I have talked to the space station on Ham Radio twice now. That involves orbital mechanics, tracking, frequency tracking. Stuff that could not be faked for an aimed, orbital radio contact. In this cover image from 2022 the ISS Commander is talking to ME on the ham radio. I can prove this no less than two different ways, and I have a verification (QSL) card from the ARISS organization. Two in fact. One for each contact I have made over the years. Here I am telling Cdr. Kjell Lindgren “Aloha from Hawaii”. My callsign is written on his notepad, and I logged the exact time this contact was made…. same as the EXIF data on when this image was made.
