Reviving Teletext for Ham Radio
Summary
The article explores reviving teletext for ham radio by transmitting teletext pages over AX.25, effectively turning a 1980s text service into a modern, low-bandwidth data experiment for radio enthusiasts. It covers Teletext history, the technical constraints of teletext graphics, the proposed implementation (Spectel) using Python and AX.25 on HF/VHF/UHF bands, and the author’s experiments with vibe coding and AI assistance.
