China radios demand in North Korea
Smuggled miniature radios from China are meeting a demand in North Korea to hear what it is like in the outside world.
Authorities are reported to be cracking down on DVD copies of television dramas and movies especially those shown on South Korea TV.
However miniature radios are rapidly the way to hear the news and about culture from abroad. North Korean radios are locked to state-approved frequencies.
Anyone with a battery-powered Chinese radio can be arrested for espionage, but are cheap and easy to conceal.
