Seems like, the “mysterious” North Korean DRM network (MW+SW) carries the “Third Program” in encrypted DRM mode. I attached the opening of KCBS 3 with the schedule (airtime is 05:00-23:00!), and the DRMDEC window. It shows that EVS likely encrypted audio data is in the stream! The local KST time is also carried btw. The DRM network is on air from ~0440 – 2300 KST. The Third Network having the SAME airtime! So my hypothesis is the following: The DRM network feeds the local distribution points of the wired “Third Network” and also where no wire network is available: modified DRM receiver for this station, so the “wireless wired network”!
Third Network stream is here: https://koryofront.org/radio (labelled as KCBS-2)
