Good Evening,

    Cool rain changed to warm rain, then torrential rain.  The trees are 
green, as is the moss.  The ferns are either golden, bronze, or faded 
brown.  The mushrooms are getting eaten by a variety of rodents.  The 
wind has caused the fir trees to shed skeins of lichen which the deer 
prefer.  I have not seen any elk this week but I have seen many 
hunters.  I sense an inverse correlation.

    The sun has calmed down.  The spate of CMEs has slacked off to 
none.  I expect 20 meters to have less QSB with a some noise. Forty 
meters should be OK at first with steadily increasing flutter.  I will 
start listening on forty meters early.  This is a test of conditions 
right before sunset.  Over the next two months we may need to move to 0000z.

Please join us on (or near):

14050 kHz at 2300z Sunday  (3 PM PST Sunday)
   7047 kHz at 0030z Monday  (4:30 PM PST Sunday)

    73,
       Kevin. KD5ONS

// create a sample array

// build a linked list of samples from the array
// add .x, and .dx values here
// inject .current and .pen values at feed point
// walk them to far end of the antenna
// bounce back to feed point
// tune the wire length to the wavelength to demonstrate resonance
// move feed point: center, end, off center, 1/4 wave
