Wayne, welcome to the shortwaves! I wrote an article for eHam a while back that might be of help to you. It is a tour of the HF bands. See it at:http://www.eham.net/articles/23337
There is also a printable version on my web site at http://www.n4kc.com
. Just click on the "Articles" tab and pick it (or anything else that interests you) from the list.
