Tuned through the 25 meter band, heard the data pulses again, on top of a carrier.
This time they were on 11930 khz, and I could just barely hear some audio way in back of them, sounded like a woman, and the pace and tone was non-English, poss. Asian -- but because the audio was unreadable, I'm just making a complete guess here, from the tones of the voice.
I'm wondering if this isn't some sort of jammer.
Were still on the frequency during recheck at 0641z, audio was a tiny bit stronger behind the pulses, still unreadable.
Looking at the SW schedules, nothing is usually scheduled here in this time slot that would be jammable. The only thing I can find scheduled is R. Belarus.
The data pulses didn't really sound like LINK-11, as I noted in my previous post on this sound. Unless there's an 'idle' LINK sound, like when RTTY is sort of idling, it just puts out blips.... but I don't know enough about sounds to venture a guess.
