The usual caveats apply when it comes to news from North Korea due to the inability to confirm the rumors that come out of the place. With that said I can definitely imagine this execution happening considering the importance of isolating the population from outside information:

Authorities in North Korea executed the owner of a fishing fleet in front of 100 boat captains and fisheries executives for secretly listening to broadcasts by Radio Free Asia and other forbidden media outlets while at sea, sources in the country told RFA.
The fishing boat captain, who picked up the habit of tuning in to broadcasts from abroad while in the military, confessed to having listened to the U.S. government-funded media outlet for more than 15 years, after he was turned in by a resentful crewman at his base in the northeastern port city of Chongjin.

You can read more at the link, but has anyone in the media bothered to ask President Moon what he thinks about executing people for listening to the radio?
