View source for Russian T600 Frequencies and Callsigns

The [https://www.sigidwiki.com/wiki/CIS-36-50 T600] list so far, compiled from udxf members and other sources, with my thanks;

==Technical and Tuning Notes==
Callsigns listed were either copied via fsk-cw opchat, ITU monitoring, or interpolated from tdoa/df fix.
There are many logs reported as T600 suspects that weren't id'd as T600 left out as they were many, but might create a pervasive list later on.
Some of the logs ending in 0.5 or other may have been mistuned by the logger but unsure, the listed are presumed cf so tune 2kc lower in usb mode to copy at 2kc in the decoder. A 360Hz filter centered on 2kHz with a notch right at 2kHz does wonders for copy. Any further logs, even if dated, much appreciated!

The free software [http://www.signalshed.com/rivet/index.html Rivet] can read this mode. It has its own [https://github.com/IanWraith/Rivet/wiki/Introduction wiki]

==Frequency List==
The [[Media:Russian T600 frequencies.zip|T600 Frequencies list]] contains over 400 T600 frequencies. Winzip or compatible is needed to uncompress it


==Contributors==
This list made possible by the logs of Wolfgang, Antonio, MCO, Thomas, and many other udxf contributors, as well as other online sources.
Included are frequency (all cf), call (if known), location (usually from hfdf), and other notes relevant to the pursuit of T-600 reception.
Dupes and obvious bfo offset error was adjusted where possible. All are CIS Navy save where noted.
