I have one and also have a small horizontal receiving loop around the perimeter of the property with the intended purpose of picking noise generated by the neighbors' stuff. The MJF unit works if you can adequately pick up the noise through the receive antenna. I made a video of it that I put on youtube, but the video actually turned out pretty poorly because you just can't hear the noise I was demonstrating eliminating in the video. Oh well. When I originally put this in, I was using it to eliminate both a rogue plasma tv and also the neighbor's pool pump. Both of the offending devices have since been replaced so I don't use the MFJ 1026 as much, but it's definitely a nice tool to have in the box.
I have kicked around the idea of putting up an active receive antenna for it but am concerned that I won't be able to place that antenna far enough away from my regular HF antenna with legal limit usage. I've always thought that this type of functionality could be built into the K3/K4 since it already has a separate RX input. Maybe Elecraft would consider it in a future OS upgrade feature for the K4?
