This station of the Russian military operates in morse and sends Monolith messages, primarily to the collective callsign XHOP. It is believed to be the most important station in the Russian Military, often initiating Monolith traffic on most known networks both in voice and morse.

When transmitting Monolith messages, more than 10 frequencies are used at a time in most ranges of the high frequency spectrum. Sometimes, a Monolith message for XHOP is repeated with the same contents on the REA4 channel (for the callsign A2CA). If the message gets repeated, there is a chance of it appearing on the Buzzer for the callsign NVTI (not always with the same contents), and many other voice and morse channels.

Most interestingly, the chain of messages initiated by a XHOP message spreads to the ground forces, air forces and navy channels of both the Western and Southern military districts of Russia.

The station seems to have a very strong connection to the network with the callsign 596E, with messages for XHOP being spotted on frequencies normally used by 596E for Monolith messages (10561kHz for example).

The table above represents frequencies, on which Monolith messages for the callsign XHOP were spotted. Not all frequencies are active when transmitting messages and their use varies between transmissions.
