Hi All, These last discussions about man made noise in city areas let me wonder about all those noise-cancelling devices (noise capture by a second "noise" antenna and summed in opposite phase to desired signal coming from main rx antenna to null noise out) Are they useful or only expensive toys ?? Thanks Federico _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
