The waveform consists of a MFSK-68 modulation with a visible empty place in the center of the spectrum, from here the name "34+34": inside these two sets, the tones are 47Hz spaced. Each 1 second are sent 10Khz-wide PSK-8 9000Bd bursts (2 symbol element periods length) possibly acting as sync. Unlike normal MFSK (1 symbol = 1 tone) the signal use 5-tones symbols so that its manipulation speed sums to 47Bd (45 MFSK symbols + 2 PSK symbols). Very often,CIS-3000 PSK-8 bursts have been seen before MFSK-68 transmissions possibly acting as selcall feature, but it's a my guess. MFSK-68 is supposed to be used by Russian Intel/Diplo networks.
This is not theresult of a systematicmonitoring but just a grouping of my logs sorted (and keep updated) by frequency and times; so it doesn't claim to be complete or to provide a sort of schedule for such transmissions.
