Here is followup & resolution regarding the RFI we tracked down about 3.5 weeks ago at the QTH of N9CJT that we suspected was DSL/VDSL as we had identified the RFI was coming from a box and associate
Hi Pete, Looking at the RF spectrum that signal occupied a total of 20 KHz (10.135 to 10.155 MHz) with lines every 50 Hz within. It did indeed look like the typical OTH radar signal to me and a quick
Hi Jim, You said "The neutral is NOT run to a 240V outlet, only the two phase (hot) conductors and green" and I think there needs to be a little clarification, especially for those that might be deal
I had a very interesting case involving RFI on 160 and 80 meters and actually a little bit on 40 meters at my QTH which I was able to resolve yesterday. For those interested here is a link to a youtu
Hi Mike, I was trying not to comment because I'm not sure this topic (thread) is RFI related. Nevertheless I did read the document you provided a link to and I did a text search on that document and
Just noticed around 3pm EST a strong (S9) constant carrier on 7.025 MHz that appears to be skywave. A very crude quick check with portable flag indicates its heading is approximately 130 degrees from
Hi Dave, I just looked at that signal using an SDR receiver set to an RBW of 9.2 Hz and I dont see much but possibly 120 Hz sidebands but they are at least 50 dB down from the main carrier. Don wd8ds
Hi Dave, I just turned automatic frequency control on my SDR receiver to track the change and have not observed a movement of more than 3 Hz in over a couple minutes time but some of that could be on

Hi Mark, Great advice from others on here and I was not going to respond to your post but I finally broke down, so here goes. About 10 years ago I experienced RFI from a VFD (variable frequency drive
This past Friday I tracked down some RFI that has plagued Justin (N9TTK) for a long time. The RFI was the typical every 1 second (approximately) tick tick tick sound of an electric fence and it's pre
Hi Scott, I never like to guess but take a look at this video showing RFI we tracked down last year at W9RE and you will see similarities to what you are seeing and you might also gain some info/insi
Hi Scott, Yep, it was a Generac system in our case at W9RE last year, and you definitely need to work with Steve at the ARRL as he has great contacts within Generac which greatly helped us. I prefer
I've been encountering new RFI this year every 10 KHz on 80 through 10 meters and quickly (within minutes) tracked the RFI down to my neighbors house using my Portable Flag with DX engineering preamp
Here is follow up to my Oct 14th posting about RFI tracked down to my neighbors house. My neighbors house is on an adjacent street and her backyard backs up to the side of my backyard. Today I was ab
One correction, I probably should have said they were LED strip lights whereas I called them string lights. Don (wd8dsb) _______________________________________________ RFI mailing list RFI@contestin
Hi Mike, Doing some quick reading there are lots of different variants of LED strip lights, but I suspect the ones my neighbor has are low end in which all of the smarts are in the controller and the
Hi Tom, Lots of people helping you so Ive stayed silent but let me make a couple comments related to your most recent comments. If you have a radio that tunes down into the VHF aircraft band it will

Hi Wes, You can still get QST in printed form which is what I do and when you factor in inflation membership that includes the printed version of QST costs just slightly more than it did 20 years ago
