I think the best advice regarding all these propagation programs is not to
place too much reliance on them. There is no substitute for turning the
radio on and seeing what you can hear. I have often had to say to people who
use VOAProp or HFProp that they do not predict propagation. All these
programs will do is help you to see how propagation changes with the time of
day, season of the year and solar cycle, and help you gain an understanding
that would otherwise take years of experience to achieve. But they only show
average conditions, not actual predictions. Real propagation changes a great
deal that is not reflected in a smoothed sunspot number or a solar flux
reading at one point on the globe.
A couple of days ago on the afternoon west coast Stateside stations were
loud and clear here in Europe. Yet there was nothing remarkable in the WWV
bulletin to lead anyone to expect that. If I hadn't turned on the K3, I
wouldn't have known.
