The monitored HF transmissions are distinct from the VLF role generally associated with the Goliaf transmitter. The exact technical relationship between the HF equipment used by NTFZh and the VLF transmitter infrastructure at the facility is unknown.

The NTFZh station has been observed transmitting on a variety of frequencies depending on propagation conditions and operational requirements. Its primary monitored frequency during the period documented in 2026 was 4844 kHz. (6916 kHz at daytime and 4617 kHz on nighttime since the 16/09/2026 Russian Military districts rebuild)
