S6 2349z with RTTY over the top. RTTY sounding like someone bumped the vfo?? Constant interval beep too.
The background RTTY seems to be on some type of loop. When it starts and ends, the sound is unique...
I have heard some weird stuff on HF, but this is near the top of the list.
0010z numbers seem to have stopped. beeping and rtty continue.
0014z just the beeps, and those just stopped
