North Korea is testing digital shortwave broadcasting via DRM

As Vatican Radio pulls out of DRM, North Korea moves in. What a strange and shifting international broadcasting landscape:

North Korea appears to be testing digital radio broadcasting.

Hiroshi Inoue, a radio monitor in Japan, received on Wednesday the country’s 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.

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

[…]North Korea’s testing of DRM comes at a time when the country appears to be upgrading its international radio broadcasting system.

In mid-June 2011 the country’s Ministry of Posts and Telecommunications signed a deal with Beijing-based BBEF Tech for several new radio and television transmitters. The Chinese company trained North Korean engineers in how to install them.

At least one of those transmitters now appears to be on the air. North Korea’s 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. (Thanks to DX Aktuell for the tip!)

DRMNAinfo comments:

Here are some cool videos of the English language June 7th broadcast and the June 8th broadcast in 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 Kim Jong-un to aim the antennas our way for some NA reception opportunities!

I would like to thank Kim Elliott for the news tip on North Korea.

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.

CDNSE Newstar DR111 First Review

Based on this initial review, it appears that the CDNSE Newstar DR111 is an improvement over the company’s last portable DRM radio, the DiWave.

[T]he unit is quite sensitive. RNZI evenings at 17675kHz and 13730kHz can be received various places within my house with only the internal whip. REE at 9630kHz using an external ham vertical antenna was similar copy on Pappradio (with a slight edge given to the Pappradio.)

DRM Audio while adequate, seems narrow and compressed in comparison to DReaM on my PC. I verified this by switching A to B between the Newstar and the Pappradio with DReaM using my JBL headphones. I’m beginning to wonder if the DRM audio is being processed by the DSP, just like the analogue audio. The DSP in analogue is a tad too aggressive. A real bonus in analogue is the adjustable bandwidth (1-6kHz) however. That and the DSP make analogue quite enjoyable even in the crowded 49M (6MHz) band. I have been listening to BBC on 5875kHz in the early AM with armchair copy and great audio using only the whip (throughout the house).

Voice of Nigeria broadcasts DRM from their new facility

(Source: VON via Kim Elliott)

VON’s ultra modern transmission station launched 
Lawan Hamidu, Abuja

President Goodluck Jonathan has commissioned Voice of Nigeria’s (VON) ultramodern super transmitting station and its revolving antenna, located at Lugbe, Airport Road, Abuja.

President Goodluck Jonathan, represented by the Vice President, Namadi Sambo at the event, stated that the project was in line with Federal Government’s commitment to meet the 2015 global deadline for the digitization of the broadcast industry and international best practices.

Sambo said “We are today empowering the Voice of Nigeria to robustly project our international profile and make Nigeria heard positively and more widely around the world,” adding that “the transmitting station we are commissioning today is therefore aimed at making VON better able to meet its vital obligation of telling our story from our own perspective.”

The President noted that VON established in 1961, as an external arm of the then Nigeria Broadcasting Corporation, was in recognition of the critical role the country was playing in freeing other African countries from the shackles of colonialism.

“Nigeria understood in her early history that it needed an external voice to reach the world as the leader of Africa and to provide a platform for rallying African voices,” he stated.

President Jonathan, charged the management and staff of VON to as a matter of priority develop programmes that would make the Radio station the choice of listeners in and outside the shores of Nigeria.

He added that “You have the duty of helping to inculcate in all Nigerians abiding peace and pride in Nigeria and the knowledge that we all have a stake in ensuring that our strive towards sustained economic growth and development is not compromised by breaches of peace and security in any part of the country.”

Similarly, Dr. Jonathan assured that Government was committed to meeting its obligations to VON and other broadcast organisations.

“In keeping with my avid policy of expanding the political space and driving the ideals of democratic process, this administration is not interested in turning VON, or any government broadcast organisation into an uncritical mouthpiece for our policies,” he emphasised.

In his remarks, the Minister of Information, Mr Labaran Maku, called on President Jonathan to ensure the immediate completion of the second phase of the VON project.

He also appealed for additional funds for the nation’s information sector for the smooth execution of government transformation agenda.

The Minister said “Mr President what we now need is the second phase of this project, that second phase would mean the construction of two more transmitters and we don’t have those two transmitters we are going to have a heavy burden on the existing transmitters and this will not be good for this technology. So, we plead with Mr President that after this commissioning we will want Mr President to approve the immediate execution of the second phase of this project. The Information sector is need of infusion of funds to make us give Nigerians and Africans all over the world the best programmes.”

In his welcome address, the Director-General of VON, Abubakar Jijiwa, expressed optimism that the second phase of the project, when completed, would enable VON to embark on 24-hour broadcasting.

Alhaji Jijiwa solicited for Presidential intervention for the VON expansion projects which included the construction of two additional transmitters and antenna systems in line with global best practices and standards, construction of VON Abuja Broadcasting House as well as rehabilitation and upgrading of the ageing Ikorodu Transmitting Station.

Mal. Jijjiwa stated that “The second phase of this project needs be commenced urgently. It will comprise of two additional super power transmitters and one fixed and one rotatable antenna. When this is done and completed, VON would have the capacity for 24-hour broadcast and we can move this from our existing 18-hour broadcast and this would be the hall marks of simultaneous broadcasting which every external broadcaster hopes to achieve.”

The event included, the commissioning of three Super-Power Transmitters, three fixed and one rotatable antenna, the first in Africa and sixth in the World.

Voice of Nigeria, Nigeria’s external broadcast station is mandated to project Nigeria and Africa’s views to the world.

Located in Lugbe, a suburb of Abuja in the Federal Capital Territory, the transmitter has a rotating antenna, with the capacity of a hundred and fifty kilowatts and is powered by one thousand two hundred high tension generators.

New Digital Studio

On Monday, the Voice of Nigeria commissioned an ultra-modern digital studio in Abuja, as part of efforts to enhance its broadcast.

The new studio, commissioned by the Minister of Information, Mr Labaran Maku, is named after Mrs Stella Bassey, a seasoned broadcaster and former Deputy Director, Programmes of the Voice of Nigeria.

Commending Voice of Nigeria for its quality broadcasting, Mr Maku urged the radio station not to relent in its efforts to maintain world class broadcast standards.

The Director General of Voice of Nigeria, Mallam Abubakar Jijiwa said the station had a culture of rewarding hard work.

Mallam Jijiwa said the studio was named after Stella Bassey because of her immense contributions to the corporation and the country in the area of broadcasting.

Could the DR111 DRM Radio be the portable we’ve been waiting for?

One of the reasons DRM (Digital Radio Mondial) has struggled to gain global popularity is that there has yet to be a portable radio solution with universal appeal.

Perhaps the future Chengdu NewStar Electronics DR111 DRM Radio will change that? According to their website, the company is certainly setting out to make an affordable receiver that is simple to operate. Hopefully, CDNSE has learned from this radio’s predecessor; ergonomics, affordability and overall ability to receive and decode DRM signals are the keys to its success.

We have added the DR111 to our Shortwave Radio Index. Check back as we will post updates.

Radio World looks into the future of digital shortwave radio

(Source: Radio World Online)

“DRM is not seen as a profitable line for the major manufacturers,” said Sennitt. “A few smaller manufacturers have produced DRM receivers, but the unit cost is still too high, and there simply aren’t enough DRM transmissions audible at any one location to stimulate consumer demand. It’s a classic chicken and egg situation — which comes first, the transmissions or the receivers? The broadcasters and the receiver manufacturers are each waiting for the other to move first.”

DRM: First Transmission for Southern Africa

(Source: DRM Consortium Press Release)

The DRM Consortium will make its first ever DRM transmissions for Southern Africa in French and English on October 11th on the occasion of the Digital Radio Conference organised by the European Broadcasting Union (EBU) at the headquarters of the European Parliament in Brussels.

The two day conference will include two live studio discussions on the possibilities and future of digital radio from the multimedia radio studio of the European Parliament. The programmes aim to showcase multiplatform and distribution techniques in front of a studio audience of Digital Radio Conference delegates.

The live show in French from 1200-1300 GMT will be followed two hours later (1400-1500 GMT) by a Digital Radio Show in English with international participation including the chairpersons of the DRM and WorldDMB Consortia.

Both the French and English programmes will be carried live on DRM SW 21800 from Ascension Island in the Atlantic Ocean and should be heard in countries like South Africa, Angola, Zambia, Lesotho, Namibia, Zimbabwe, Botswana, Mozambique. The English programme will also be carried at 1800 GMT into Southern Asia on DRM SW 12085, at the end of the daily regular BBC/DW transmission.

Ruxandra Obreja, DRM Chairperson, says: “This is an exciting and imaginative undertaking that will demonstrate practically, even if for a short while, to European MPs and radio enthusiasts at thousands of kilometres apart the capacity of DRM to cover huge areas with excellent audio quality programmes. We are grateful to the EBU for the opportunity to showcase, alongside other platforms, that part of DRM, the only standard for all bands below and above 30 MHz, that could offer so much to the radio lovers in Africa.”
