CEEFAX and TeleText

[ https://www.youtube.com/watch?v=ICoj8mxG0ww | https://www.youtube.com/watch?v=ICoj8mxG0ww ] Boy does this bring me back... I feel old... look at that "remote control"... he updates news headlines by calling up old ones and "overtypes" the previous ones... and around the 7 minute mark his entry of graphics shapes reminds me just how cumbersome this all used to be... but at the time, it seemed miraculous... (note he talks about outputting the graphics to "puncher" tape ("punch tape" in the US) that he'll THEN feel into the computer)... the machinations we went through to accomplish things that seem so rudimentary now is timeless.. later the lady talks about "content" regarding whether CEEFAX will take off - same thing the business arms are concerned with today; no change there... it just keeps getting better and better as the video goes on...

do you have any MIL-17-C RG-214 coax?
by Ken Alker 14 Jan '25

I am going to build all new patch cables for the WB6OBB repeater system and I'm wondering if anyone has any surplus MIL-17-C RG-214 coax (or equivalent) laying around they would be willing to part with. This is double shielded silver plated coax that is good for repeater systems in high-RF environments. Thanks! Ken

Santa Barbara Wireless Foundation, Inc. AN EXQUISITELY BEAUTIFUL SYSTEM Tracked early morning flight by CALSTAR Air Ambulance EC-135, N832CS +P2, with patient from San Luis Obispo landing on top of Cottage Hospital at Pueblo and RTB at Santa Maria. Satellite background photo adds to the perfect accuracy of our combined ADSB tracking system. We need to record these events and data for replay when they happen. Its worth every nickel we put into it. Bill Talanian
