I'd start with the filter that W6GJB and I worked out for use on 2000i generators, described on page 23 of k9yc.com/RFI-Ham.pdf It was added to the ARRL Handbook a year or two ago. Note that it's critical that all three conductors go through the choke, and they should NOT be twisted. 73, Jim K9YC _______________________________________________ RFI mailing list RFI@contesting.com http://lists.contesting.com/mailman/listinfo/rfi |
