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. 
Related to "I am the Ghost of XM's Past" (Weird signals on shortwave)
What is "I am the Ghost of XM's Past" in the context of weird signals on shortwave?
This phrase, "I am the Ghost of XM's Past," refers to a mysterious or unexplained signal intercepted on shortwave radio frequencies. It is often associated with number stations or other anomalous transmissions that have unclear origins or purposes. These signals can be part of the broader spectrum of enigmatic broadcasts that enthusiasts and researchers encounter in the shortwave radio band.
What are shortwave radio signals and how are they used?
Shortwave radio signals are transmissions that use frequencies typically in the range of 1.6 to 30 MHz. These signals are capable of traveling long distances, including internationally, due to their ability to reflect off the ionosphere. Shortwave is used for broadcasting voice and music to international audiences, as well as for communication by military, diplomatic, and maritime services. It is also a popular medium for hobbyists and amateur radio operators.
Why would someone refer to themselves as a "ghost" in a radio transmission?
The term "ghost" in the context of radio transmissions often signifies that the signal or the broadcaster is operating unofficially or clandestinely. It can also imply that the transmission is an artifact from a previous era, echoing older broadcasting methods or content. In some cases, it might be used to create an aura of mystery or intrigue around the broadcast.
Are these signals related to espionage or secret communications?
While not all mysterious or unexplained shortwave signals are related to espionage, a significant number of them, particularly number stations, have been historically linked to intelligence and spy operations. Number stations are known for broadcasting strings of numbers or letters, believed to be coded messages intended for operatives in foreign countries.
How can one listen to or track these weird shortwave signals?
To listen to or track weird shortwave signals, one needs a shortwave radio receiver, which can be either a standalone unit or a software-defined radio (SDR) that uses a computer for processing signals. Enthusiasts often use frequency guides and online forums to share information about active frequencies and times of broadcasts. Tools like web-based SDRs allow users worldwide to tune into and explore the shortwave spectrum without needing physical radio hardware.
