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.

QSL … thank you.

Just to make sure, you’re not an ARRL member?

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.

With?

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.

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:

• https://www.iaru.org/reference/member-societies/

The Wikipedia page of societies is here:

• https://en.m.wikipedia.org/wiki/List_of_amateur_radio_organizations

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.

• https://en.wikipedia.org/wiki/Charge-coupled_device

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.

Education.

About that.

Just because I’ve done it this way and haven’t had issues, doesn’t mean it’s the best or only way.

You dared to ask a question and the tools to explore answers are readily available.

This is how we as a society make progress.

Please don’t feel like my experience is the final answer to your question … my experience tells me that this is rarely … if ever … the case.

So … please … explore!

If you genuinely attempting to quantify this, you can create a swap file of any size right there on your drive. You could iterate and test every setting for every scenario. You could even change settings dynamically if you wanted to.

That said, I leave it to the kernel to figure out and over the past 25 or so years that’s been fine.

I’m assuming you’re familiar with Asahi Linux?

It’s still very much a work in progress.

At the moment I’m bridging the gap by using homebrew, UTM, ssh into local hardware and shortly remote desktop on EC2.

It’s far from ideal, but that’s where I found myself after my x86 iMac died last year, so I feel your pain.

I’m not sure if you’re being sarcastic, observant, or something else. There have been many a meal where I was asked what I wanted to eat and it’s rare that I go beyond the words “surprise me”, knowing full well that the person asking would eat the same as I was offered, making the “surprise”, less of a risk and more of an adventure.

In this case, OP asked a completely unanswerable question to which there was absolutely no reasonable answer, since we know nothing about the person, their interests, their experience, the hardware they have access to, or anything remotely resembling a needs analysis.

So, even my answer, generic and random as it might appear, was based on how I use a computer, namely, to be productive. I’ve been using them for over 40 years, mostly like that, with some sojourns into art and personal expression, not nearly worthy of public scrutiny, but not specifically “productive” as such.

So … what were you attempting to say?

Whatever you need to be productive.
