Any form of encryption on amateur radio frequencies is prohibited under FCC Rules Part §97.113 Prohibited transmissions Section 4 http://www.arrl.org/part-97-text . This makes things like TCP/IP over HAM frequencies legal (as seen here https://en.wikipedia.org/wiki/AMPRNet ) but not SSL traffic. No business transaction required.

Bitcoin doesn't use encryption. I don't know whether LN does.

LN does not either.

Interesting article, but I think Wired has to be one of my least favorite places to read something on the web. The performance is bad, there is popping/jarring of the viewport as content shifts around, intrusive pop ups, and just a generally high amount of bloat. I’m starting to feel like the old man shaking his fist at the clouds, but can we just go back to more simple pages without all this cruft?

I don't have any of the issues you are experiencing. I'm using Firefox, AdBlock Origin, Privacy Badger and containers and I don't see any ads, the page is plenty fast, no popping/jarring content.

On desktop or mobile?

If you're a registered ham, the FCC has your address, so they can fine you or revoke the license.

And if you’re not, registered hams make a game out of finding particularly egregious pirate stations and reporting them to the FCC.

Why do they do it though? It's not like the FCC is going to pay them for their time... I suppose if someone is really broadcasting garbage and disrupting communications then I can see the issue.

Desktop. Where are you having problems?

Whackers are definitely a thing. And they'll doxx and locate you in real life. And worse yet, they'll even think they have some sort of license for 'citizens arrest', or FCC reporting.

Power tripping, primarily.

Standard disruption or otherwise will usually get you caught. But sending 200 bytes that happens to be cryptocurrency isn't likely to be found, or caught... Unless you're dumb enough to do it on a repeater (that probably records and streams online).

Funny thing, out of the blue I decided to take practice tests for a ham license last night. Took the practice test about 12 times and got passing score 7 times. Opened HN today and this is one of the top articles... Interesting coincidence.

I'd encourage you to do it...

And then build this. https://hackaday.com/2019/06/05/mobile-sigint-hacking-on-a-c...

Companies have been putting radio transceivers in all sorts of devices, and almost all of them are insecure piles of rubbish. Yet because the tools to analyze them have been nearly non-existent, I designed and built the RadioInstigator.

We're just now seeing radio-fuzzing and other attacks. And I'd expect that this area is going to explode in the coming year. SigInt is now in the hands of the average joe and jane. Devices that relied on security as 'cant easily get the gear' are no longer secure. It's now just a matter of time.

This looks like a cool project. Very interesting indeed
