There are a couple theories about the bad wind speeds.
One is that the wire from the remote thermo to the wind sensor must be secured and not allowed to move. If it does move, static electricity builds up and causes errors. That theory comes from La Crosse tech support.
Another is that the cheap telephone cord that La Crosse uses causes a problem.
Kenneth Lavrsen's WS2300 Wind Sensor Modification
The third possibility has to do with grounding issues. You should have the console and the computer plugged in to the same power outlet. La Crosse uses the DTR and RTS lines to create a "virtual ground" for the communications between the console and the computer. One of those lines is also tied to the ground plane on the console's printed circuit board. One of the wires that runs from the console to the
remote thermo and the wind sensor is also tied to the same place. This presents a problem if there is a grouding issue between the console and the PC. To test, try running the console on batteries for a day to see if the problem goes away.
Also, beware that because of this grounding scheme used wired mode, one of the lines on the serial port effectively runs all the way to the wind sensor. This can make your PC suseptible to lightning damage. An inline serial surge protector (about $20) is highly recommended if lightning is common in your area.

Since that time, I have started receiving several data errors during the day, mostly the same infamous ones others have received:

> I very rarely received these errors before moving the station and when I was using wireless. But now, I am getting them several times a day. Is there anything I can do to stop these errors from happening so frequently? Should I take the batteries out and restart the sensor, even though it is now hard-wired and plugged into the wall? I have tried resynching the console (holding down the + and - keys simultaneously until a beep is heard), but this did not fix the problem.
