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

Wed, 19 Jun 2002 22:13:19 -0500

Try to isolate wther the noise is the computer or it's monitor. If its the
monitor you might try increasing the shielding. There was a post early on in
this group and he had his shielded the monitor using a conductive paint that
was a GE product. The computer box can be moved using extension cables and
maybe addtional shielding there too. Mouser has braided sheild copper
"tubing" to pass cables through if nessasary also. Jon AB9AH
