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!
