Thank you, that link was very helpful.

Very interesting! I’ve installed it and attempted to look at the mystery signal, but I cannot make
inspectrumshow anything other than red. I think it’s sampled at 225144, but that’s speculation based on the filename. Any thoughts?Source file: github.com/vk6flab/signals/tree/main/recorded

- Comment on [FoAR] Foundations of Amateur Radio - The ARRL incident of May 2024, a year later #podcast 1 week ago:
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.
- Comment on Is there something like a spreadsheet for hierarchical data structures? 1 week ago:
There’s a whole range of cli tools to extract and query structured data like that, but you might consider loading it into something like sqlite3 and treating it as a database because those formats are really not intended for queries, they’re designed for sharing data.

- Comment on To what extent has Smartphones replaced Computers? Has Smartphones replaced Computers for you or people you know? Will Phones and Computers eventually merge into one device? 1 week ago:
For some workloads it’s true that you can do the heavy lifting on a more powerful remote machine and transport the results back to an endpoint device like a phone. Websites are a good relatable example of that, as are services like YouTube.
It’s not universally applicable for many activities that computers are involved with, data analysis, record keeping, simulations and a myriad of other processes.
Blurring of the lines between these different orders of magnitude is made possible by faster and faster networks, but that’s physically not able to beat processing done inside a single device.
The more powerful we make computers, the more complex problems we use them for. I suspect that this is unlikely to change as computers evolve.
- Comment on To what extent has Smartphones replaced Computers? Has Smartphones replaced Computers for you or people you know? Will Phones and Computers eventually merge into one device? 2 weeks ago:
One of the fundamental differences between phones, laptops, desktops, and beyond is size. While that sounds obvious, it also means that the amount of processing within the device is constrained by that size.
The constraints relate to how much energy can be used by each device and more importantly, how much cooling is available for the system.
It means that there’s a physical limit on how much work each device can do without being unusable.
While miniaturization is a factor, it’s not linear and you can only get so small before you fail.
So, depending on what you want to do in any given time, the device you use will dictate what’s physically possible.

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.

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 qrm.guru to determine exactly where the noise is coming from and what to do about it.
- Comment on Should I be worried about "Prompt ejection" attacks on my gmail? 4 weeks ago:
I work in ICT. Leaving Gmail is much easier said than done. It has the best spam filtering bar none and integrates with a whole host of other services that I use daily, like the mobile phone I’m writing this on for example, the one that integrates my calendar, tasks, contacts, photos, websites, YouTube channel, spreadsheets and, oh yeah … that other thing … Gmail.
So, if wishing made it so.
What I’d like is a Google Workspace tier that is entirely without AI.

Oh … you’re a dick … thanks for self identifying.
- Comment on Why do people care so much that their friend or family member’s partner is attractive and not just loving? 1 month ago:
- I’ve been here for almost six decades.
- I don’t know what the topic of “procreation genetics” means outside this thread where I was attempting to answer OP’s question and put those two words in sequence to explain myself.
- I think that life has an imperative to procreate and has done so since it started.
- Life, as we currently know it, appears to revolve around genetics.
- I’m not sure what you’re talking about.
- Comment on Why do people care so much that their friend or family member’s partner is attractive and not just loving? 1 month ago:
I’m guessing that being gay doesn’t turn off the part that’s looking for a beautiful mate.
- Comment on Why do people care so much that their friend or family member’s partner is attractive and not just loving? 1 month ago:
I’m pretty sure that it boils down to successful procreation genetics. As in, the more attractive you are the bigger the selection of mates you have access to. It’s been happening for as long as life has existed here.
No doubt this has across history been heavily distorted by culture, art and religion and in more recent times by fashion, marketing, advertising and media.
