There’s a story over on The SWLing Post about recent attempts by the Chinese to purposely jam the broadcasts of other national services such as Britain’s BBC.
The jamming service is known amongst shortwave listeners as Firedrake. Using Firedrake, the Chinese government transmits music on top of broadcasts they wish to block.
The SWLing Post even has a 27 minute recording of Firedrake on 6,970 kHz, starting around 11:00 UTC, Saturday January 26, 2013. What is even more interesting is the subsequent denial of service attacks which ensued on the SWLing Post, from internet addresses originating inside China. This is certainly state-sponsored sabotage.
Reuters has even written on the topic: BBC says radio broadcasts being jammed in China
“The BBC strongly condemns this action which is designed to disrupt audiences’ free access to news and information,” the BBC said in a statement.
China is listed at number 173 out of 179 countries on the World Press Freedom Index compiled by campaign group Reporters Without Borders.
