Dave,
I believe that the "standard" require the wind to be measured at a 10 meter
elevation and the meter be surrounded by an open field. Your site would be OK.
Mine is not with all the surrounding trees.
There are several formulas how to "correct" a wind reading on other heights but
the knowledge I received (about 100 years ago) must have changed as I didn't
recognized it when i saw it last.

Two things to consider... usb has a limited range, past a certain distance you
need repeaters. I use a wired Davis station here and have no problem with rf,
though I did put ferrites on the power cord and the usb cable to control box
that is right next to the computer anyway. The other is that if you are
reporting to noaa (I don't know if wu goes to them or not, I report via aprs to
cwop which does go to noaa after filtering) they want anemometers at certain
heights so they get consistent readings across an area.
