Good Evening,

    There was little noise on either band.  QSB was mild, except for 
those east of the Rockies on 40 meters.  There was a flutter on all of 
you.  Mostly it was reports of a chilly drizzle.  Wind too.  Cold wind.  
Snow is in my forecast, sometimes I look forward to it.

    I created some antenna radiation patterns as 3D objects last night.  
They are running on my 3D engine.  Its simple hidden face algorithm is 
very confused with the toroidal pattern of a loop antenna.  Sometimes 
the mistakes make the most interesting displays.  Once I tame them down 
I will add a UI to control a few of the parameters.  Height above ground 
changes the patterns, sometime drastically.  I had forgotten how much 
fun it was to write these models.  This morning I wrote a new Bessel 
function solver for the loop antenna.  Machines are much faster than 
when I first wrote this code.  I can step more finely for a smoother 
image.  I need to write a better hidden surface routine.

    Signals were loud today.  Solar flux was up but I'm not sure what 
happened to that solar breeze.  I did not hear it at all.


         73,
