This station has been active for the last few months.  Frequencies used to date, that I know of, are 10400, 11000, 13400, and 16000 kHz.  Modes used have been both AM and USB.  Times have been varied but the station may be most active between 1400 and 1600 UTC.

The message sent is always (every time that I know of) the same and starts with GR35 N0125.

The station appears to be best heard in Europe, with reporting stations in France and Austria appearing to have the strongest signal.  Direction of arrival with relationship to southern France may indicate a source roughly in the direction of Romania/Bulgaria/Turkey.

The music, either before or after, has been reported a few times, but is not heard most of the time.  There is some discussion on this music, it seems odd that it is not present most of the time if it is really a part of the signal.

Because of the stations actions there is a school of thought that this is not real, possible it is a spoof or fake.  The oddities that simply do not fit with numbers stations are: the same message for months on end, music at times and not at others, inconsistent start times, odd start times, frequencies and times that change seemingly at random, etc, etc.
