First heard in 2017, this station serves the Western Military District of Russia and operates without a channel marker. While no message is being sent, often a carrier, or a 50Hz ground loop noise is present. It is the main channel in a network of three stations. All the messages sent on this network are proceeded by a 800Hz test tone (which often lasts upwards of 2 minutes) and one or more test counts. The test counts and test tones are sent sometimes up to half an hour before Monolyth transmissions, and there are several of them throughout that time.

The traffic consists of Monolyth messages and multiple daily test messages (usually 3-4 a day, sometimes more). Monolyth messages are transmitted simoutaneously on a voice and morse channel and have either one, two or sometimes three 4-digit number groups per codeword, which makes it different from other networks, which usually have two groups per codeword only. The morse channel often sends radiograms, network checks and Z-commands, which aren't transmitted in voice. Morse transmissions usually start with a series of the letter V repeated.

Radiograms transmitted via morse on this network are unique, as they contain two groups of three letters, each starting with the letter Z. They are included in the group count in the header of the message. Often the letters, out of which the radiograms are composed, are rarely seen in radiograms of other networks (for example: Ь, Й or Э).

On this station the Monolyth messages are read first in full without phonetical spelling, and then once again with spelling and with each digit read separately, as opposed to other stations which read them as whole numbers.

The test messages are addressed to either the collective callsign, or callsigns of single units. In January and February 2022, 14 recipients (besides the collective callsign) have been heard in messages.

The frequencies and callsigns (both of the sender and recipients) change throughout the year and are represented by the table below:

Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
Collective callsign Vermut-27 Fikus-30 Lotsman-94 Goboj-55 Vermut-27
Sender callsign, even days Galop-03 Styep-90 Sobol-21 Pila-95 Galop-03
Sender callsign, odd days Opora-25 Balans-55 Diktor-71 Kinzhal-25 Opora-25
Day frequency 4246kHz + 5256kHz 4213.5kHz + 4357.5kHz 4982kHz + 5163.5kHz 3564kHz + 4982kHz 4246kHz + 5256kHz
Night frequency 3346kHz 2371kHz + 2654kHz 2738kHz + 2829kHz 2382kHz + 3355kHz 3346kHz
Morse frequency 4256.5kHz 4060kHz 4213kHz 4224kHz 4256.5kHz

Very often, the message with the codeword "ВЕЖА 0505" can be heard on the network. The contents of the message do not change with the frequencies and callsigns - it remains the same throughout the year.
