The Russians still use a hell of a lot of HF. For the Russians it is tried and tested and an essential back-up for use in an EMP environment and especially with Morse Code. Their Morse networks are still very active.
UVB-76 uses the same format for its flash priority codeword message as do the other Russian Military Networks.
The clue is in the Russian Navy set up. Using fixed callsigns these have been easily identifiable for decades. Note the format of the Flash Message which is exactly the same as the flash codeword pattern on UVB-76.
The institute webpage that features the Buzzer frequency is simply using a constant known signal that is transmitted on 4625 khz. The buzzer has been transmitted on that frequency for decades as is a standard set frequency and know quantity. The institute is simply using it as a set and unvariable standard. The purpose of UVB-76 is a simple and effective command and control broadcast. The frequency used as constant indicates its purpose is within the Moscow Oblast region. If it used higher HF or regularly switched for propagation conditions then it would serve a purpose outside the region that it is located.
UVB-76 is not the only Russian command and control broadcast that utilises a unique and constant carrier in order to keep the frequency maintained and open. These other known broadcast networks are regularly active in the same codeword message format exhibited by UVB-76. The clue is in the traffic sent. The only mystery about UVB-76 is that the codewords broadcast are few and infrequent compared to others.
All the Russian broadcasts follow the same pattern with their codeword and priority traffic. The carrier is interupted and the codeword is sent. Note the codeword traffic sent on UVB-76
Note the codeword format used. UVB-76 93 882 NAIMINA 74 14 35 74
It is exactly the same format as used on other Russian military networks in both Morse and Voice.
Dedicated radio enthusiasts have been monitoring these Russian Military networks for years and building up the picture. It is a tried and tested, simple and effective command and control system used by all Russian forces. This includes the Russian Civil Defense network now superseded by the Ministry of Emergency Situations in the 1990s.
The flash message pattern as transmitted on UVB-76 follow the same format as observed on other Russian networks. The same format is used on the other Russian voice networks such as 'Squeaky Wheel' and 'The Pip'. See later links.
As you can see the frequency range covers all the the HF band. Note the VLF transmissions in order to broadcast to submerged submarines. One of the most active carrier maintained stations is REA4. Unlike UVB-76 is utilises a number of HF frequencies. The frequencies in use are maintained with revolutions. REA4 is probably the most active Russian Morse broadcast that regularly sends flash priority traffic in the same format as UVB-76. The radio enthusiasts who monitor the Russian networks regularly note the codeword activity being passed over the networks within an active time frame. Passed down from a broadcast and noted on simplex and complex networks with outstations repeating back the codewords in order for the control to verify correct receipt.
You can see from Russian radio scanner forum that some of the Russian conscripts knew of the Buzzer being set up on their radios. The radios were located in military bases in the Moscow Defence Region and fulfilled an emergency communications system.
Remember that the Buzzer isn't the only broadcast station in Russia that sends out the same format voice messages. Other stations such as the 'Squeaky Wheel' and 'The Pip' also function in the same manner.

The Russian Navy still use Morse to control their fleet of Naval Transport Aircraft.

This flash codeword traffic is also noted on the Russian ELF and VLF networks
