[Spooks] UNID digital signal transmitting on The Buzzer frequency at 4625 kHz (long recording)

[Curt Rowlett]

45 minute recording of the unusual digital signal transmitting on the
UVB-76 "The Buzzer" frequency of 4625 kHz: https://youtu.be/ldGnS0PkpQE   I
monitored 4625 kHz for about two hours during the morning. The normal
"buzz" of the signal cannot be seen or heard under the digital
transmission. That leads me to believe that the typical "buzzer" signal has
been shut off while this transmission is taking place (which, in turn,
leads me to believe that this is not jamming or interference, but a
purposeful transmission of some sort). The digital signal being transmitted
kind of, sort of resembles a STANAG 4285 signal in some aspects, but not
wholly. Perhaps a STANAG variant? Date and time visible on the UTC widget
running at top right of video screen. Tuned via the KiwiSDR located in
Mala, Sweden: http://aspliden.mooo.com:8073/?f=4625usb
