it’s illegal to transmit anything encrypted unless you’re controlling a satellite
True, it helps to ensure nothing illegal is going on and enforce keeping commercial interests out. It’s a self regulating space, one of the only cases I know of that tends to work due to there being no monetary interests allowed. The point is to communicate information, not hide it.
it’s illegal to transmit anything for commercial purposes.
True, the whole point is to keep commercial interests out. That’s what “amateur” means.
illegal to transmit anything on a regular basis that could reasonably be communicated some other way.
False. This is for something like a non-profit wanting to use radios for their operations, they should be steered toward another service like gmrs, FRS, murs, etc. instead of amateur radio.
There’s a difference between encryption and encoding, and that difference is intent.
Encoding is the process of imparting a digital message onto the radio carrier. A simple example is Morse code; transmitted by keying a continuous wave on and off in pre-determined patterns of long and short pulses with long and short gaps between. Frequency shift keying and bodot code are the encoding scheme behind RTTY, etc. Hams are permitted to experiment with novel encoding schemes, and have invented a few, PSK31 comes to mind, a phase shift keying standard designed to use commonly available PC sound cards as a modem.
Encryption is the process of obscuring the message for all but the intended recipient. There is one specific case the law calls out when this is permissible in Amateur radio service, and that’s control signals of Amateur radio satellites. A novel encoding scheme, like making up your own alphabet instead of the standard Morse one, or ciphers of any kind that are intended to make the message secret, is illegal.
It’s not uncommon to hear encrypted communiques on the ham bands; I’ve picked them up myself. You want a fun rabbit hole to fall down, look up numbers stations. Some serious cold war james bond bullshit.
I don’t believe it is legal to send a PGP encrypted message over the air (on ham radio, go ahead and send it over Wi-Fi, you can encrypt the shit out of that) even if you’ve posted your private key on your website. What would even be the point of that? tilts head It might be legal to send a PGP signed message over ham radio; if I understand correctly that’s basically a checksum that can guarantee the sender’s possession of a private key.
And intent is functionally impossible to prove, but endlessly arguable and a judge can make a finding based on their judgement - something very different from proof.

Oh the legal system is pretty good at deciding intent, I mean what’s the difference between manslaughter and murder?
Thing is, it’s not like there’s radio police that are going to pull you over for encrypting. Other hams might turn you in if you’re being annoying. If you send an encrypted email over Hamlink once, or say something like “Beefy Burrito this is Enchilada, the tamales are in the basket” on 33cm once, probably nobody’s gonna notice.
There’s only ~3.7MHz worth of bandwith on the HF bands, another 4MHz on 6m. There’s a lot of attention on the bands that propagate. If you want to secretly communicate with people, use Reddit, or the Fediverse.
You know r/kitty? One of a trillion cat subreddits that had a gimmick that the only written word allowed was “kitty.” All post titles and comments had to consist only of “Kitty.” Arrange with the leaders of the other terrorist cells you’re working for that if u/chudmuffin posts a picture of an orange cat, we attack at dawn, and if he posts a picture of a grey cat, lay low they’re onto us.
Encryption is legal and standard on the internet, where there’s many orders of magnitude more traffic than on the ham bands. I can’t send an encrypted email over Hamlink with a license, but I can host a Tor site without one.

I wouldn’t say it’s good at determining actual intent, just good at deciding what intent is going to be assigned by the system.

I’ve always wondered how much steganography is in practice - if it’s being practiced well, nobody knows. Setup a HAM station that snaps a photo at sunset and a couple of other random times per day. Transmit the photo in a standard, open digital mode, but hide your message in the noisy lower bits of the 3 color channels 0-255 R G and B, you can easily modify 6 bits per pixel without visually distorting the image, drop that to 1 bit per pixel and nobody who doesn’t know your scheme could ever find it. To the local hams, it’s three chirps a day, with a reliable pretty picture of the sunset and a couple of more varied times. As a utility channel, that’s three opportunities per day to secretly communicate something to a listener that nobody can identify. If the picture is just 2MP, that’s 250kBytes of bandwidth per image.

Absolutely, though the “listeners” there are more readily identified, even via Tor.
Well on some popular image board like one of the hundreds of cat subs on Reddit, how do you identify a “listener” who is looking for a particular user to upload a picture of an orange cat? Thousands of people will view that post perfectly innocently.
The point is: IP addresses that download the content are traceable (and spoofable, but that leaves trails too…) Yeah, you might be one of thousands, but every day you log in you increase your odds of being spotted.
Listening to longwave radio? Yeah, basically anybody anywhere on the planet with a receiver. Even local broadcasts it is nigh impossible to know who is listening where within the broadcast radius and the average person walks around with several radio receivers on them all the time now.
True, for obvious reasons

I call bs on the encryption part too. You just need to publicly post the key for your encryption and say you’re not trying to hide what you’re saying.
I haven’t seen any regulations saying where you need to publicly post the key.
I say license up now and learn it how the shit works. Never know when some “pirate” stations may be needed.

Over here in Germany encryption is most definitely illegal. This includes encoded messages only the intended recipient could decode.
