Reminds me of US’s “HFGCS”[0] which also sends [apparently] OTP’s, though from many stations (and on multiple frequencies) simultaneously.
I imagine the continuous “buzzer” sound from the Russian station acts as both a way to keep the frequency in use, but also so that listening stations can determine if they are able to receive the Buzzer station properly. Easier to tune in if you have a constant carrier (or whatever) to look for.

- op00to 3y agoHFGCS is far more "interesting" to listen to than numbers stations because there's actual traffic. It's also transmitted from multiple locations, so it's much more likely you'll be able to get a signal. Google a WebSDR and get to listening!
- amatecha 3y agooh yeah, I've heard a couple HFGCS transmissions w/my Yaesu FT-857D[0]! It's especially ominous-souding when the sound "echoes" because you're picking up more than one station simultaneously, each at a substantially different distance!
