For you listening pleasure: thirty minutes of NHK Radio Japan’s English language service.

This broadcast was recorded an hour ago, at 10:00 UTC on 9,625 (April 19, 2013).  Though NHK has dropped their English language services into North America, you can still receive their broadcasts targeting other regions quite easily.

Pirate Radio Recordings: Hardtack Radio

For your listening pleasure: a 24 minute recording of the pirate radio station, Hardtack Radio.

Hard Tack Radio plays US Civil War era songs “celebrating the Blue and the Gray.”

I caught Hardtack’s broadcast Friday night (April 12) around 23:10 UTC. Their upper side band signal was pretty strong and well above the active noise floor, though there was a heterodyne/data noise located right around 6926.8 kHz. You won’t hear this noise in the recording below, because I effectively used the WinRadio Excalibur’s notch filter to eliminate it. At the very end of the recording, I turn off the notch and you’ll hear the noise a few seconds before the broadcast ends.

Propaganda from the source: Listening to the Voice of Korea on shortwave radio

FlagNorthKoreaOne of the countries dominating the headlines of global news lately is North Korea. As Kim Jong-un raises tensions and rattles his nuclear saber, the rest of the world is attempting to determine if this is a egotistical show of power for the benefit of all observers (as with previous leaders) or if there is real intention behind the rhetoric.

Just this morning Pyongyang has warned that Tokyo would be a primary strike target if war were to break out, or if their test missile is downed; they’ve even moved their missile launch pad into position.

Regardless of outcome of these provocations, I know that the bulk of the North Korean population will suffer. North Korean mainstream “news” consists of images of military parades in the immaculate capital city of Pyongyang; but the reality is that most of the population live in rural North Korea, which is subject to severe food shortages and extreme poverty.

We know North Korea is a country that carefully controls and manipulates their media internally; they also broadcast the same flavor of propaganda externally on shortwave radio via the Voice of Korea.

As shortwave radio listeners, we have the distinct advantage of being able to listen directly to the case of North Korea. We can actually hear (and analyze for ourselves) the North Korea propaganda directly from the source. Note that it’s not uncommon for the Voice of Korea to unexpectedly go off air, likely due to power shortages: this fact is much more suggestive of the of general conditions in the country than the “news” itself.

Depending on where you live in the world, your ability to hear the (relatively weak) Voice of Korea will vary.  If you live in the Asia/Pacific region, the station is very audible.

Yesterday morning at 10:00 UTC, I recorded an hour of their English broadcast to South America on 11.71 MHz. You can download an mp3 of the recording by clicking here, or simply listen via the embedded player below:

Shortwave Radio Recordings: Voice Of Islamic Republic of Iran

Tehran, Iran

Tehran, Iran

On Thursday, March 14th, I tuned to the Voice of the Islamic Republic of Iran on 9.895 MHz at 02:30 UTC.

The signal was strong, but audio somewhat typically over-modulated. However, I was able to record the full broadcast.

Shortwave Radio Recordings: VOA Special English

VOApodcastimageSPecialEnglishI believe that VOA Special English may be one of the best educational resources on the shortwaves. At Ears To Our World, we find that it is often the most popular program in countries where English may be the official language, but where locals only speak it as a second language.

Over four years ago, I mentioned a Special English broadcast honoring Henry Loomis, the creator and champion of Special English at the VOA. Click here to read the archived post.

I recorded this particular broadcast of VOA Special English on March 19, 2013 at 1:30 UTC on 5,960 kHz.

Shortwave Radio Recordings: Radio New Zealand International

One of my favorite shortwave radio broadcasters is Radio New Zealand International. RNZI has authoritative news–with a focus on NZ and the Pacific islands–music, sports and their own unique character, though they operate on a very modest budget by international broadcasting standards.

The RNZI interval signal is charming and unmistakable: the call of the New Zealand Bellbird.

Fortunately, in the 3 hour recording of RNZI below, I caught not only the interval signal as the broadcast began, but also as it went off the air. This recording was made on March 14th 2013 starting around 8:00 UTC on 9,765 kHz. (You’ll note news of the Pope.)
