No, actually they aren't. The NB function in PowerSDR is a noise blanker. The MFJ box is a noise canceler. > They both have one function - to minimize or eliminate noise. Sort of. Let me give you an analogy. Your question appears to me something like asking, "which is better, a dipole or a vertical antenna? They are both designed to transmit and receive radio waves so which one is better?" I think that you will agree that, because they work in a different manner that there will be occasions where a dipole will be superior to a vertical and vice-versa. Are you doing NVIS or DX? Is the signal vertically or horizontally polarized? Unless I have the parameters of your application, I can't give you a meaningful answer. So, I believe that it is not possible to answer your question in a simple A/B or yes/no fashion. They are different and will perform differently in different situations. If the noise problem you are trying to solve is multiple sources of impulse noise, e.g ignition noise, then the NB function will perform better. If the problem is a single CW noise source, e.g. noise from a bad power supply, the NB won't work at all and the MFJ unit will work better. > I don't care how they do it, or what is involved at this point such as extra > antennas, etc. Then it is not possible to answer your question as stated. > I am not talking about comparing how they accomplish what they are supposed > to do, I am talking about comparing the results of what they do. > > They both are supposed to blank noise, Which one does that best? Given the parameters you have set for answering the question, I cannot answer your question.
