[R-390] Ham Shack Grounding Help!!!!

[Kurt]

Kim
A simply thing to check is the shield connections on your antenna coax
fittings. When the shields work loose on the bnc's that I use I get serious
computer noise. Tightening up the connection solves the problem every time.
There are two computers plus a network hub and cable modem all in the radio
room and in general I have very little noise. The switching power supply for
the monitor is the worst and the "wake on LAN" signal from the mother board
has some discrete frequency interference. It is possible for radios and
computers to peacefully coexist.
Good Luck,
Kurt Holbrook
