Hi Peter thanks for that, I suspect they are not quite so much use in that
format. Do you still have the raw Spectrumlab data?? I think that will be
enormous but it is the only way to compare a day against solar activity
indexes. I am rather interested in daytime levels through the rising part of
the cycle but didnt get set up here....sheer lazyness :-))
You are a little closer to HGA22 than me so are getting more ground wave.
The ground wave here is much weaker than the daytime skywave. I did see some
interesting daytime variations around Sept 2009, when I did a 3 onth run
until we got a power failure. Also that PC was not a good time
keeper....probably because is was a slow one and SL was using a lot of
resources.
Best Wishes
