UNID DPRK(?) "Dream Test" logged for 82 minutes from 0921-1043 UTC.Max. 14,46 dB SNR and 11,93% decoded audio. It looks like they're using the Dream TX. I was listening and I noticed that they used 4.5 kHz BW. They used 400 ms interleaver which has never been any good for the decoding. In the beginning the signal strength was poor but later the SNR improved. The audio bandwiidth was only about 3000 Hz and when there was no music, a loud background hum could be heard. The language was Korean.
