1. [RFI] Noise cancellers.... (score: 1): Author: "Kenneth G. Gordon" <kgordon2006@frontier.com>; Date: Fri, 21 Mar 2014 20:18:40 -0700; Oh. BTW, Mike WU2D makes it pretty clear that in order for the noise cancellers to work properly, they really need a "noise antenna" that is identical with your transmitting antenna. Kenneth G. Gordo; /archives//html/RFI/2014-03/msg00110.html (7,260 bytes)

(score: 1): Author: W0MU Mike Fatchett <w0mu@w0mu.com>; Date: Fri, 21 Mar 2014 21:40:11 -0600; I know a local who has tried the MFJ and ANC and says the MFJ actually works better. Believe it or not. I have used the anc4 with a receive antenna and it did a reasonable job. Mike W0MU Kenneth G. G; /archives//html/RFI/2014-03/msg00111.html (7,258 bytes)

(score: 1): Author: Pete Ferrand <petef@sprynet.com>; Date: Fri, 21 Mar 2014 23:38:03 -0500 (GMT-05:00); I have also had both the ANC and the MFJ and kept the MFJ, better in all respects. From what I understand the DX Engineering NCC-1 is way better but at $600 it should be. I found the main thing with; /archives//html/RFI/2014-03/msg00112.html (8,763 bytes)

I use a 24ft vertical fed with ladder line working against a 100ft of chain link fence, with it's own tuner as the noise antenna.

(score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Fri, 21 Mar 2014 23:20:46 -0700; If patched inline with the TX output, the ANC-4 is a nasty key-click generator. No problem if it's in an RX antenna patch point. I have no experience with the MFJ. Note that ANY noise canceller can o; /archives//html/RFI/2014-03/msg00114.html (7,700 bytes)
6. Re: [RFI] Noise cancellers.... (score: 1): Author: Jerome Schatten <romers@shaw.ca>; Date: Sat, 22 Mar 2014 09:06:24 -0700; @Jim Brown.. What you say is of course true -- you can only kill one at a time. That said, you can often times choose your target, by adjusting the phasing. Getting rid of the most offensive noise so; /archives//html/RFI/2014-03/msg00121.html (9,173 bytes)

These units have the ability to null out plasma noise as well as being non-res; /archives//html/RFI/2014-03/msg00122.html (10,060 bytes)

Do you use it in conjunction as a noise antenna for a noise canceler or alone? What if the signal you are trying to hear is in the null zone?
