I am using an Orion to drive my Drake L-4B, and I operate mostly on 40 meters. My antenna is a 110 feet long dipole, center-fed with open-wire feed line, and elevated about 30 feet with the support f
John, I would try a ferrite bead on the wires of the GFCI. But, since you probably have more than one GFCI, that would imply if only one is faulting off, that it is overly sensitive to RF. I would ju
--Things to consider if you are going to use caps. First make sure the caps are UL rated for line voltage duty - VERY IMPORTANT! Second, depending on how you install the capacitors they may increase
John, I agree with Stuart on first replacing the unit and looking to choke the rf the wiring is picking up. Based on usual practice a GFI removed from service is usally disposed of. Many electricians
Many thanks for the helpful suggestions. I will start by replacing the breaker, and if the problem is not solved, I will try a common-mode ferrite choke. John, N9JG __________________________________

If you do add a capacitor, don't go to ground, go line to neutral. Too much C to ground will trip it from the line current not returned back through the neutral. RF trips of early GFCI were one of th
John; It sounds like your ground wire is a bit too long. I think MFJ makes a ground wire turner that might help reduce your problem. I had a 1 watt 2 meter rig that would trip off the GFCI from the o
John, If the suggested fixes don't work, it might pay to estimate the length of the wire running from the box to your GCFI breaker. There is a max recommended length on a span with one of these break
Hi, John-- I had a similar problem. One GFCI protecting the kitchen, garage, outdoor and bath outlets. Because the chain of outlets was so long, I figured it was putting enough of my signal into the
John, You might want to try a different brand of GFI breaker. In my experience, some are far more succeptible to RF interference than are others. 73 and good luck with it. Those problems are seldom f
Another thing to try, assuming your feedline is coax going out of the house, is to place a bead-style line choke some footage away from the house on the line. I have seen this reduce RF returning on
Hi, I had similar problems until I got a new GFI breaker. I understand the new ones are much less susceptible to RF. 73, Chas, W1CG _______________________________________________ TenTec mailing list
That seemed the easiest first step to do, so I ordered a new Square D 20 amp GFCI breaker on eBay. It arrived in a few days, and since I felt lucky, I replaced the breaker in the power panel without

Hi John, If you can make your antenna resonate on 40M (about 63') your problem might go away. Just make a temp one using coax and see what happens. I have a similar problem on 75M but it's due to the
Several postings had suggested that I replace my GFCI breaker. Since this seemed to be easy to do, I replaced the breaker and the problem seems to have disappeared. Thanks for your suggestion, but I
What happens without the L-4B? 73, Mike K9MI _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
