I have not heard of long distance solar array QRM on the HF bands. I have a few moderate sized ones with a mile or 2 from me and I hear nothing from them (very low noise QTH). Very close in (less than 1 - 2000ft) might be a very different story.
I would be interested to hear of other topbanders observations. Ed N1UR _________________ Topband Reflector Archives - http://www.contesting.com/_topband
