission is plotted.  The station is n5kuk (AR301).
