The letters and numbers are synthesized, possibly using two different voices. Notice the pronunciation of "declination", typical text to speech issue. The same station was heard on 10 MHz also.
My guess is a fake, and a poor one at that, at least the format could be more consistent. Also notice that all frequencies seen so far have been inside ham bands (both 30 and 20 meters). Although now that I posted that I bet we see some a bit outside the bands.
Of course I thought the same thing about EV01 when we first saw it, so maybe not.
T!
