Good Evening,

    The forest is waking up.  Scents are changing.  A few hummingbirds 
reminded me to put up their feeder.  More woodpecker species are back.  
There is a variety of drumming calls.  Grouse will find good logs soon.  
I wondered if each woodpecker had a resonant frequency to transfer shock 
efficiently.  I found a lot of studies citing head trauma research.

   The sun tossed a CME at us, due between 0000z and 1200z on April 
24th.  So we may or may not be affected.  I expect occasional whistling 
sounds, followed by deep QSB, as the ionosphere feels the impact of the 
faster ions then the rest of the mass.


Please join us on (or near):

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
  7047 kHz at 0000z Monday (5 PM PDT Sunday)

    73,
       Kevin. KD5ONS
