The camera on AO-92 is only active when commanded by the ground team and does not use the DUV, but rather "takes over" the downlink and uses a wider signal.

Adjustment to your SDR software is required when a camera download is active. The normal settings that one might use for voice and/or DUV data will not work for the camera downlinks.

Here is a screen shot of one SDR app (HDSDR) where you can see the 20k of RF bandwidth and 15k of audio output bandwidth being used to successfully received data from the camera when it was active.

Of course the FoxTelem software needs to be set appropriately as well to accept the wideband data. "Auto" is the best setting since it allows the FoxTelem dashboard to work with both DUV data or broadband camera downlinks when they are active.

Someone else might be able to confirm the status of any other cameras currently active or planned for future missions.

Is the camera turned on? I was planning on using HDSDR and FoxTelem. I think that there are data packets sent as Data Under Voice (DUV) in the audio band from 0 to 200Hz in the same FM channel as the transponder audio. Can you really receive an entire image during a short satellite pass in that little bandwidth? Do other Oscar satellites have cameras?

The camera is turn on occasionally by ground command. When it is on, the data rate is faster and takes up the entire downlink.
