This isn't an answer to your question, but a more straightforward way to accomplish what I think you are trying to do would be to make an array of two loops, where the azimuth of the individual loops can be chosen so that they null out the single point noise source that you are trying to null out with the NCC-1. The azimuth of the array can then be chosen to enhance in the direction of the signal you want to receive. IOW, the orientation of the loops is independent of the orientation of the array. The trouble with the SAL is that the null of the loops is always at a 90 degree angle to the angle of reception. You can't choose the angle. The other trouble with the SAL is that the spacing between the loops is always very small, and you can't choose that either. If you increase the spacing, it isn't a SAL any more, it's just ordinary loops in phase. Rick N6RK _________________ Topband Reflector Archives - http://www.contesting.com/_topband
