Many thanks to SWLing Post contributor, Tom (DF5JL), who writes:


Who doesn’t know the mysterious station “The Buzzer” on 4625 kHz – but now it gets even more exciting: Because since today “The Buzzer” has a twin that transmits on 4810 kHz – fully synchronous. And to make to put a scoop on it: location is apparently near Changdu in China.

Thanks for the tip, Tom!

Yes, I noticed that our friend, Tudor Vedeanu, recently posted a recording of the new Buzzer twin on 4810 kHz:

I’m curious if the new Buzzer frequency is being used 100% of the time? Can anyone confirm?

      Exercise/tests completed, channel (temporarily ?) closed, makes a lot of sense imVVHo; if that’s the case they probably had some datalink to drive the “twin station” and using it they were able to cover a wider range (east/se pacific … hong kong … or ?)

    Not sure it’s related, but Russia and China conducted a joint military exercise called “Tsentr-2019” (adding a link below, but more infos can be found by searching)

    and I wonder if the sudden appearance of the UVB twin may be related to some kind of mil co-operation between the two countries and/or to the need of having an UVB “twin” in China to repeat signals for the exercise; I’m not a mil analyst, by the way, I’m just “connecting the dots”
