"The spacecraft central panel carries the DOKA-B equipment comprising
the onboard computer; receiving equipment operating in 145 MHz band;
transmitting equipment operating in 435 MHz band as well as the onboard
radio navigation equipment."
"After checking the satellite systems, the data related to the first
artificial satellite launch is downloaded. The transmission lasts for
4 minutes. Within this time the following data is downloaded:
a call signal and TM-data (10 seconds); a voice message (1 minute);
a pause (50 seconds the first artificial satellite imitated signals
(10 seconds); an image (1 minute); a pause again (50 seconds).
The onboard spacecraft data is transmitted via a radio channel in the
435 MHz international frequency band of experimental and radioamateur
communications, in cyclic mode, in narrow-band FSK mode.
Voice messages and images can be received in any place of the Earth
when the satellite floats above within the radio visibility ranges.
Any standard radio equipment can receive the signal in this frequency
band requiring no additional technical means."

Yubileiny(RS30) CW 435.215MHz !!??
I found some CW 435.215, not 435.315, accidentally by chance.
435.215MHz, object C, 09:23:00-09:44:00 UTC, 25 May 2008
Maybe I think that is Yubileiny(RS30) or an another satellite.

Yubileiny RS-30 Launched on May 23 [amsat-news]
The Russian Federal Space Agency announced the successful launch of the
Yubileiny, a 45 kg small satellite, on May 23 from the Plesetsk Launching
Site into low earth orbit.
The motive for development of Yubileiny small spacecraft was the 50th
anniversary of the first space satellite. One mission goal includes flight
qaulification of the new space systems and equipment. Radio amateur operators
all over the world will be able to receive the telemetry downlink utilizing
RS-style CW telemetry 435.315 MHz using the callsign RS30.
The satellite transmits a cyclic series of messages lasting for 4 minutes
including a call signal and TM-data (10 seconds); a voice message (1 minute);
a pause (50 seconds); the first artificial satellite imitated signals
(10 seconds); an image (1 minute); with a final pause (50 seconds).
Aerospace Vehicle Laboratory SCC is the primary the satellite control.
A similar Satellite Control Center has been established at the Siberian
State Aerospace University in Krasnoyarsk to allow students and research
engineers can receive and analyze the telemetry in cooperation with the
specialists at JSC Academician M.F. Reshetnev Information Satellite Systems
center. Details can be found on-line at:
