Nice catch Atrain!
Here in New York, I mostly only am able to hear the Voice of Korea's French and Korean services on 15180 kHz in the mornings and that's it. Their South Korean counterpart, KBS World Radio is always blasting in at S9 +20 on 15575 kHz in the mornings.
I always try to hear their English broadcasts but all I ever am able to receive is a barely audible carrier at best.
