This is a Russian military commandment network serving the Western Military District, mostly noticeable by its channel marker sending intermittent tone dashes (like the Morse code character "T"). Over the years, only very rare messages and test counts have been heard on it. The messages were of the "Monolith" format and used the callsign Osnova-48 (Russian: Основа-48).
