Lots of DRM activity going on in China!
It was reported via a Japanese listener on WOR that on 29 October 2024 an emergency broadcast test occurred on 17700 kHz in DRM mode, broadcasting weather in Sichuan Province.

B24 DRM schedule of CNR release 8 November 2024:
Beijing 13825 kHz 0100-0900 30kW 175deg.
Dongfang 17770 kHz 0100-0900 30kW 16deg ID:27FA
Kunming 15180 kHz 0100-0400 0800-1100 30kW 32deg ID:3EB
17800 kHz 0400-0800 30kW 32deg ID:3EB
Urumuqi 9655 kHz 2200-0100 0800-1200 30kW 98deg ID:3FC
17830 kHz 0100-0800 30kW 98deg ID:3FC
Additional frequencies registered in HFCC B24 but not officially announced
Beijing 6030 kHz
Dongfang 11695 kHz (and possibly 21530 kHz)
Qiqhar 11990 kHz
13710 kHz
13850 kHz
It is thought that the Qiqhar transmitter has been converted to jamming. Also 21530 kHz (30kW 341deg Dongfang), which was registered as an irregular frequency in A24, is reported to have been still used in B24.

Another set of frequencies using the CUC-ECDAV ID (corresponding to the Research Center for Radio-Television Digitization Engineering of the University of Communications of China) have been spotted on:
6185 kHz
7500 kHz
9500 kHz
11500 kHz
Lastly, on 2 November 2024 the ID DRM broadcast from Fuzhou was seen.

With all these frequencies and activity, we can hope that the great propagation conditions result in North American decoding for many of these signals!
