[Boatanchors] Band Conditions

[Bill Cromwell]

Hi Ray,

That 11 year cycle affects all the bands one way or other even if it 
doesn't shut all of them down. There are other cycle period associated 
with the sun too. 21 and/or 27 years rings a bell. That is in additional 
to other , seemingly random events of varying duration. Like you, I am 
not selling my radios yet.

73,

Bill  KU8H

Sit tight and wait until this fall and winter before making a judgment about the apparent destruction of the conditions and whether its permanent or not.  In my experience, it's nothing out of the ordinary, though I agree it is frustrating at times.  But, variable conditions are part of the intrigue of ham radio.  Things can change in an instant from good to bad, and bad to good, sometimes lasting for a while, sometimes only minutes.
