Tom,

This is a statistical summary of your weather station's reports which is 
a service provided by this listserver.  The summary shows exactly what 
you already know, your data tracks well with the professional weather 
stations.  Of the 88 reports evaluated, not "questionable" observations 
were found for your pressure (ALT), temperature (POT TEMP), wind 
direction (DD), and wind speed (FF).  A small number of dew point (DEW 
PNT) reports, 3 of 88, were flagged.  This doesn't mean the 3 dew point 
reports were wrong, just that they were different from what was expected. 

The warning message at the bottom of the message was generated because 
your weather station's location in the CWOP database is different from 
the location you are reporting in your current APRS reports. 

1. CWOP database location:
http://www.wxqa.com/states/NC.html
Latitude:         36.48583N  
Longitude:      76.07533W

2. Position currently in your APRS weather reports:
http://www.findu.com/cgi-bin/find.cgi?call=CW2967
http://www.topozone.com/map.asp?lat=36.45417&lon=-76.08083&s=100&size=s
Latitude:        36.45417N
Longitude:     76.08083W

I recall we had determined the position in the APRS message is the most 
accurate position, but this position apparently didn't get updated in 
the CWOP database.  If this is true, Julie and Russ will update your 
CWOP station data with the #2 position listed above.

Regards,

Dave
CW0351
