Welcome to the CIS Modes article. This table will list the various digital modes used by the Russians (a.k.a Commonwealth of Independent States) and their member states. While software like Rivet and Sorcerer will decode some of these modes, the traffic is usually heavily encrypted. Deciphering the meaning of this traffic and stations is very much an ongoing process.

This list is very far from complete - Antonio I5-56578's blog and Priyom are two sites that you should visit if you're interested in this phase of DXing. Both of these sites, along with the links for Rivet and Sorcerer, can be found in our HF Appendix

The CIS Mode Waterfalls page has all of these waterfalls (in thumbnail form) for easy reference

Sporadic CIS modes

Who knows if these will ever return? Included in this list are ones that were rarely noted active, or have since vanished. Possibly this is due to testing a modem or a new path between stations - we may never know. 'Last seen' refers to the last time this mode appeared in the UDXF logs.
