‼️‼️ Absolutey HARAM radical cryptographic wireless mesh networking guide ‼️‼️

Okay, now that I have your attention you can check out this article I wrote. Spent quite a lot of time on it as it included a lot of testing in my lab 🥼.

If you're into:

Then you're definately my type, but you should probably read this article first.

Have to get on the #meshtastic train.

My curiosity about the new Meshtastic 2.6 UI served as an excuse to pick up a T-Deck. I suppose I can also rationalize this as a testing device, but really I just think they're cool.

Riticulum is badass

Reticulum is the cryptography-based networking stack for building local and wide-area networks with readily available hardware. It can operate even with very high latency and extremely low bandwidth. Reticulum allows you to build wide-area networks with off-the-shelf tools, and offers end-to-end encryption and connectivity, initiator anonymity, autoconfiguring cryptographically backed multi-hop transport, efficient addressing, unforgeable delivery acknowledgements and more.

The vision of Reticulum is to allow anyone to be their own network operator, and to make it cheap and easy to cover vast areas with a myriad of independent, inter-connectable and autonomous networks. Reticulum is not one network. It is a tool for building thousands of networks. Networks without kill-switches, surveillance, censorship and control. Networks that can freely interoperate, associate and disassociate with each other, and require no central oversight. Networks for human beings. Networks for the people.

Reticulum is a complete networking stack, and does not rely on IP or higher layers, but it is possible to use IP as the underlying carrier for Reticulum. It is therefore trivial to tunnel Reticulum over the Internet or private IP networks.

Having no dependencies on traditional networking stacks frees up overhead that has been used to implement a networking stack built directly on cryptographic principles, allowing resilience and stable functionality, even in open and trustless networks.

No kernel modules or drivers are required. Reticulum runs completely in userland, and can run on practically any system that runs Python 3.

TollGate has a beautiful website now thanks to nprofile1qqs9pq5cgjq08vncjxzq5gph2ynnj9yk0rhu9tycrj5v6qtdqgcyalgpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsz9thwden5te0v4jx2m3wdehhxarj9ekxzmnyqyxhwumn8ghj7mn0wvhxcmmvwk2ewl!

The new modular nostr based architecture is also progressing rapidly thanks to nprofile1qqsthdwa5rs42euhnuz5xsrmmssr84hshwes7uj392vpeldj7z0zw3cppemhxue69uhkummn9ekx7mp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qg3waehxw309ahx7um5wgh8w6twv5hsef7u3d and nprofile1qqs2nprlh3rtdsgfwyg7mmsjxkjzr7msjj3achku5fjppu0qf4ae70gppemhxue69uhkummn9ekx7mp0qydhwumn8ghj7mn0wd68ytn0wfskuem9wp5kcmpwv3jhvtcpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhsftzpkd.

Stay tuned for a big release with an app that handles the interaction with TollGates on your behalf and a modular nostr based architecture that runs on your TollGate.

Ham radio operators. Imagine the decentralized comms possibilities.

Took some packet system redoing and work, but I am happy to announce that #hamstr now works great on 1200 baud packets FM using 2 cheap handheld radios and small USB audio interfaces!

Range is very limited on handhelds, maybe 5-8 miles, but great proof of concept. Fantastic for off-grid fast deployment no grid client needs.

HF 300-600 baud packets radio and VHF/UHF 1200 Baud working.

Will do a bit more testing and tweaking then merge the changes.

Using 2 50watt mobile ham radios and small 2m/70cm antennas and you should be able to use hamster at ranges of 15-30 miles with line of sight.

A great alternative to the current HF only system!

Has anyone investigated the possibility of building a LoRa-like low-power transceiver for 49.82-49.90 MHz band for use as an #RNode? This might have greater range in rural, tree-covered areas that limit 800/900 MHz signal propagation.

( Quoting from the https://www.hfunderground.com/wiki/index.php/Part_15 )

The 49.82 MHz to 49.90 MHz band allows for personal hobby transmitters up to 100mw output with any modulation as long as the modulation stays within the 49.82-49.9 MHz band. This provision within Part 15 opens up opportunities for 49 MHz beacons, provided an effective antenna is used.

§ 15.235 Operation within the band 49.82–49.90 MHz. (a) The field strength of any emission within this band shall not exceed 10,000 microvolts/meter at 3 meters. The emission limit in this paragraph is based on measurement instrumentation employing an average detector. The provisions in §15.35 for limiting peak emissions apply. (b) The field strength of any emissions appearing between the band edges and up to 10 kHz above and below the band edges shall be attenuated at least 26 dB below the level of the unmodulated carrier or to the general limits in §15.209, whichever permits the higher emission levels. The field strength of any emissions removed by more than 10 kHz from the band edges shall not exceed the general radiated emission limits in §15.209. All signals exceeding 20 microvolts/meter at 3 meters shall be reported in the application for certification. (c) For a home-built intentional radiator, as defined in §15.23(a), operating within the band 49.82–49.90 MHz, the following standards may be employed: (1) The RF carrier and modulation products shall be maintained within the band 49.82–49.90 MHz. (2) The total input power to the device measured at the battery or the power line terminals shall not exceed 100 milliwatts under any condition of modulation. (3) The antenna shall be a single element, one meter or less in length, permanently mounted on the enclosure containing the device. (4) Emissions outside of this band shall be attenuated at least 20 dB below the level of the unmodulated carrier. (5) The regulations contained in §15.23 of this part apply to intentional radiators constructed under the provisions of this paragraph. (d) Cordless telephones are not permitted to operate under the provisions of this section.
