More fun on HO-68! During a low elevation pass, Mike DK3WN and Henk, PA3GUO made the very first SSTV contact via HO68 – linear transponder. Images were transmitted between the two radio stations in Germany and The Netherlands. Signals were transmitted to HO-68, which was 1200km above earth and about 8000km distant from the radio [...]

I keep thinking that I should build one of these, but have never gotten around to it. Bookmarking this interesting link for future reference: Build Your Own 3D Scanner: Optical Triangulation for Beginners. Build Your Own 3D Scanner: Course Notes View more documents from Douglas Lanman.
I don’t really have the hardware to effectively transmit to satellites in linear transponder mode. To really make it straightforward, you probably would like to have a computer to handle the Doppler tracking and antenna pointing, and a full duplex SSB transmitter (or a pair of ordinary ones). That’s more than I am willing to [...]
