George, I don't have the '04 handbook, but I believe the HPF shown in the '02 is the same. At my last QTH I was less than two miles from a 10KWday/1KW night AM station on 1720. The filter which I built and used successfully for keeping them out on 160 was the nine section one shown in October, 1983 QST, starting on p17 by John Webb. It has a much sharper cutoff than the one in the '02 Handbook. 73 Don K5AQ 7 _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
