MAI, the Moscow Aviation Institute, http://en.mai.ru/, will be conducting their SSTV experiment from January 30 – February 1. From the scheduling, it seems that the experiment will only be active during a few orbits in Moscow range, and not in a continuous mode. Time periods of activation seems to fall between the hours of 13:00 – 19:00 UTC. Activity should occur on the traditional 145.800 MHz FM downlink.
