"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."

Object 32957E is probably the spent LV so Yubileiny is probably one of the remaining clustered objects.
70cm downlink frequency as yet unknown.
