TelescopeMan does a 2nd video (better resolution) on free ham radio software. If you wonder what hams are using this video will answer many of your questions. See the comments for links to the software shown in this video. LOOK way down at the bottom of the comments.
My presentation at the radio club was 1 hour and 15 minutes– I was able to CUT IT DOWN to 40 minutes in this video— it goes fast so get your pen and paper out NOW!
