Voice of Korea: Kim Jong-il

December 20, 2011 in hf | No comments

Kim Jong-ilOne of the great things about HF/shortwave monitoring is the fact we can listen to various stations from around the world. While many broadcasters have moved on to Internet streaming, there are still interesting stations to be heard. One of them is the Voice of Korea which broadcasts from Pyongyang, North Korea. The Voice of Korea gives outsiders a good opportunity to experience genuine broadcasts directly from the DPRK. With the passing of Kim Jong-il, I figured this would be an interesting time to tune in and was certainly not disappointed.

Here is a recording from the 12/21/11 VOK news segment on 13650.

The North Korea Tech has an excellent recording from the Voice of Korea broadcast where Kim Jong-il’s passing is announced over the air.

On Nov 7, 2011 the USCG Communications Station Kodiak received a call from the 150-foot Seattle-based fishing vessel Wizard regarding a 28 year old crew member that had collapsed and was showing signs of dehydration and shock. A Coast Guard MH-60 Jayhawk helicopter operating in the area was able to medevac the man from the boat and transport him to emergency medical personnel in Cold Bay. The Wizard is one of the crab fishing vessels featured on the hit show Deadliest Catch and is captained by Keith Colburn.

The US Coast Guard Communications Station Kodiak released the audio recording from the distress call and can be listened to below.

Deepwater Horizon Oil Spill

June 15, 2010 in hf | No comments

While most of the communications remain on VHF, there have been a few reports of activity on HF as well. Several people have reported hearing phone patches and fishermen discussing the BP oil spill on 8650 USB.

Another frequency to keep plugged in is 5320 USB. This is used by the US Coast Guard and was quite active last night and this morning. Reception here in California wasn’t all that great, but I did manage to snag a little audio.
