Are you an active LoTW user?
Very interesting! I just recorded a sample using your WebSDR, much appreciated.
Edit: Hmm … that’s odd. I just managed to check the file, two days later, and it’s essentially empty. It doesn’t appear to have saved the .mp3 file at all.
That’s very interesting. I thought it was a once-off, but you appear to be saying that it’s ongoing. I currently don’t have HF capabilities, so I reported on a recording made by a fellow amateur.
As far as figuring out where it comes from, the direction finding can be pretty rudimentary. Use any directional antenna and determine the direction of the strongest signal. Document it somewhere, get multiple people across the globe to do it, job done.
Feel free to record them here, seems like as good a place as any.

I’d recommend you explore https://qrm.guru/ to determine exactly where the noise is coming from and what to do about it.

Disclaimer: I’ve only just started looking at it for a different use-case, but it seems like it will do what I’m suggesting.

I run projects inside Docker on a VM away from important data. It allows me to test and restrict access to specific things of my choosing.
It works well for me.
Some of it is still in a museum.
I’m fluent in Dutch and at no point in the supplied link is there any reference to eating anything.
Attempted murder, torture, court, death, body parts being sold, heart being cut out and displayed for years, yes … eating, not so much.

The SCSI solution requires making sure that you have the right terminator connector because of course there’s more than one standard … ask me how I know … I think the Wikipedia article on SCSI says it best:
As with everything SCSI, there are exceptions.
It might be an idea to raise the issue with your member society directly. Their “official” contact details, and that of every society is here:
The Wikipedia page of societies is here:
So, your eyeballs already do this … that is, convert radio frequencies into electricity.
That you posted in this community means that I am going to assume that you understand that light and radio are the same thing. This means that anything that can “detect” light is essentially an antenna, for that (range of) frequency(ies). The Charge Coupled Device sensors or CCD sensors are in common use in digital imaging, it’s an integrated circuit that can detect light. Or said differently, a CCD can detect radio waves at light frequencies.
In other words, a CCD chip is an array of antennas, that do what you describe.
I’m not sure what a densly packed array of nanoscopic antennas brings that isn’t already solved with a CCD.
CCD’s are also used outside the visible spectrum in all manner of places.

The lack of transparency within the various bodies within our community is disturbing. It’s not that the information is there, waiting to be found, instead it seems clear to me that it’s been withheld for reasons nobody has ever even attempted to articulate let alone justify, and frankly I think it’s harmful to the well-being of the entire pursuit of amateur radio.
