Topband: Summer in the Northern Hemisphere

Thank you all for the interesting perspectives of why this is. I 
never thought about one hemisphere having more QRN than the other 
though I always think of rain forests in S. America and them having 
massive storms in their summer. 

160 really is our challenge, I remember being stunned how loud S. 
Georgia was coming in on 30M, easily 599 on my K3 S meter. 160M, 
hardly moved the meter but I could hear them easily.

Thanks for the different links, I had one lightning link saved in 
Chrome but it was eventually a dead link and I never looked farther. 
Now I have two links saved. I'll keep them next to the WA7BNM Contest 
calendar.

Thank you again for all the thoughts and links.

73,
