[HCARC] Solar Noise Burst

[Kerry Sandstrom]

Harvey,

Unfortunately the radiation from the sun that creates the ionosphere 
that we need for long distance propagation also creates the ionosphere 
that absorbs radio waves and reduces signal strength. The late afternoon 
and evening are really pretty good as the absorption decreases a lot 
quicker than the MUF as the sun begins to set.  There were a few times 
when 17 m was pretty dead but the dead periods were separated by periods 
of pretty good conditions.  No matter what, these are probably the best 
conditions we've had in a while and we can only hope that it will 
continue into the fall.
