Several years ago I bought a amplifier and decided very early one morning to see what it could put out on 40 Meters. The antenna was a dipole over the top of the house. Well, before I was finished tu

The list should mostly be about Amateur RFI, however, I don't mind non-amateur discussions once in a while. Mike AD6AA _______________________________________________ RFI mailing list RFI@contesting.

I had the same problem. I went out to see what I had done. It was years ago. On the wire going to the button to open and shut the door, I re-wired it with a shielded cable and grounded it at one end

About the same here. Most are not lasting a long time and I have not notice more RFI. Maybe my noise level is hiding it. I haven't noticed a change in my electric bill. Mike AD6AA MikeR <nf4l@nf4l.co

Don't give up. "Away" is relative, any separation is better than none, 4 inches of separation is a lot more than twice as good as 2 inches. Don't run cables and coax parallel to any automotive wiring

I wonder if GMC and Chevy have different bonding and grounding requirements? On most bands, I have less than a S unit of noise. (2004 GMC Pickup) Mike AD6AA __________________________________________

Good thing to try. Unless it's the DVD that's the problem. We don't have TVs anymore, it's entertainment systems and any one of the things hooked up to the TV can cause the problem. Unplug everything

Get a different RF ground for your antenna. The random wire is 1/2 of your antenna, the other half is the AC ground wire of your house. I would be surprised if the lamp is your only RFI problem. Your
