Just from what I hear on the video, I would say a few things: 1. It sounds like it's around 9600 baud. 2. It sounds sparse. 3. At that bit rate, that amount of data doesn't contain an image. My guess would be that one track is commands being sent or telemetry being received, and the other track is maybe an operator explaining what he's doing or commenting on the decoded telemetry. Edit: I had the Russian guy in the next room translate some of it, and it sounds to me like there's a burst of data, then a comment about things like "device is on", something about lights, etc., so I'm going with the return telemetry one. Maybe they were also getting video, but it's on a different channel.
