Radio amateurs at the Chertsey Radio Club have received test transmissions by two satellites inside the International Space Station (ISS)
Early in July 2017, the International Space Station sent greeting messages in Russian, English, Spanish and Chinese, which were picked up by club members.
The messages were sent during test transmissions from two small experimental Russian amateur radio satellites, known as Tanusha-1 and Tanusha-2. They will be deployed from the ISS during a spacewalk in August.
As part of the celebrations for the 20th Anniversary of Amateur Radio on the International Space Station (ARISS), the ISS sent a set of 12 images using slow scan television (SSTV). The transmissions took place over four days from July 20.
Chertsey Radio Club member James Preece M0JFP was able to receive the signal and convert them into images using a Raspberry Pi 3.
