"The T Marker" is a Russian military commandment network. It broadcasts on 4182 kHz around the clock. It is mostly noticeable by its channel marker sending intermittent tone dashes, like the Morse code character "T". Multilateration attempts seem to point towards the Tver area, which would imply that it is part of the Western Military District.

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).
