It is a short message for giving trustworthy analysis results. But it doesn't seem too "random". And there are only 19 out of the 26 letters of the Latin alphabet.

The same station reappeared on 10400 kHz, between roughly 1400z - 1600z with the same message, and occasionally classical music . Also, I heard some OM talking (not sure for the language). Unfortunately I don't have any sound samples.

To be honest, I think this is a hoax. But I'll give it a try whenever I have free time, just for the fun of it!

UNID station on 11000 kHz

A UNID transmission began at 1429z on 11000 kHz, USB mode. Moderate signal strength with some QSB. Note the noisy background and the funny sounds near the beginning and the distinct pronunciation of the letter v. It faded out at 1503z.
