Reticulum Targets a Radio-Driven Post-Internet Network

Hackaday reports on The Tech Prepper's demonstration of Reticulum, a decentralized cryptographic network stack, using high-frequency radio to envision a post‑Internet communications layer that could operate when traditional networks fail; encryption bans on ham bands complicate real-world use, but the setup shows connecting a PC to an open-source radio modem and SDR tools, with BBS-style options like modem73 as possible alternatives. While appealing to survivalists and cyberpunk hobbyists, practical mass deployment faces regulatory and technical barriers.

"Throwback: Hilarious Ham Radio Memes from the 1970s"

A video showcases a Robot slow scan receiver from the 1970s, which was used by ham radio operators for sending pictures via low-bandwidth audio. SSTV-equipped hams would exchange memes and selfies on specific frequencies, but there wasn't much conversation. Nowadays, PC soundcards are commonly used for SSTV, but back then, the Robot with its 6-inch screen and $295 price tag was considered advanced. The machine still works well and serves as a reminder of vintage ham radio gear.

"2023 Cyberdeck Challenge: Building a Ham Radio CyberDeck"

A ham radio enthusiast has built a rugged cyberdeck with a Raspberry Pi 4, 10-inch LCD screen, and a rechargeable battery pack that lasts up to 20 hours. The deck features a USB software-defined radio module, a BNC connector for an external antenna, a game controller, and storage for a mouse. It is designed for use during camping trips and ham radio field days, and is housed in a weatherproof enclosure with 3D-printed parts.

"Artemis 2 crew talks mission and ham radio communication."

"Artemis 2 crew talks mission and ham radio communication."

Most of the astronauts aboard the Artemis 2 mission are certified ham radio operators, and there are high hopes in the community that the astronauts may call home from deep space. The first ham radio operator in space was NASA astronaut Owen Garriott, who called an amateur radio operator on Earth in 1983. Today's ham operators communicate with astronauts through Amateur Radio on the International Space Station (ARISS), largely aiming to let students directly talk with spaceflyers. It's unclear if ham radio equipment will be onboard Artemis 2 as the mission manifest is not yet decided.
