it happens maybe once a
decade. You simply have to be there when it happens.

True grey line radio wave propagation rarely occurs on 160 meters and true
long path propagation even less. When it does the opening is usually only a
few minutes long. Instead it's usually a skewed path that includes RF signal
ducting in the E Valley/F layer propagation region.

Hi,
I sometimes look at the forecasts and space weather info but that is
more often "after action" done in the chair. If we look at that first it
gives a place to start. But I agree the final result comes from the
chair time.

Kris N5KM asked about greyline propagation predictions. Since his question
was posted to the topband reflector, I assume he's only asking in relation
to 160-Meters.
We do not have any reliable propagation predictions for greyline on 160m.
In fact, we really don't have any reliable propagation
VOACAP and other propagation forecast tools provide shortpath and longpath
predictions.
However, at my sunrise I'd like to know the greyline path prediction. For
instance, SouthWest
to Asia (from Texas). Does anyone know of a propagation tool that shows
greyline predictions?
Thanks,
Kris N5KM
