and 11695 kHz (Hainan, 30 kW, to East China),
relaying domestic 5th program (Voice of China).

On October 18, 2018, the Central People's Broadcasting Station launched the
DRM short-wave digital broadcasting frequency registered with the HFCC.

>From October 18th to 21st, 2018, Beijing time will test the signal from

It is worth mentioning that, in late August or early September 2018,
11695 kHz registration information in the HFCC has been adjusted.

The 11695 kHz launch site was adjusted from Heilongjiang Qiqihar (QIQ) to
Hainan island Dongfang (DOF) in southern China, and the power was reduced
from 150 kW to 30 kW. The azimuth is adjusted from 220° to 41°.

In the recently published registration information of HFCC B18, the 6030 kHz
power transmitted by Beijing has been reduced from 100 kW to 30 kW, which
may be used for testing DRM for a long time...

At present, CNR uses three frequency tests to transmit DRM signals.
The parameters disclosed are as follows (Beijing time, UT +8 hrs):

 6030 kHz 0425-0205 (not Tuesday 1400-1700) BEI Power=30 kW Azimuth=0degr
11695 kHz 0900-1700 DOF Power=30 kW Azimuth = 41degr
15580 kHz 0900-1700 DOF Power=30 kW Azimuth = 16degr

Among them, 6030 and 15580 kHz are mainly for launching in North China, and
11695 kHz is mainly for launching in East China and South China.
