A US hobbyist noted “jamming” of DW’s signal on 11645 kHz on 14 and 15 November, and to DW’s Amharic broadcast on 15640 kHz on 15 November. (Glenn Hauser, DX Listening Digest, 15 November)
A German listener said the interference resembled a combination of sounds, “like bubble, motorboat, pips, and whistle buoy howl”.
In a separate report, Ethiopian Review website reported on 13 November that VOA broadcasts to Ethiopia had been jammed since 12 November “with the help of the Chinese government that provided technicians and powerful radio jamming equipment”.
