I would like to use my computer for logging as I work DX stations, would
like to try PSK31, etc. BUT.... the computer wipes out half the HF bands. I
waited until the hard drive went into sleep mode and the RFI was much
better. I tried grounding the computer case to an earth ground but to no
avail. Anyone else have this problem and how did you remedy it. My box is
not super fast, being a mere Intel PIII 450 mhz proc. It has the usual
things, vid card, external modem, and sound card. Your help appreciated.

The monitor, even LCD, is a significant source of RF noise.

Also worth checking the cabling, and upgrading to shielded cable if
you don't have now.

Use one source of grounding for the system.

Happy trails,
