Some comments from Dan:
>Let me look at another aspect: Heard Island is

>Maybe one of the VE6's can relate their propagation on top band, but poor is

Right the point! The aurora ring goes away sometimes though. During those very
short periods I had a qso with Dan KL7Y over the north pole. And that was

Yes, but we dont have summer "nights". During the some dim hours of summer
"nights" we have only short and usually only fair to poor openings directly to
south. The Heard is not so close the pole so I think they have a bit more

And you might need the Gigawatt, but you can't hear the guys!

Good luck to us all & 73
