After their release the Russian cubesats send photos in SSTV Robot 36 mode. The data transmissions use AFSK at 1145 bps with non-standard tones. It is not easy to understand the voice messages.

Some further information:
"The mission of the satellites of the SWSU series: Creation of a peer-to-peer information network. Retransmission and parallel transmission to the ground monitoring station is organized within the network.
- study of the Earth's magnetic field
- measurement of radio noise in outer space
- transmission of photos (SSTV) and voice messages (AUDIO) to radio
amateurs around the world. Each satellite will have its own personal phrase, which is translated into 8 different languages.
The Tsiolkovsky-Ryazan 1/2 satellites carry special radio transmitting equipment designed to perform the scientific task of calibrating the sensitivity of the radio telescopes of the Pushchino Radio Astronomy Observatory of the Astro-Space Center of the Physical Institute P.N. Lebedev of the Russian Academy of Sciences (PRAO ACC FIAN, www.prao.ru). Also, these satellites can emit specialized radio signals to study the effects of radio wave propagation through the ionosphere using radio receiving equipment, which is supposed to be manufactured at the Russian State Technical University and used as part of the PRAO ACC FIAN radio telescopes."

What amateur radio capabilities/experiments are these adding to the community? The radios seem capable but monoband. Will they do SSTV experiments? Packet repeaters?

On July 21 Russian cosmonaut Oleg Artemyev and ESA astronaut Samantha Cristoforetti will carry out an EVA outside the ISS. During that 7 hours long EVA, starting at around 14:00 UTC, the spacewalkers are planned to deploy ten Russian cubesats into orbit under the program of the space experiment "Radioskaf". The EVA, including the deployment of the cubesats, can be witnessed live on NASA-TV.
