The weather vane on the voice wind talker is stuck. Just because it's stuck at WSW doesn't mean it's flyable .
Steve R is going up to lubricate it in the next few days. In the meanwhile:
1) The wind speed for the voice wind talker is accurate.
2) The wind speed and direction on the web (http://flyfunston.org/newwebcam/ ) is accurate.
3) Just to triple-check, have a look at the windsock in that webcam to see what it's doing.
