[RFI] Re: Topband: Local noise environment (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Mon, 16 Feb 2004 20:29:33 -0500; Hissy noises slightly modulated by 120Hz or multiples generally come from real high voltage power lines (Three phases can make 360Hz buzz). You get two noise peaks per AC cycle. That's because the ar; /archives//html/Topband/2004-02/msg00261.html (8,199 bytes)

In principle I would think that a capacitor wouldn't generate any extra noise unless there was some arcing going on in; /archives//html/Topband/2004-02/msg00265.html (8,688 bytes)
