"I am the Ghost of XM's Past" (Weird signals on shortwave)

[Swamp Thing]

(Edited per DaveC426913's suggestion)

A new kind of shortwave oddity, and some theories about what it may be.

A one of sixteen pure tones signal, called "piccolo", was used mainly by British diplomatic data links. It usually had a slightly faster bit rate than the one in the video.

The "washing machine" sounds like a combined raster, time reversal, and spectrum inversion scrambler. Maybe it is simply being used like a jammer, to keep that military channel available, in case it is needed.

It is interesting to note the presence of the signals, but do not get involved in trying to read the content, unless you are paid to do it.

It would be swell if the OP had a short explanation of what the video contains. As it is, both the thread title and the opening post are inscrutable, and readers are forced to watch the video just to find out what the thread is about.
