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

A new shortwave signal, referred to as "piccolo," has emerged, characterized by one of sixteen pure tones and historically used by British diplomatic data links. This signal typically operates at a faster bit rate than shown in a related video. Additionally, a sound described as "washing machine" is theorized to be a combination of raster, time reversal, and spectrum inversion scrambling techniques, possibly functioning as a jammer to maintain military channel availability. The discussion emphasizes the intrigue surrounding these signals but advises against attempting to decode them unless professionally engaged. The initial post lacks clarity, leaving readers to watch the video for context.

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.
