Solar Data and HF Propagation Tools have Moved!

Sorry all, but it was to hard to maintain in two places, and this page was geting to big. Either click on the image to the left, or on this link http://www.hamqsl.com/solar.html to go to my Solar and HF Propagation Website. It still has all the tools, conversions, and a lot more. If you are interested only in the solar and HF propagation data, then you can bookmark that page.
