Default Propagation Getting Better Since Last Weekend

Thank you... and that's quite a photograph.

I dispute the generally-held opinion that higher sunspot numbers
mean "better propagation," though.

While the higher bands, say 7 MHz and above, improve -- the lower
frequencies tend to get shorter and absorption gets higher. This
bodes ill for 160 meters, for example, and 75 meters during the day
goes almost silent (though it may be better at night for short to
medium skip). And dramatic DX on longwave and mediumwave becomes
less frequent.

No matter what, though, it's interesting, and the clouds we cannot
see bring magic.


With my best,



Kevin, WB4AIO.
