This winter, in an earlier post, we picked up on a piece by Martyn Williams alleging that North Korea was experiencing sporadic failures in its jamming of foreign radio broadcasts and even having difficulty keeping its own foreign radio service on the air. It was speculated that these difficulties were related to the seasonal pattern of electricity supply and demand which generates shortages in the winter. Well, spring is here, power demand has slackened, hydroelectricity production is back up, and the BBC is reporting that North Korea is jamming the GPS systems of airliners flying in and out of South Korea's Incheon airport. According to a South Korean government official, the problems since Saturday have affected 250 flights involving 18 airlines. But not to worry, according to a South Korean Transportation ministry official, "no serious threat to the safety of flights because planes are using other navigation devices." Well, that's a relief.
Personally, I'd rather leave my jammin' to the universally loved Bob Marley...
