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:

I'm horrible at foreign languages but did you check this list of stations?

One other possibility is if you are certain it's Russian, could be a
harmonic of 1500-1600khz transmissions.

I get several strong signals on 90 meters here in the states at night
from US domestic shortwave broadcasters and some weaker spanish stations
from the topics.

Good luck.

Definitely Russian transmissions. Not regular broadcasters, though!
Does not sound like two amateurs either, it is not SSB.Strange
frequencies as well. Russian pirates,since it is out of band. Bandwith
is around 4KHz,can't be more-it sounds very distorted and difficult to
discern most words. One of them clearly complains about QRM and they
sound like technical guys to me (may be mil traffic as well).
Intermodulation from 40 meters, perhaps?

Harmonics or intermodulations are unlikely because of the long distance (if
they are in Russia) and probably I would have received them on their regular
frequencies.
They are operating every day for 5 days (I had never noticed them before but
possibly they were there) and are received here evening and night. I feel it
is not traffic such CB or amateur, but professional.

Thanks for the informations, and to Patrick too.

Here is a much better record:

Are they definitely double sideband AM and not SSB with a carrier?

To email me remove the letter vee.

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".
