That equipment is capable of 150 kW mean power with 9 dB crest factor. HFCC shows they are targeting Europe on that frequency at that time.

National coverage using DRM

Interesting discussion of Nationwide broadcasting using DRM. Many European countries could easily shift to DRM for their broadcasting needs now that the CML DRM1000 chip is available for receivers. In North America, national broadcasting services such as NPR could shift to DRM for signal delivery - if only DRM was permitted on AM/MW and FM.

Radio Free Asia tests DRM to China

 

@MohanNataraja16 on Twitter (X) received Radio Free Asia (RFA) DRM test broadcast in Mandarin on 11700 khz in London, UK on June 11, 2024 at 2100 UTC.

No further information is known about the test and it is unknown from where it was broadcast. RFA is operated by the US government and "...provide(s) independent, uncensored and accurate local news to a weekly audience of nearly 60 million who lack access to a free press or live in media environments vulnerable to authoritarian disinformation."

@atake on Twitter (X) has also confirmed this broadcast received in Nagoya, Japan.

Based on KiwiSDR reception, it is likely originating from Kuwait. Before sign-on Arabic music was being played as well.

@alokeshgupta says RFA DRM tests towards China are scheduled from 11 to 16 June 2024 at 2100-2200 UTC on 11700 kHz. Reception reports to qsl@rfa.org
