Taking this opportunity, I shot a video of what the experimental Russian HF hopping system looks like in the experimental 3D function from Simon. Sorry for the pun :)
In this case, these are 8ms tones that are pseudo-randomly distributed over a 100 kHz bandwidth. Parcels do not overlap in time.
Thanks to Simon for the tool, and I hope for its further development.

Probably they do match in terms of power per pixel.
The number of pixels wide makes a difference in levels.

I find it interesting, and played with it for awhile. Wasn't sure
where in the band, or band width, was showing, but comparisons
with the waterfall soon rectified that.
One thing that might help, the background noise (noise floor) does
not match that in the waterfall it seems. I need to adjust the
waterfall to see the noise a bit to help in locating signals on
the 3D - maybe some freq numbers, or other locating device could
be added? And/or a slide to adjust the background noise level in
the 3D separate from the waterfall one? Using the "Auto" button on
the left of main panel makes the 3D have zero background to help
see the weak signals, so the suggested slide or a bit more gain in
the base 3D setting may be of assistance.
Looks like a nifty addition, not sure if I will use it a lot, but
interesting to play with.
Thanks for the toy Simon!
