very clear MRI image in waterfall seen several times; no voice signal heard (yet)
0148: waterfall images now in continuous mode

It's got a nice beat, but a little hard to dance to. Sort of like polyrhythmic synth jazz.

Frequency jumping to avoid QRM from very wideband data (?) signal.
S9+10

Thanks for the picture show!

You should cut down on the hallucinogens. If you keep going, you're going to see lipstick on cats and stuff.

Some people say I suffer from insanity. I don't. I enjoy every minute of it.

6880 USB
200- Data only here. No music that I can hear.

6855 USB
210- Funky data sounds, like Darth Vader meets R2D2, on acid.

Heard nothing on 6880 but now on 6855 hearing data sounds and seeing the following image repeated.

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.

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.
