Topband: greyline prop forecast

[Bill Cromwell]

Hi Carl,

It would be nice to have some hard numbers but they are subject 
sometimes to misinterpretation. I would have liked to see some hard data 
about this too and not just for 160 meters. It seems like that grey line 
involves some sort of magic but just when we think we have it figured 
out we get fooled - again. The most reliable 'forecast' isn't really a 
forecast at all. As you have said - just turn the radio on and see 
what's available. I am afraid too many of us look at the forecasts and 
decide there is nothing to hear and so the radio sits cold and dark. How 
many opportunities are missed that way is anybody's guess. There are no 
hard numbers for that either.

73,
