Mystery noise at about 1428.440 kHz visible across the US.
« on: October 22, 2023, 0043 UTC »
I noticed this noise appear some time back (don't recall how long ago) at about 1428.440kHz. I assumed it to be some local noise from the neighborhood, until I saw the same noise on another KiwiSDR located on the other side of the metro. Poking around other SDRs, I see this noise throughout the midwest and down to the Crowley, TX sdr where it appears to perhaps be the strongest. It doesn't appear on KiwiSDRs in Europe and Asia so it's likely not a spur from the Kiwi or Beagle.

Anyone have any ideas? Anyone see it where you're at?


My SDR.
