Mystery Asian DRM signal on 927 kHz

UPDATE 202301127: @fractional_n posts - "Probably North Korea.

The North Korean station at 6140kHz also had an ID=64."


From @fractional_n (located near Tokyo) on Twitter:

(Machine translated from Japanese) "From last night's medium wave record

I discovered that DRM waves are being emitted at 927kHz!

Although NHK Kofu Daiichi is strong, the SNR increases to a maximum of 8 dB. ID=64 and no station name label is displayed. However, the contents of the data cannot be demodulated. It seems that the data format cannot be decoded by Dream.

It is speculated that it probably originates from China or North Korea."

Any ideas?
