Re: DRM (Digital Radio Mondiale) :: CHINA xHE-AAC codec DRM -
XYZ Jul 01 (Wed), 2020 05:23 UTC No.4593 [xHE-AAC] ** Extended High-Efficiency AAC audio codec
Recently, a new type of DRM broadcast has been sent from China. The codec called "xHE-AAC"
is used for that, and demodulation is difficult unless special software is used.
The new type of DRM broadcast still seems to be testing, playing nonstop Chinese music.
And the frequency is changed according to time. (Irregular)
12020kHz → 15630kHz → 15625kHz → 13775kHz → 17660kHz (All ID: 3F9)
** Thanks to Japanese DXer Hirabayasi !

New DRM software is required to demodulate this broadcast.
** Reference : https://www.reddit.com/r/RTLSDR/comments/grp6m2/dream_v221_for_windows_with_xheaac_support/
It still has a fatal bug, but it can be demodulated.
