No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

For those who are unfamiliar, encrypted or not radio signals can still be tracked down. Normal communication is like everyone in a room speaking English and we all understand each other. Encrypted communication is like speaking in gibberish that only a few can understand. BUT everyone in the room can still hear that a person is saying something.
Triangulation is a thing. If you become a pest licenced operators (see radio fox hunting) and maybe the FCC themselves will be able to direction find you easily if you aren't careful. $7-10k is the base rate for fines for this stuff if it came to that. If you fuck around near aviation, police, fire, or other similarly important radio frequencies you will find out VERY quickly.
fun fact lora bands (the ones meshtastic uses) are mostly outside of amateur bands and have encryption enabled by default. They don't transmit very far on their own though, they need other meshtastic devices to relay messages over longer distances. Business band licences allow encrypted radios too.
Maybe if you are in a rural area you can try it with basic FRS/GMRS walkie talkies where there isn't a licencing requirement and by extension maybe a bit more leniance if you claimed you didn't know it was against the rules.
Slight correction, Lora is shared with amateur bands, but the transmission power is low enough that it's within unlicensed limits.
Also, they can actually transmit quite far, they just can't penetrate well. A mountaintop node can communicate to the horizon, but inside a house at desk height it can struggle to reach a half mile.
True, thank you!
I'd listen to this gentleman right here. He said a bunch of shit I don't understand
He's just Some Amateur.
Oh, go bite your bike. ;p
Hell, Kevin Mitnick was caught via cellular tower triangulation all the way back in the 90's.
It's far from new technology too, so at this point you would think radio triangulation would be piss easy and cheap to do.
Agreed on the LoRa devices. I personally think the future of comms is in meshed low power high latency devices.

These take some knowledge to build, but I think they're pretty slick.
Yep, Usually people dont care until you start blasting away legit services. Then a lot of people start showing up at your door. Theres triangulation devices on https://www.tindie.com/ for amateurs that are very cheap and the pros have MUCH better equipment.
Meshtastic ( [email protected] ) is in a small range/spectrum and consolidated in LoRa. Its very unlikely to cause issues so its tolerated. Its very much a legal way to get text to a friend or community....if your local community is big enough.
FRS and GMRS have similar restrictions on encoding, and also limits or prohibitions on digital/data modes.
Ignorance of the law is not an excuse, but compliance with the letter while violating the "spirit" is generally acceptable.
