Hi, Here is a short video I made of the noise I now have on the all band. Do you have any idea where it came from? https://youtu.be/8UHDtS5w7Fw Thanks! Hugo __________________________________________

Looking at on audacity and listening too I am guessing 60/120hz power arc. But then again I have had so much of it in the past I hear it in my sleep, lol. First pull power to your house while rig is

In general, RF spectra and waterfalls are FAR more useful in identifying possible sources of RFI. See the tutorials on my website. k9yc.com 73, Jim K9YC ______________________________________________

My thoughts are the same after hearing it; sounds like 120 Hz arcing so I suggest turning off power for a one-family dwelling, and if it goes away, turning off one fuse at a time. Can't do that in an

Agreed Jim, thanks. I just have been fortunate to not need that horsepower (so far). With the 120hz gone, I am hearing some stuff occasionally that is likely from other homes nearby but its very inte

Hi, I have already closed the braker and no change. I have stopped all the UPS. I used my KX3 on battery power. No change. Here are 3 other videos including one with the waterfall that Jim was asking

The problem is that spectrum analysis of virtually any power handling electronics will also show strong power frequency components. The reason for using RF spectrum and waterfall as the first element

Hi Hugo, Quickly looking at your waterfall display on 160 and 80 meters, it looks like a repeating pattern at a frequency of approximately 6 KHz, and also a comb pattern at a frequency of approximate

Hugo, I have a few entries regarding how to set up an SDR to survey your location for RFI at: https://www.nk7z.net/sdr-rfi-survey-p1/ That process will give you the start/end times Don was talking ab

Hi, Several have asked me to make other videos showing different hours of activity and different bands. On June 8 and 9, 2021 we had a big storm that cut the entire city's electricity grid for 2 days
