I only allow Antec PC Power Supplies in this house, as they seem to have excellent EMI/RFI suppression. 73, Mike W5CUL -----Original Message----- From: flexradio-boun...@flex-radio.biz [mailto:flexradio-boun...@flex-radio.biz] On Behalf Of w8...@yahoo.com Sent: Tuesday, December 30, 2008 12:09 PM To: flexradio@flex-radio.biz Subject: [Flexradio] New Computer= noise Help please! Santa brought me the pieces parts for a new computer and I have successfully assembled it, Flex 5000A runs great on it at 10 to 15% CPU useage @192 range But: horrific noise peaks at 100 khz intervals, This is most pronounced on the 80 meter band. There are minor peaks at 50 khz intervals. The overall noise floor is also higher. Pieces Parts as follows: Case&Pwr Supply--Compucase 6AR6BS2fxFX585 Motherboard -------Gigabyte GA-EP45-UD3P P45 775R Video Board --------Gigabyte N95TOC1GH 9500GT R CPU-----------------Intel E 8400 3G 775 45N R Memory------------- 2Gx2/CORS Harddrive------------WD 2500AAKS DVD-----------------Samsung/SH223 Have tried turning the monitor off. The only thing that helps the noise is to turn the computer completely off. Removing the antenna from 5000A seems to eliminate it on the panadapter as well as audibly. When I turn the 5K off the noise is still present on a separate rig. Any suggestions would be appreciated. 73, Art K8JK _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/
