Good Evening,

    The week began with very hot weather.  It peaked on Tuesday at 110 
degrees.  Luckily no one started a fire.  I coped by eating jalapenos 
and drinking a lot of water.  Then it slacked off.  Two days later the 
clouds came back with morning fog.  It did get to 82 today but it felt 
very nice.

     The sun tossed a CME at us but almost missed.  Solar flux is up to 
95 sfu.  I was hoping it would go over 100 too.  The bands should be a 
little stronger with the normal summer noise.  I received three runs of 
coax this week.  Now to craft three more antennas.  The broken antennas 
are ready to become radials.  The main problem with those is all the 
slash lying around.  However, no one says radials have to be totally 
radial.  They just need to form a ground plane so a few zigs and zags to 
avoid large branches should be OK.  That being said it is my only option 
so it will work; it is simply a matter of how well.

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,

   There is a bird who enjoys singing from the top of one of the large 
hemlock trees in the backyard.  I have not been able to see him, only 
hear him.  I decided to record him which brought up the question of 
how.  Audacity is installed on three of my computers, two of them being 
laptops.  So I grabbed one of those and took it out back.  I captured 
twenty minutes of him calling while bees worked the thimble berry 
blossoms.  The built in microphones were fine, I did not need to use my 
separate mikes.  The tracks all had wind noise so I used the app's 
equalizer to mute it.  I could have used other tools to normalize the 
recording but only added a little compression.

   Now I can listen to my mystery bird as I search through the Cornell 
recordings.  The best I can guess so far is it is a warbler.  Its call 
had between five and sixteen phrases in it. Only the first four are 
stable, the rest are variations with the occasional mimic of neighboring 
birds.  If only I could sort sound files then I could write a search 
algorithm to match my bird.  A view of him in flight, or any sort of 
field sign would be nice too.  It may be a long quest.
