http://ariss-sstv.blogspot.com/ published an update to the December MAI-75 SSTV testing schedule (originally scheduled over Moscow and adjacent areas):

**UPDATE - Nov 28** Seems the system will be put through some extended testing from December 5 starting around 15:00 UTC and running until 09:00 UTC on December 6. Test images will be used during this period. This will provide near global coverage if all works well. 145.800 MHz.
