RS-12/13 is a Soviet amateur radio payload aboard Kosmos 2123, a Zikada series satellite .
construction
The amateur radio payload RS-12/13 is identical to the RS-10/11 . This payload was built by radio amateurs and called the "On-Board Radio Technology Complex BRTK". This complex took advantage of the power supply and permanent attachment to the platform of the Zikada satellite. Usually one payload was in operation and the other was kept in reserve. Both payloads had receivers in the 2 m band and in the 15 m band , as well as transmitters in the 10 m band and 15 m band, which could be configured to a 40 kHz wide transponder with five different modes:
- A - uplink 2 m band, downlink 10 m band
- K - uplink 15 m band, downlink 10 m band
- T - uplink 15 m band, downlink 2 m band
- KA - uplink 2 m and 10 m band simultaneously, downlink 10 m band
- KT - uplink 15 m band, downlink 2 m and 10 m band simultaneously
Furthermore, a robot autotransponder could be activated. The robot autotransponder could be called by telegraph, confirmed the call, assigned a connection number, called his name (Robot) and said goodbye. The downlink transmitters had a maximum output of 5 watts.
mission
The satellite was launched on February 5, 1991 with a Russian Kosmos-3M launcher from the Plesetsk Cosmodrome in Russia. The satellite was in operation for 11 years and 6 months and failed in August 2002. It is believed that a solar flare in August 2002 caused the satellite to fail.
