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
