I can't seem to find it now, but there was a QSL card for Panda Radio and a screen shot of SDRuno with a Panda Bear clear as day. How to people create images within the waterfall.

Apparently Ham's are also putting their calls into the waterfall display.

I have also seen it on the MARS data channels. Unfortunately the one time when I saw it I wasn't ready to screen grab it. It caught me by surprise. I think it was either on one of the Air Force (AA) or SHARES net.

Another neat trick is to record some ota music and play it back ota from the image. Just for proof of concept of course.
