|Active stations||E17z, S06s|
This operator is unidentified and of uncertain origin. It runs E17z and S06s, which seem to have obvious origins in the Russian E17, E06 and S06 stations. However their formats are slightly different, E17z and and S06s featuring pauses between the five 0 of the outro. With time they also received different voices.
Painfully compelling divergences reside not in the format itself, but in the contents: this operator uses very short messages, usually only between 5 and 8 groups. They are not encrypted using one-time pads, but more probably use a codebook, as pieces of identical group sequences are often observed multiple times in different transmissions. This operator also follows clearly different scheduling habits. Thus, and despite some habitual confusion from reporters, S06s operations really have nothing to do with S06.
Known test frequencies are 8180 and 10240 kHz, for E17z, using ID 274.
