Mysterious Chinese signals on our bands

Since Oct. 25th we are suffering from mysterious Chinese signals on 7000, 14000, 21000 and 21010 kHz. At first the A3E signals were sounding like grunt or moo. Now we are receiving very strong multitone signals with a carrier and both sidebands every morning. The signals are also audible on 8000, 15000 (disturbing the time signal from RWM Moscow), 18000, 19000 and 20000 kHz. The purpose is unknown, perhaps a special kind of encrypted broadcast or a new generation of OTH radar? Please inform your national PTTs for official complaints! I informed the German PTT on Nov. 12th. The Dutch,  Austrian and Swiss PTTs are informed, too. Many thanks to HB9CET for excellent observations and support! For further details visit our external homepage: http://www.iarums-r1.org and look under "Latest Intruder News". There you can find screenshots and links to my recordings.
