Topband: 160m & 80m RFI issues requesting ideas for ANC4 sense antenna to cancell out local noise
HI Guys, I have an intermittent RFI issue that comes from a subdivision about a 1/4 mile away. To combat the noise I have been trying to use my ANC4 and I built a sense antenna out of an 80m hamstick that I put 20 feet in the air yesterday for a trial to cancel the noise on 80m (cheap and easy experiment). The location of the sense antenna is at the corner of my lot as close to the subdivision that I can get. The design is the hamstick as a vertical element and two 102 inch whips as elevated radials. The noise is s9 on my 1/4 wave 80m vertical and 160m inverted L. This is a multi band vertical with wires for 40m, 80m & 160m. I also have other antennas such as a 160m 2wl long loop and a trapped dipole. What is interesting is that the noise is significantly less on the loop and the dipole. I attribute this to the noise being vertically polarized based on my research on the internet. Also this sense antenna is roughly 150ft away from the vertical antenna. The issue is the level of the sense antenna noise is significantly less than the vertical and I am not able to find a null point that makes a difference. I can however use the loop antenna and I have enough signal with the hamstick experiment to get a null as the received level of noise on the loop is significantly less. So I believe I need more receive gain on the sense antenna. So with the above in mind, is there a low cost pre-amp that I could use on the sense antenna to boost the signal? Or what other ideas are there for a sense antenna. I don’t want to put up another 1/4 wave antenna for sensing. I have read where folks suggest putting 50 ft leg dipole at 5 ft above the ground for 80m & 40m but I think the noise is vertically polarized and this wont do much but I could be wrong and have been wrong before. I have room to try stuff on the property for antenna ideas so that’s not an issue. However, I need the sense signal level close to the interference level or I have no chance to get a cancellation of the noise. Again any and all ideas is greatly appreciated. ~73 Don KD8NNU 2014 3905CC Top Gun :-) -.- -.. ---.. -. -. ..- _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: 160m & 80m RFI issues requesting ideas for ANC4 sense antenna to cancell out local noise
HI Rick I have tried this idea also but again not enough gain on those antennas. The vertical has s9 noise the others are 1/2 that level same as the sense antenna I just built. That is why I think I am able to null the loop easily but not the vertical using the hamstick sense antenna. For what its worth, I never was able to null the signal on any of my antennas until I did the trial hamstick yesterday. It was my last attempt and now that I can null the loop I know its possible but it’s the equal signal problem.

Re: Topband: Boradband noise on 160 meters tracked down toapartmentcomplex
Hi Tom Thanks for your comments in the email below. I have a 80m noise that is from a local house source and your comments below have me thinking about how to implement a vertical noise sense antenna. I believe the noise to be vertically polarized as my horizontal loop does not have the same noise receive issue as my 80m vertical does. Thus my plan was to set up a vertical antenna outside and connect it to my ANC-4 noise nulling system as the sense antenna. I currently used the ANC-4 with a wire strung in the basement with the target to null out plasma tv noise and this was reasonably successful until the new noise showed up. My current sense system does not hear the noise at all so something else needs to be set up. The vertical element I was going to use was a simple 102 inch whip, however based on your comment I am thinking a longer vertical element would be better but I am not sure how to pick a vertical length. I have concluded based on driving around this weekend with a simple direction loop that it is less than 1/2 mile away from me and its comes from a house. It was active this Sunday morning and using the simple loop I am confident that it is from a specific house. It is not power pole noise that is something that I recognize easily with my mobile operations. So specifically noise is 80m and I want to null it so I can use 80m again. My thought is a vertical sense antenna, my first thought was a 102 inch whip but I can make something longer. I know the direction of the noise so I can put the sense antenna where needed so I am open for suggestions. This was the noise that showed up and then disappeared and now has returned intermittently so I need to attempt to try and null it out.

There are a lot of popular misconceptions about this. The noise does always not have to be a different direction, or even just one source. The MFJ nuller and other similar systems will remove noise when: 1.) The sense antenna is much closer to the noise, or picks up the noise much better compared to signals than the listening antenna does. This is true no matter what the desired signal direction. In this case you are eliminating a source by having a sense antenna hear the noise much stronger than the sense antenna hears desired signals. 2.) The noise is one or multiple sources from the same direction and the sense antenna is reasonably close to the RX antenna and the correct direction from the RX antenna. The noise has to be a significantly different direction than the RX direction. You are just eliminating the general noise direction in this case. 3.) The noise can be from multiple sources radiating from the same point. A long power line with multiple insulators arcing that is passing by close, and conducting emissions to that point, might be an example. You are nulling the point of coupling, rather than the noise generator's location. _ Topband Reflector Archives - http://www.contesting.com/_topband _ Topband Reflector Archives - http://www.contesting.com/_topband
Re: Topband: New RF interference killing RX at my QTH
Well I made some progress tonight on the way home. I used my mobile rig with hamsticks to listen while driving on the way home from work. I tuned to 3.902 which is a very strong frequency that gets trashed at the home QTH and used a 40m hamstick as the receiving antenna. The idea for this setup was to be able to attenuate the signal as I got closer to it. Anyway while driving home with the pre-amp on the IC-7000 when suddenly the noise was present and strong less than 1 mile from my house.I drove around until it got real loud and turned the pre-amp off and it went away. I then drove around with the pre-amp on until it was at about an s7 on the meter then turned the preamp off as I was close and then drove around until there was about 1 s-unit showing on the meter. I could hear the noise with the pre-amp off when close and the s meter small reading confirmed that I was real close. The noise is clearly in one subdivision close to my house but I can not tell what is the source at this time. I also know the noise does not show up on the AM radio in the car although bad power poles do show up. So to me major progress has been made, now I need to identify where in the subdivision or maybe what house this trash is coming from. Next short term step is to listen to the links several folks have sent to me to see if any of them match what I am hearing so I know what I am looking for. I will keep the list updated as I learn more about the problem. Cheers and thanks for the tips so far.
