YHWH creepy interval music heard for only a minute, then either faded or gone. If you've heard their IS before then you know what I'm talking about. Unforgettable.
Update: I had the SDR recording during Borderhunter. I went back to 1738z and found YHWH there with very faint religious talk. So the station had been on for a little bit when I noticed the interval signal mentioned above.
