Re: LF: Best results so far from Germany to Tasmania

Hi Jay yes thanks, and that it perks up a bit with a low level coronal hole event around Kp=4. I have just found a useful source of reading matter so I have invested this month's beer money :-))  Hopefully I will have a more "scientific" explanation when I have absorbed that. Even is suffering from too much blood in my alcohol stream by then.

Interesting explanation - always appreciate your thoughts on the subject! Have certainly witnessed the 'quiet condition signal drop off' for years on the T/A path.
