I've decided to offer the various Space Weather software and the Space Weather Course at a SALE price, to make it easier for you to obtain these and at the same time, support HFRadio.org.
Your support - either by donation or by purchase, really helps out a lot. The cost of this site is carried primarily by me, out of my pocket. Sometimes, the budget is tight. When you help out, it really does HELP OUT! Everyone benefits.
