Via ΣSDR / Sigma SDR (KiwiSDR). 6400 kHz 6.400 MHz PBS Pyongyang Pyongyang BS Pyongyang Broadcasting Station North Korea DPRK, hearing YL announcer in Korean and martial music at 2236 UTC. Weak signal but music is there. Signal improving.
I was hearing a Spanish language QSO on this frequency in USB mode (logged in the Peskies forum)...but the SSB voices are gone from 6400 kHz, leaving only the DPRK signal....as I type this the signal is fading down into nearly the noise making it almost unreadable. Carrier is there and there's bits and pieces of music coming through at 2237 UTC. SDR located on the CT/MA border.
