CW2274,
There is one particular Davis owner up in Greenville near where I live that sends to CWOP, and the pictures this person uploaded show the station on the roof. The thermometer is out of range in the summer. It makes others look off. Also to my east near Atlantic Beach, they have stations that are way off. When you try to compare your data to that mess, it is not helping anyone... At least get your thermometer right, if nothing else!
