In the last few weeks a new strong variable frequency 100% duty cycle RFI source suddenly appeared on 160 meters, radiated from a home one mile southeast of my QTH 24 hours per day. The RFI peaks in
During a visit to W2GPS this afternoon, we happened to discuss my 160 meter RFI problem. Rick remembered that he's seen nearly identical RFI on 160 meters at his QTH (30 miles from here) for several
Rick, Before you invest time searching for the RFI outside your home, you should be certain that its not originating from inside your own home. You don't have to introduce a new device for RFI to ori

Hi Tom, The receiver I use most frequently for RFI hunting is a Yaesu FT-847 that covers HF, 50 MHZ, 144 MHz and 440 MHz. It has excellent sensitivity and an analog meter. I use a short vertical on t
Phil, Our Baltimore area utility (BGE) has excellent RFI resolution capabilities and its never a problem to get them out here to resolve a problem. The Washington DC area utility (Pepco) is at least
Roger, You didn't mention how strong it is at your QTH. At a mile distance, it might be a high power source like a high efficiency furnace motor. Its time to get out a portable receiver to locate it.
Joe, I've had remarkably similar RFI for many years, but in my case its 18-30 MHz. The RFI sounds like white noise, but with one very important exception: it also has a much stronger strong narrow ba
Kurt, I haven't yet tried to correlate observations at the nursery to RFI at my QTH 1/2 mile away. This RFI has been present for many years, fortunately my antennas are directive enough to minimize t

Before we get too euphoric about the FCC's performance in this matter, this is the text of an email sent to me today by the ham directly affected by this RFI: "So this is the third letter, and a visi
Now this is a good reason to avoid use of MOVs in branch circuits! There are 700 reports of overheating and melting caused by Surge Protector Devices sold prior to 2003 and 55 property damage reports
Gary, This definitely is an off topic post, but its such a common and easily solved problem that its worthy of a reply. The Pyle PHE300 2-Channel Hum/Noise Destroyer is an inexpensive and extremely e
