Hi Bob , I am sure that you are aware of this but do get the guys to
remember that it is not ground sunrise/sunset that matters. It is the
darkness edge about 1000kms away. You can heft a signal into the dark zone
ionosphere up to an hour before sunset and an hour after sunrise at this
part of the sunspot cycle. On good days trans-Atlantic signals have been
seen two hours after dawn in Eu.

I look forward to your tests and hope for a bit better luck with the
conditions. I have submitted a request to Ra for a quiet period but a little
geomag activity about 5 days earlier !!  :-))

It will be a pity if the wind farm QRTs you permanently from that site. It
has been a major landmark in LF development in amateur circles.

Best Wishes de Alan G3NYK
