Last week, the International Space Station transmitted images all around the globe using amateur radio and SSTV (slow-scan television.)
These images - a collection of photos related to amateur radio on the space station -- were encoded into an audio format using the PD-120 SSTV mode. The encoded audio was then trasmitted over FM in the 2m amateur band, where it could be received by anyone and with nearly any VHF radio - ranging from proper rigs with high-gain antennas, to a cheap HT and a cell phone for decoding!
The two images below were decoded by me. The first was captured using a Yaesu FT-2900 and roof-mounted, 2m omnidirectional J-Pole, while the second was captured with a handheld HT and a cell phone running the decoder.
This event was part of ARISS, a program promoting amateur radio on the International Space Station. Amateur radio has long been linked to space exploration, and numerous satellites carrying amateur radio equipment and repeaters are currently operational and in orbit.
