Thanks. I have actually studied your document Jim, and have recommended it to many others. :-)
I used what I had here. There are several bifilar turns through some of those big #43 beads. I even hung some #31 cores on the lamps themselves (which helped a little) and on the Romex feeding the fixture. That's all I have had time to do up to this point. I have some 2.4" #31 cores here I could use. But there's another problem that I want to fix: exactly how the RFI from that fixture is getting into my RX system. It's over S9 on my IC-765 on several 160m frequencies. But I just don't have the time lately. I didn't mean to hijack this thread. Anyway, time to go play in the contest now. 73, Mike www.w0btu.com On Sat, Mar 1, 2014 at 10:12 PM, Jim Brown <[email protected]>wrote: > > Big #43 beads on the ballast leads didn't fix it. >> > > Of course not.
