The amateur radio CubeSat OSSI is planned to launch in December according to an Antara News article. [UPDATE rocket launch has been delayed and may now be April 2013]
The article describes how Korean artist Hojun Song DS1SBO developed his own home made satellite and says radio operators will be able to communicate with the satellite. If all goes well, it will repeat a message in Morse code using its LED lights at a set time and location.
The DIY satellite OSSI is planned to launch on a Soyuz-2-1b from the Baikonur launch facility in Kazakhstan in December with the Bion-M 1 and Dove 2 satellites. (The Dove 2 CubeSat will transmit images on a 2.4 GHz downlink). The satellites will be placed into an orbit with an apogee of 575 km, perigee of 290 km and inclination of 64.9 degrees. They are expected to remain in orbit for about a year before burning up on re-entry into the Earth’s atmosphere.
The OSSI uplink is in the 145 MHz band and the downlink in the 435 MHz band.
