1. [RFI] Help with broadcast interference (score: 1): Author: "William Liporace - NA2NA" <na2na@earthlink.net>; Date: Thu, 12 Feb 2004 22:01:56 -0500; Hi Folks, Here is my problem. I was sent here for ideas. I have three loud broadcast stations with in close proximity. The weakest is 810 and the strongest is 1540. The problem is that 1540 is the al; /archives//html/RFI/2004-02/msg00068.html (8,020 bytes)

Have you considered adding stubs to the tower -- you can shorten them with tuning caps -- to choke off current flow along it?

Re: [RFI] Help with broadcast interference (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Fri, 13 Feb 2004 05:04:30 -0500; broadcast Hi Will, It is VERY unlikely common mode chokes, especially just adding a few beads on the coax or some wires, will do anything at all. First the impedance of any beads is generally far to; /archives//html/RFI/2004-02/msg00071.html (9,346 bytes)
4. Re: [RFI] Help with broadcast interference (score: 1): Author: Roger Parsons <ve3zi@yahoo.com>; Date: Fri, 13 Feb 2004 14:47:15 +0000 (GMT); I would agree with Tom. You need to ensure that the level of interference at the receiver input is reduced to a level with which the receiver can cope. uV/m measurements are very interesting, but onl; /archives//html/RFI/2004-02/msg00077.html (9,166 bytes)
5. Re: [RFI] Help with broadcast interference (score: 1): Author: "Jim Brown" <jimbrown.enteract@rcn.com>; Date: Fri, 13 Feb 2004 00:34:52 -0600; Yes, these are some pretty high field strengths. Are you sure they are correctly measured? I suspect they are not. Perhaps your antenna is influencing the measurement. Exactly how far are you from th; /archives//html/RFI/2004-02/msg00078.html (9,617 bytes)

7. Re: [RFI] Help with broadcast interference (score: 1): Author: "Tom Rauch" <w8ji@contesting.com>; Date: Mon, 16 Feb 2004 05:52:41 -0500; Right here is the key: You can do that. Anything the meter reads is USELESS because the tower becomes the antenna, not the loop in the FSM. It, in effect, makes the FSM have a pretty large reasonably; /archives//html/RFI/2004-02/msg00099.html (8,673 bytes)
