[Elecraft] TV interference

Fri Jan 24 07:32:01 2003

I solved my (very serious) Computer monitor TVI situation by just
experimenting with different "refresh" frequencies inside the properties of
my video adapter.   It works!  (Currently my best results are at 85 Hertz).

One reason I use a laptop in the shack is lower, or in my case no hash or
trash from the monitor.  My other machine using a CRT made most of my
receivers useless on many bands.  Alot of TV's, VCR's and appliances cause
reverse
"TVI".  Actually it's all a consiracy against me, because I used to cause
such TVI years ago with my homebrew six meter rig.
