Itβs Teletext, But On The Radio
Old-school teletext with its pixelated text and block graphics may now be largely a thing of the past, but that doesnβt mean itβs without enthusiasts or thereβs no more life in the idea. [M7TJF] has a project which takes teletext and puts it on amateur radio through the magic of AX.25. Itβs called CEEFAX Station, in honor of the BBCβs teletext offering from back in the day.
What you get is a Linux package or a Windows executable, which you run and presumably hook the computer up to a radio. It can either be a transmitting node or a receiving one for browsing pages, and thereβs an online map to track whoβs doing either and on what frequencies. This is all brand new so thereβs not much on there at the moment, but we expect that as people try this mode, this will change.
Sadly itβs a little unclear on how the protocol works and how the pages are encoded, but itβs early days. Meanwhile if you hanker for the real thing, itβs still about in some places.
