    My ex’s dad was a ham radio guy but this seems excessive.

    I should start making some meshtastic/meshcore devices…

      I got my Meshtastic node running tonight for the first time. I expected to be out of range because I have line-of-site to very little. My node currently shows 160 other nodes online. Woohoo!

      Already looking at another client for Meshcore.

      edit - now at 285 nodes

      My grandfather was a Ham guy, amongst a great many other brilliant things.

      One of many things I wish he’d have lived long enough for me to experience with him.

      I got into MeshCore after Benn Jordan mentioned it in a recent video. Turns out there’s already a network spanning hundreds of kilometers in my area. I’m making a couple companion nodes so I can communicate with my partner, who lives an hour away, in the event of an emergency where there’s no power or internet. Also making some solar repeaters to improve coverage in my area.

      Surely Trump will swoop in and prove he doesn’t tolerate authoritarians murdering civilians outside of the U.S. in an attempt to suppress their free speech.

      Bc if he does approve, he’s supposed to add him to the official good guyz list of exceptions along with Saudi Arabia and all the other benevolent murderous dictators. Otherwise shit just gets way too confusing.

    Fascist/authoritarian scum the world over are TERRIFIED of the concept of regular human beings having the ability to communicate with each other without being censored, coerced, and surveilled. This is a nightmare scenario for them: people speaking freely

      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.

                  It is a thousand times more easy to send a secure electronic message then to broadcast an untraceable radio transmission to someone if any physical distance.

                  Any government they is locking down electronic communication that effectively would fine your radio based solution trivial to intercept and trace.

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

            …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. :(

              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.

                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.

                Yeah sorry I meant like from different places in a city, not just not at home.

                It’s for sure rude and not something I’d try/recommend but we’re talking about espionage here.

                Am I wrong in thinking that if I wanted to propagate revolutionary thought and went to a different neighbourhood with an HT and transmitted to the local repeater, it would be hard for the state to find me if my transmission was less than 5 minutes?

                  It just takes 3 or more synchronized receive stations to pinpoint your location. The state has an unlimited budget compared to you.

                  It’s not significantly more difficult than transmitting from a mobile station.

                  We are taking about hiding from a government. They could pinpoint you in seconds.
