- Because of a sudden appearance of a line noise I had to get out my MFJ-1026 and set it up to cancel the RF intrusion while I wait for the power company to replace the defective street light in a subd

- Interesting results, Tod I have had exactly the opposite experience with my MFJ-1026. In fact, at my QTH I have found it to be absolutely, totally useless. Worse than useless, actually, in that in N

- easons on 160, always with the same conclusion. I've finally decided that it doesn't help in my situation because I seem to have bad line noise coming from nearly ALL directions, and, as I understand

- cancellers in series do directions... No. 1.) The MFJ noise canceller, while the best on the market **at this moment of time**, is a marginal design for IM dynamic range and noise figure. I wouldn't

- I've been trying the MFJ-1026 again today during daytime while the band is devoid of signals and QRN propagated by the ionosphere. I wanted to concentrate only on my specific local noise source(s). G

- For a noise canceling unit to work, the noise antenna has to: 1) pick up the same noise that your main antenna is picking up that you are trying to cancel and 2) the power ratio and phase relation of

- 2.) The sense antennas would have to be close to each noise source if the noise arrived from different directional angles. Each sense antenna would be required to NOT hear any noise from other noise
