Gary Pearce KN4AQ has released the video of the Digital Communications Conference presentation about the AMSAT payload for a geosynchronous satellite 

AMSAT-NA is developing a “hosted payload” for a spacecraft that Millennium Space Systems (MSS) of El Segundo, California, is under contract to design, launch, and operate for the US government. 

The satellite’s potential footprint could extend over the US from the Mid-Pacific to Africa.

The amateur radio payload will comprise a Software Defined Transponder capable of supporting many different modes, including analog SSB.
