Ham radio enthusiasts revive Teletext for digital communication

An amateur radio enthusiast has recreated Teletext, an analog television data service, for use in ham radio communications. This project, named Spectel, leverages the AX.25 protocol to transmit Teletext pages as digital tones, offering a low-bandwidth, resilient communication method. The system aims to provide a digital counterpart to slow-scan television, enabling faster and more reliable text-based information exchange over radio waves. While the developer utilized AI coding assistance for the project's implementation, they express reservations about reliance on centralized AI systems for DIY endeavors.
