Bob D. Schrieffer:
I'm looking for a guide to "what bands are open when, and how far". I'd like
to set up a schedule with a couple friends but I don't have a good feel for
'what band / what time'. Does anyone know of a good 'rule of thumb'
reference that doesn't get deep in propagation theory?


It's very complex to make a good prediction.
Seek for propagation software, like AREPS, ITS HF, etc. that's would a
little help.
