I'm listening to them now, on 3.140 and various other frequencies in that region. I don't speak any Russian but they sound the same as the CB operators you hear from Russia on 27 mhz. I wonder if they're pirates using old ex-military gear? That would explain some of the unstable signals. It reminds me of the amateur radio signals you'd hear back in the soviet era, when the hams over there built their own "rough and ready" transmitters, mainly due to lack of access to fancy Japanese "black boxes".

There are many stations working in AM in the band 3000-3210 Khz. The
carriers are not too stable. On some frequencies there are several stations
with simultaneous trafic, so I presume they are far from each other.
Language seems russian, not sure, and trafic is professionnal, rather
strange for AM transmissions.
Does someone knows what service it is?

Here is some audio samples received in France:
