[Ham-Computers] Computer noise in receiver

Hi Jim:

The easiest way to solve your interference problem is to replace the CRT =
monitor with an LCD flat panel monitor.  LCD monitors do not cause =
interference like a CRT monitor. =20

You can also try changing the vertical sync rate and the display =
resolution.  This will not eliminate all interference, but it will =
change the frequency of the interference so that you may find a =
combination that you can live with.=20

Depending on the interference level, you may also reduce the =
interference by placing a couple of large ferrite chokes or torroids on =
the video cable at both the monitor and PC ends of the cable.
