Last month I gave a detailed presentation on  HF Propagation
during solar maximum to the members of the Madison DX Club.
Bill K2TNO recorded the presentation and made it available to
everyone here:

Its a lengthy presentation, for many viewers it will be best to view
it in short sessions rather than in a marathon session.

I can provide a pdf of the slides upon request
