[Fourlanders] solar hash

[Ron Rogers]

Yes, this is beginning to be a real problem.  Every time I drive up RT 321
in NC going to Jim's QTH I drive right by one of Apple's 100 acre
multi-megawatt solar farms that powers it's nearby Data Center near Maiden,
NC. When I begin to get close to the farm and I am listening to my HF rig in
the Suburban the noise floor quickly ramps up to a solid "raspy buzz" for a
couple of miles.

 

The issue is the commercial DC to AC switcher type power inverters being
utilized that currently don't have to pass the same FCC emissions as
consumer devices. And when you are talking about megawatts of power
conversion taking place the entire system literally screams !  Until enough
people complain about it nothing is going to be done.

 

BTW: there is a GREAT front cover article in the April QST about Amateur
radio and the challenge of solar power

At a conference that I attend annually, they had a session on solar
generation.  In Georgia, if you draw a line from Columbus to Augusta, almost
all of the installations are south of that line.

 

Of interest was a video/audio track.  It was recorded at a substation that
was one (1) mile from the solar facility.  The 60 Hz. hash on the AM radio
band was bad.  It was from the solar facility!

 

Some facilities can produce hash higher than the AM radio band.

 

F.Y.I.
