[wxqc] CW7166 off the air (for now)

[Ken True]

I had spikes in wind on my Davis VP (cabled) until I'd put an 
opto-isolator on the DB-9 serial interface to the computer.  Probably 
had a ground-loop that really only showed up when it rained.  I used the 
B&B Electronics 9POP4 isolator
(

) and it cured the wind-spike problem.
