Mazielka is a calling system used by the Russian Ministry of Foreign Affairs. It emits a string of 6 tones in succession, 333 ms long each, followed by a 1380 ms pause, repeated continuously. The standard emission mode is USB + carrier, and the tones are assigned the following frequencies, in hertz:

1 2 3 4 5 6
815 845 875 910 950 990

The purpose of the signal is merely to catch the remote operator's attention for a two-way contact using a mode like "Perelivt" or Serdolik.

There are at least 53 allocated tone sequences, each corresponding to a single Russian diplomatic mission. Each sequence has its own pool of frequencies, one of which is chosen for the broadcast. In case no response is heard from the diplomatic mission, Mazielka calls may be broadcast on several frequencies in succession.

The Mazielka tone generator is sometimes used to emit test strings like 123456, 111666, 121212, or 111111. In one particular case, the sequence 111666 can be heard about an hour before European E07, M12XPA, and XPA2 schedules, on the frequencies these schedules are going to use, in ascending order (regardless of the order used on the schedule). It is unknown to what degree Mazielka is related to the Russian 7 operator.
