1. [RFI] High local noise level... (score: 1): Author: "Kenneth G. Gordon" <kgordon2006@frontier.com>; Date: Sat, 14 Mar 2015 18:20:00 -0500; Today, I connected the audio output of my transceiver, a Yaesu FT-890, set to AM-wide, tuned to 3580 KHz, into my computer and fired up Spectran. Spectran is exhibiting a very wide-band series of pea; /archives//html/RFI/2015-03/msg00008.html (7,645 bytes)
2. Re: [RFI] High local noise level... (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Sat, 14 Mar 2015 16:41:57 -0700; Spectran is exhibiting a very wide-band series of peaks in the noise which appear to be multiples of 60 Hz. You are seeing harmonics of the AC power line. This is an indication of improper bonding of; /archives//html/RFI/2015-03/msg00009.html (7,773 bytes)

(score: 1): Author: Mike Martin <mike@rfiservices.com>; Date: Sat, 14 Mar 2015 23:08:02 -0400; If you haven't made changes in your shack its unlikely the cause is bonding on your equipment. However it is likely to have a rectified power line noise accuring on only the positive half cycle. Can; /archives//html/RFI/2015-03/msg00011.html (8,411 bytes)

A fundamental cause of triplen harmonics of the power line (divisible by 3) is leakage current from the power line causing a voltage drop on the "green wire where that equ; /archives//html/RFI/2015-03/msg00012.html (9,195 bytes)
