About RS15
RS-15, also called Radio-ROSTO, is a Russian amateur radio satellite launched on 26 December 1994 on the first orbital flight of the Rokot-K rocket from Baikonur. It was built from a surplus Strela-1M military communications satellite, and was meant as a forerunner of a constellation of Radio-M amateur satellites that was never built.
Its payload was a Mode A linear transponder: uplink 145.857–145.897 MHz, downlink 29.357–29.397 MHz on 10 m, with an output power of 5 W.
RS-15 flies much higher than most amateur satellites, in an orbit of about 1,900 by 2,160 km, which gives long passes and very wide coverage. Gunter's Space Page noted around 2015, more than twenty years after launch, that its solar cells still powered the beacon whenever the satellite was in sunlight.
