North Korea appears to be testing digital radio broadcasting.<\/p>\n

Hiroshi Inoue, a radio monitor in Japan, received on Wednesday the country\u2019s international radio service, Voice of Korea, broadcasting on shortwave using DRM (Digital Radio Mondiale). DRM is a digital broadcasting technology developed for use on AM and shortwave services.<\/p>\n

[…]The broadcasts are taking place on 3,560MHz, a frequency used by the Voice of Korea in the past for conventional analog shortwave broadcasts.<\/p>\n

[…]North Korea\u2019s testing of DRM comes at a time when the country appears to be upgrading its international radio broadcasting system.<\/p>\n

In mid-June 2011 the country\u2019s Ministry of Posts and Telecommunications\u00a0signed a deal<\/a>\u00a0with Beijing-based BBEF Tech for several new\u00a0radio and television transmitters. The Chinese company trained North Korean engineers in how to install them.<\/p>\n

At least one of those transmitters now appears to be on the air. North Korea\u2019s transmissions on 11,680kHz shortwave are now broadcast spot-on that frequency. In the past they drifted a little either side of the correct channel.\u00a0(Thanks to\u00a0DX Aktuell<\/a>\u00a0for the tip!)<\/p><\/blockquote>\n

\"\"<\/a>DRMNAinfo<\/a>\u00a0comments:<\/p>\n

Here are some cool videos of the English language\u00a0June 7th broadcast<\/a>\u00a0and the\u00a0June 8th broadcast<\/a>\u00a0in Korean. As you will hear, the high production values, overly aggressive compression and sibilant laden distortion present in VOK analogue broadcasts translate well to the digital medium of DRM. Now all we have to do is convince\u00a0Kim Jong-un\u00a0<\/a>to aim the antennas our way for some NA reception opportunities!<\/p>\n

Additional info\u00a0here<\/a>.<\/p><\/blockquote>\n

I would like to thank\u00a0Kim Elliott<\/a> for the news tip on North Korea.<\/p>\n

Note that this will be a difficult broadcast to hear and decode in North America, but many regions within Asia will be within the broadcast footprint.<\/p>\n","protected":false},"excerpt":{"rendered":"
