Virtual Railfan YouTube channel will give you most of them.
Makes you wonder if Tesla used YouTube as a training tool.

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.

Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•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?1·11 days agoFor 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.
Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•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?14·12 days agoOne 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.

Are you an active LoTW user?
Onno (VK6FLAB)@lemmy.radioOPto Amateur Radio@lemmy.radio•[FoAR] Foundations of Amateur Radio - The Art of decoding a signal. #podcast2·13 days agoVery 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.
Onno (VK6FLAB)@lemmy.radioOPto Amateur Radio@lemmy.radio•[FoAR] Foundations of Amateur Radio - The Art of decoding a signal. #podcast2·16 days agoThat’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.

Onno (VK6FLAB)@lemmy.radioto No Stupid Questions@lemmy.world•Should I be worried about "Prompt injection" attacks on my gmail?102·26 days agoI 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.

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.
And Olijfje for Popeye’s girlfriend…
And Olijfgroen for the colour.
