This was a waterfall image test to see the viability of playing music with the bandwidth lowpass filter set and at the same time being able to send images from above the lowpass cutoff frequency.

Thanks for picking them up.

OK. Here's another idea: images on the LSB and simultaneous music on the USB.

If I go that way I would do independent sideband stereo sound with images on both sides.

But yeah, if you have the bandwidth (and we know that you have a lot of bandwidth  ;D ) then combine them into one sideband.
I don't STRETCH the truth.

Via a recording

MRI (I assume that it is Mix Radio International) transmitted waterfall images on 6881 from 0117 through 0122.  Three bars superimposed over a cloud and "MRI" below.  One was sent, then a group of two, then a group of three, and, finally, a single image.

Continued with very long strings of the image through 0158.
