agree on uncensorable but keep in mind ham radio is antiprivate by design - every time you say your callsign you sign off

you're also a shining beacon every second you transmit and even states with moderate capabilities record their radio spectrum 24/7 even during peacetime

I've seen tests where a reasonably equipped military vehicle could not detect a drone in the air near them transfering video, because the data link was roving through a band of several gigahertz at a thousand hops per second.

If you stay close to the noise floor, especially if you use parts of spectrum that others are using (very impolite, but people who don't want to be caught are unexceptionally impolite)... good luck to the catchers. Especially if the signal occurs at a pre-agreed time and remains short (read: don't try sending video, send something SMS sized).

Good luck sending an e-mail that can't be filtered and blocked or traffic analyzed, even if the content is encrypted.

As a minimum before trying, I would advise a peer to peer mix network (TOR, I2P). But repressive governments block those as well as they can, and may pay users a visit if they suspect something.

Pretty stupid when you are literally broadcasting a radio direction finder beacon directly from your home out to the entire world.

[-] perestroika@slrpnk.net 4 points 3 weeks ago* (last edited 3 weeks ago)

...broadcast it upwards with a reasonably directional antenna, reflecting off the ionosphere.

...broadcast it from a solar powered relay station which you access via optical link from distance.

(Not a ham radio operator, but an anarchist, but I can draw a Doppler radar in GnuRadio and have implemented a monopulse tracker... with lots of help from other people who know better. My assessement: it's easy to track powerful signals on an expected frequency, but very hard to track weak signals which do agile frequency hopping with a random key, or hide among other traffic.)

I feel sad for the Belarusian ham radio operators, however. In case of crisis, they would be the people who could help develop something interesting to help others. They were practising their hobby openly and became targets because of that. People who do clandestine business don't exchange contact information openly.

I guess KGB (they still have it) decided that nothing interesting is ever needed in their land. :(

agile frequency hopping with a random key

No kidding.

[-] bearboiblake@pawb.social 1 points 3 weeks ago

Dude you can just encrypt a radio broadcast if you want to do private comms over radio

[-] UnspecificGravity@piefed.social 1 points 3 weeks ago* (last edited 3 weeks ago)

You don't seen to understand what the word "broadcast" means and you should probably stop pretending to understand how radio transmission works.

Your recommendation is essentially to not transmit in a way that anyone can receive and therefore you can't be caught. I can give you a simpler plan to achieve that: turn off your radio.

[-] perestroika@slrpnk.net 0 points 3 weeks ago* (last edited 3 weeks ago)

Yes, let's nitpick words. Broadcast implies that something is available to others. An ionosphere reflection definitely is. An unmanned pirate station also is. An agile frequency hopping signal conditionally is - if others know a key. Which would arguably make it unicast, a term I should have used in that part of my sentence.

and you should probably stop pretending to understand how radio transmission works

Oh highness, thou areth much holier than me indeed, I am humbled by this mere sentence.

Your recommendation is essentially to not transmit in a way that anyone can receive

I made several recommendations.

[-] UnspecificGravity@piefed.social 1 points 3 weeks ago

Imaginary bullshit isn't actually useful to anyone.

[-] TheTimeKnife@lemmy.world 2 points 3 weeks ago

Most hams do, its part of the culture, experience and fun.

[-] 4am@lemmy.zip 1 points 3 weeks ago

I think HAMs are required to?

[-] gallopingsnail@lemmy.sdf.org 9 points 3 weeks ago

It's the law, every 10 minutes in conversation and at the end of every contact, at least in the US.

[-] village604@adultswim.fan 0 points 3 weeks ago

It's laughably easy for them to track you down if you don't.

[-] fullsquare@awful.systems 1 points 3 weeks ago

ranked competitive version is called foxhunting and even kid can do it

[-] m0darn@lemmy.ca -1 points 3 weeks ago* (last edited 3 weeks ago)

Not with a handheld that you don't use at home. But correct me if I'm wrong.

[-] village604@adultswim.fan 1 points 3 weeks ago

You can still be tracked while broadcasting.

It is, though. Finding the source of a radio signal is a trivial task for a government. They currently do it all the time.

Heck, it's so easy that it's a legitimate competitive sport that some grade schools use in their PE program.
