[Elecraft] Elecraft CW Net Report

[kevinr]

Good Evening,

    Both bands were stronger than they were two weeks ago.  Less QSB on 
twenty while on forty meters had less on those farther west with a fast 
flutter on those to the east.  The sun angle seems about right for 
longer distance work on forty.  By the end of the second net it was dark 
here.

    Topics ranged from tuning vertical antennas to humans being launched 
into space, Boise real estate to Midwestern snow storms. Low noise 
helped me dig a little deeper to work PA and VA.  It has been a while.

K2HYD - Ray - VA

KB3FBR - Joe - PA

K0DTJ - Brian - CA

W8OV - Dave - TX


    I am working on some code to visualize antenna radiation patterns as 
animated 3D surfaces.  This is an extension of work I did for my grad 
school thesis.  There are many variables I could modify as user 
controlled parameters; I need to pick those which effect the system the 
most or are the most important to amateur use, while setting the others 
as fixed.  These patterns are created from equations straight out of a 
text book so you can track how each variable is introduced into the 
theory.  I need to tune my dynamic-circular queue for steady state 
performance.  The display loop needs to get fed enough frames, quickly 
enough, or have a governor added to it.

    Until next week have fun and get on the air more, the bands are healthy,

       Kevin.  KD5ONS
