Hi Mark If you cannot locate the noise source, can you at least determine it's direction from you? A simple untuned loop should allow you to do that. An antenna noice canceller (ANC) works best if you can get a pickup antena as close as possible to the source, relative to the communication antenna, even if it is just to the edge of your property. I have both the ANC-4 and the MFJ-1026, and they both work well on a single noise source. They can't cope with multiple noise sources, though, or a single source spread out over an area, such a power line that is radiating along its length. Good luck and 73 Bob N6WG

Hi all, I have a S-9 noise level across the bands and despite some detective work, I have been unable to locate the source. I feel that I may have to resort to using a noise canceller in order to use the bands at the home QTH. Before I purchase one, I'm wondering if any of the subscribers to this list use one and if so, how effective are they? Apologies for the off-topic post but I though I'd canvass opinions before I buy one.
