The Russian Ministry of Foreign Affairs maintains point-to-point HF radio links with dozens of its diplomatic missions throughout Europe, Africa, and Asia. Although those links no longer carry messages from Moscow itself, the missions still send upstream traffic over them.
This information is applicable to all links, regardless of the mode.
- Message Format: Description of the header format used on the Russian diplomatic/intelligence links.
- Link IDs: Numeric IDs for the Russian diplomatic missions, used in place of geographic names.
The communication modes used on this network are proprietary, and contain unique MFSK and OFDM waveforms.
- "Perelivt": Used on most point-to-point links since the mid 2010s.
- Serdolik: Used on most point-to-point links from the early 2000s until the mid 2010s, still the primary mode for a few embassies, and a backup mode for others.
- Mazielka: Selective calling system used by Moscow, associated with the above modes.
- RTTY: Used on most point-to-point links from the mid 1980s until the early 2000s, still used on occasional training sessions.
