Thanks for the alert - I had to get on the KPH SDR to hear it, but it was there when you posted this yesterday and it's there again today. This morning for a while I was getting QRM from either CRI in Thai or CNR8 in Korean (I couldn't hear it well enough to determine which language it might be), but that disappeared into the background.
This is on their website, it's just confusing because they list it by Korean time with UTC underneath. But I do see it on this chart, as well as hearing definite KBS World ID's in English with English commentary on the K-pop music being played.
