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.
