All voice frequencies mentioned on this page are on the upper sideband.
    The aircraft callsigns are made of 5 digits.
    The primary/secondary designations reflect the usage by aircraft; the ground stations usually transmit on all frequencies simultaneously.

This network is associated with the Tu-95 strategic bombers and the Il-78 tankers supporting them. It is also known as the Bear net, after the NATO reporting name for the Tu-95, Bear.

The frequencies and the callsigns used depend on the season. The activity takes place mainly on the 8 MHz channels. During activity on this network, a single letter ("W" for Europe, or "G" for the Pacific) is repeatedly transmitted on one of the Morse ground frequencies around H+00, H+20, and H+40 for 2 minutes each.

Training operations are conducted away from the main frequencies. Voice communications take place within the 5.6 MHz range, with a single ground station present using a distinct callsign. Otherwise, the procedures used are exactly the same. The voiced callsigns for the ground stations when conducting training are named above as Moscow-2 and Saratov-2.
