Re: Wind Turbine Interference?



Well I copied signals that were back scattered from a farm windmill 
in Texas on 10.368 GHz SSB.  Distance was about 30-miles.  I believe 
that the power being used was about 1-5w.  I was portable on a 
100-foot high hill in the Texas countryside.  Direct path did not 
produce a strong signal.
