A quick sweep of the range from 0 to 198 kHz.

A quick and dirty sweep of the range from 0 to 198kHz today reveals a range of fascinating signals, from communications with submarines by the world's navies on the left, to BBC Radio 4 on Long Wave on the right. The screenshot is of an SDRPlay RSPduo, using a PAR0DT mini-whip aerial on the roof. This is where art meets radio science, I find these screenshots very aesthetically pleasing. What do you think?
