[Elecraft] Monitor noise

[ZOOM]

Hi Paul;

Have you considered it may not be your monitor making all the noise!  The
power supply can also be a big source of noise.  I was getting S9 of noise
in my shack.  I too thought the monitor was the culprit but discovered it
was not the monitor but the power supply in my computer.  I bought a better
quality power supply and the noise is gone.  Yes monitors can be a source of
noise but also check the power supply in your computer.  A cheaply made
supply will generate allot of noise even though it's in the case.

Regards,
Robert
