Many thanks to SWLing Post reader, Mike R, for sharing this article from Asia Radio Today:

During a session on Public Service Broadcasting (PSB) at Radio Asia, Fayyaz Sheheryar the Director General of All India Radio said all PSB [Public Service] broadcasters are facing the question of how to make revenue within the public service model.

As governments are reducing funding for public service broadcasters, “there is competition between hedonism and altruism,” he said.

“If we want to earn money would it be at the expense of ethics? This is a question that requires everyone’s attention.”

The expansion of tv channels in India overshadowed radio for a while, but radio has come back to life “thanks to the deregulation of radio, new licences and new frequencies on FM and [DRM]” according to Sheheryar.

All India Radio has introduced new channels to compete with the new private commercial channels.

But, like other public broadcasters else where in the world, All India Radio is “facing questioning from commercial broadcasters about our role.”

[…]In India, All India Radio is allowed to take advertising, but advertising is not allowed to affect decisions on program content. It is heavily used by advertisers to reach both educated and mass rural populations, but the new private channels have taken a share of the pubic service broadcaster’s significant ad revenue.

“Public service broadcasting is a keystone of democracy,” said Sheheryar.

“Should we leave it to the market to decide the content of PSB? PSB gently leads the masses to more mature values and services all sectors of the population regardless of whether the have money to spend or not. Ratings cannot be the sole yardstick to measure the success of PSB.

[…]“The proliferation of private broadcasters has also contributed to the questioning of PSB’s role.”

[…]The question of how to fund AIR now that it is autonomous is constantly being discussed. All India Radio uses a “hybrid model of funding” with some government funding and some commercial revenue funding. Other sources of revenue are program sales, news media sales, facilities hire and transmission rental.

Despite the philosophical and revenue challenges Sheheryar is optimistic: “Public Service Broadcasting is on a revival course despite all the challenges. The [Indian] Prime Minister’s choice to broadcast regularly on AIR has helped us… For PBS to survive it must be recognised as a creative art and treated accordingly.”

Many thanks to SWLing Post reader, Bob La Rose, who shares a QSL he received (see above and below) from Radio Havana Cuba after they had only been on the air a few days back in 1961.

Amazing, Bob! Thanks for taking the time to scan and share this report!

Also, many thanks to Arnie Coro, Host of Dxers Unlimited at Radio Havana Cuba, for sharing the full text/script from his May 1st 2016 anniversary edition of DXers Unlimited:

Radio Havana Cuba
Dxers Unlimited
Dxers Unlimited’s weekend edition for 1 May 2016
By Arnie Coro
Radio amateur CO2KK

Hi amigos radioaficionados, welcome to the weekend edition of Dxers Unlimited, today l am happy to celebrate with you all the 55th Anniversary of Radio Havana Cuba… Yes amigos, it was on the first day of May of 1961, during the May Day celebrations when Cuba had just won the battle against the mercenary invasion that we went on the air using our present name Radio Havana Cuba… Two announcers, Orlando Castellanos and Fernando Alcorta announced to the world that Radio Havana Cuba, was on the air… Previously we had used the name Cuban Experimental Short Wave, but from May one of 1961, we are known worldwide as Radio Havana Cuba…

So today is a very special day… remembering those who have passed away after many years of valuable services to our station, like Pedro Costa the General Administration Manager, Carlos Estrada our Chief Engineer, and former Director Generals Marcos Behamaras. Orlando Fundora, Jose Antonio Caiñas and Alfredo Viñas. I also keep very nice memories of Angel Hernandez our bilingual announcer with the most effective voice for short wave radio that I can recall, and also I remember Manolo Ortega, reading our Spanish language editorials so that they could be heard clearly through his powerful voice…

Si amigos, I was there at the station 55 years ago as a young radio technician in charge of supervising the operations of our studios and transmitters that at that time included four Brown Boveri Swiss made short wave transmitters connected to a still under construction antennas farm, and the two studios borrowed from Radio Progreso until we could finish building our first studios .

The history of Radio Havana Cuba is full of very relevant moments, like the day that our Experimental Station announced to the world that the mercenary invasion that entered the Bay of Pigs had been defeated after sixty six hours of fierce combats .

With a lot of enthusiast and the impacting presence of a new generation of announcers, journalists , technicians, engineers and support personnel we are moving ahead to provide the best possible programming keeping our short wave transmitting facilities because we do believe on the use of international short wave broadcasting, while not disregarding the feeding of streaming audio to the Internet-

I am Arnie Coro, your host here at this special 55th Anniversary edition of Dxers Unlimited, that will continue in just a few seconds after a station ID..

Musical short cut

Yes amigos this is Radio Havana Cuba, using short wave frequencies at different times of the day on the 16, 19, 22, 25 ,31, 49 and 60 meters bands… and now our next radio hobby related item, a very popular section of this show under the name Antenna Topics , that is dedicated today , at the request of several listeners to a very effective Dxing antenna, low take off angle radiator, known as the HENTENNA, A great number of listeners from all around the world have written to me recently, asking to learn more about this Japanese antenna design , known as the HENTENNA, that seems to continue to be making headlines in radio publications around the world once again… But before telling you more about the mysterious HENTENNA…. A solar activity update… believe it or not, we are seen the solar flux moving up to very near 100 units for the first time in many weeks… following the typical ups and downs of the tail end of solar cycle 24… so propagation conditions have improved on the short wave bands …. Now back to the HENTENNA…

By the way, the first original report about the HENTENNA that went on the air here at Dxers Unlimited, dates back to 1999,more precisely, it went on the air the 12th of October of 1999, and according to my records, it then generated a lot of interest from our listeners, who were at that time, 1999, getting ready to enjoy the peak years of solar dream solar cycle 23 !!! >Never as powerful as super cycle 19, but nevertheless much better than the present very poor cycle 24.

So amigos here is at the request of Dxers Unlimited’s fans , a special Dxers Unlimited’s report on the HENTENNA, the Japanese elongated rectangular loop antenna with an easy match to coaxial cable feedlines of any impedance, be it 50, 60 ,75 or 93 ohms…or even 150 ohms !!! Of course that you can feed it with parallel transmission line of 300 to 450 ohms too, it is just a matter of minutes to find the perfect match for the feedline in use.

Let me start by saying that I recently built yet another HENTENNA for the FM broadcast band, and it is working nicely, having already picked up some Sporadic E skip DX stations from Mexico, the US and Puerto Rico during first few days of this year’s spring and summer E skip season.

Now you will have to learn something very unusual about the HENTENNA… the HENTENNA produces or receives VERTICALLY polarized waves when the antenna is placed horizontally; that is, with the long sides of the rectangular loop parallel to the ground. AND, if you want horizontal polarization, just flip the HENTENNA so that the long sides of the loop are vertical, and the short sides are parallel to the ground, something that is puzzling, but that’s the way it is amigos…

By the way, one of the world’s foremost antenna experts, Dr. L. B. Cebik, amateur radio operator W4RNL, did during his fruitful life an extensive analysis of elongated loops, and his findings are really fascinating. Dr. Cebik , now sorrily a silent key specialized in computer modeling of complex antenna systems, and his work with the HENTENNA and other similar elongated loops shows that the HENTENNA is a very good performer indeed.

In a few seconds, be ready to write down, the formulas for calculating HENTENNAS in the frequency range from 14 megaHertz all the way up to 220 megaHertz.

And now, as promised more about the japanese wonder antenna… the HENTENNA. Dr. Cebik’s computer modeling shows that the elongated loop HENTENNA has an edge over a regular square one wavelength loop and the regular elongated loop.

HENTENNAS for receiving FM broadcast signals are very easy to build, using a wooden or PVC pipe frame and copper wire. I built the one just
mentioned cut for 100 megaHertz, using PVC insulated no. 12 wire, the one that is typically used for home wiring.

The loop was closed by soldering with a butane torch, and using regular solder with rosin core… The reason for using the butane torch is that no soldering iron at hand here could handle the heavy wire PLUS the high speed heat transfer of the copper wire.

The loop for the 100 megaHertz antenna is 1.5 meters on the long sides of the rectangle and 50 centimeters on the short sides. The feed point for the 50 ohm cable is was found to be located about 55 centimeters from one of the short sides of the loop.

The antenna is installed with the long sides in a vertical position; for receiving horizontally polarized FM broadcasts. I tried both 50 ohms and 75 ohms coaxial cables, and could not detect any difference on the weakest station that I am picking up here regularly with the FM band HENTENNA.

Again, now please pay extra attention …if you want to make of these elongated loops for receiving, here are the measurements to use: for the long sides of the rectangle 1/2 of a wavelength at the operating frequency, for the short side, the length is 1/6 of a wavelength… and the connection point for the coaxial cable of 50 ohms impedance is a little more than 1/6 of wavelength from one of the short sides of the rectangle, and it must be found experimentally by locating the point that provides the minimum standing wave ratio.

HENTENNAS can be built for any frequency between 10 megaHertz and 300
megaHertz by using heavy WIRE, and for the frequency range from about 50 megaHertz to 500 megaHertz you may try building HENTENNAS with copper or aluminum tubing.

Hope to have you all listening to my middle of the week edition of Dxers Unlimited amigos and do enjoy the improved short wave propagation conditions now in progress, especially after your local sunset.

South Sudan: Eye Radio reaches new audience via shortwave

3 Replies

You might recall a post from Robert Gulley earlier this week about Eye Radio. Many thanks to SWLing Post contributor, Andrea Borgnino who shares a link to the following article from the BBC about Eye Radio’s broadcasts over shortwave:

(Source: BBC)

A radio station in South Sudan is using older, but tried and tested technology to reach new audiences.

Radio is a crucial medium in South Sudan, where illiteracy is high and many areas lack an electricity supply.

But many people living in remote villages are out of range of existing FM and mediumwave (AM) broadcasts.

Huge distances

To reach these potential listeners, Eye Radio, which is based in the capital Juba and can be heard in regional capitals, has just started broadcasting on shortwave.

The new service covers “the whole of South Sudan, including remote areas in which communities are not able to access FM radio”, says Eye Media head Stephen Omiri.

[…]The station is thought to be renting airtime on a transmitter based outside South Sudan.

Funding for the shortwave service comes from USAID, the international development arm of the US government.

[…]Eye Radio broadcasts in English, standard Arabic, and local languages Dinka, Nuer, Juba Arabic, Bari, Shilluk, Zande and Moro.

The shortwave broadcasts are on the air from 7-8 a.m. local time on 11730 kHz, and 7-8 p.m. on 17730 kHz.

Another station using shortwave to reach South Sudan is Radio Tamazuj, which is based in the Netherlands.

Edward R. Murrow Shortwave Transmitting Station: wallpaper images

8 Replies

On April 1st, I spent the bulk of the day at the Edward R. Murrow Transmitting Station outside of Greenville, North Carolina. Prior to my visit, I asked if SWLing Post readers had any requests or questions I could address while there.

I printed all of your inquiries and made sure they were addressed during my visit. I also took a lot of photos!

I had hoped to have a post published the following week with all of the photos and responses properly curated, but frankly, I haven’t had the spare time to do it yet. I’ve simply had too much travel and too many projects on my plate since that site visit (not to mention cramming for the Extra exam!).

I’m working on a draft of the post now and Macon Dail (WB4PMQ), the transmitting station’s Chief Engineer, is helping me with captions and responding to your questions.

Wallpaper

One reader asked if I could snap some photos that could be used as wallpaper on his computer. This morning, I selected eleven images and cropped them to fit a widescreen monitor.

I tried to pick images that would work well as a background/wallpaper–meaning, they’re not too busy (visually). Some are abstract close-ups.

Click on any of the images on this page to enlarge–then simply save the image to your computer to use it as you see fit.

I hope you enjoy!

New Shortwave Station in South Sudan

4 Replies

There’s a new shortwave station in South Sudan!
Kudos to Eye Media for their Shortwave Radio efforts in South Sudan to complement and extend their reach beyond local FM radio. And I must add, kudos to the United States for their part in helping to fund the venture. While I am quick to criticize my country for their cutbacks in SW funding, I have to be fair and say “well done” when something like this comes along. Here is the news report as posted April 26 (yesterday) on Radio Tamazuj and which was reported by Alokesh Gupta New Delhi on the Cumbre-DX Yahoo Group:

Eye Media, the parent organization of Eye Radio, has announced that it has launched a new shortwave broadcast service to complement its existing FM broadcasts in South Sudan.

The broadcasts starting today will bring listeners news and information in Arabic, as well as Dinka, Nuer, Shilluk, Bari, Zande and Lutoho.

According to a press release today from Eye Media, “the Eye Radio Shortwave will cover the whole of South Sudan including remote areas in which communities are not able to access FM radio stations.”

Eye Radio is one of the fastest expanding media houses in South Sudan after launching FM repeaters in several state capitals last year, expanding the station’s reach beyond Juba where it is based.

In its press release, the station noted that the funding for this initiative came from USAID, the international development agency of the US government.

Shortwave radio is used for long distance communication by means of reflecting or refracting radio waves back to Earth from the ionosphere, allowing communication around the curve of the Earth. It was a popular means of long-distance news sharing before the advent of the Worldwide Web, and it is still used for reaching remote areas.

Only two other media houses broadcast on shortwave with content specifically for South Sudan: Radio Tamazuj, which operates two hours daily on the shortwave, and Voice of America, which produces the 30 minute program South Sudan in Focus.

Radio Tamazuj broadcasts from 6:30 to 7:30 each morning on 11650 kHz on the 25 meter band and 9600 kHz on the 31 meter band, and 15150 kHz and 15550 kHz on the 19 meter band each evening from 17:30 to 18:30.

Eye Radio’s new broadcasts will run from 7:00 to 8:00 each morning on 11730 kHz on the 25 meter band and 17730 kHz on the 17 meter band from 19:00 to 20:00.

Curating a list of endangered shortwave stations

2 Replies

That’s my minivan parked in front of the RCI Sackville transmitting station in June, 2012. The site was closed by the end of 2012 and towers demolished shortly thereafter.

Recently, my friend and fellow archivist, London Shortwave, and I engaged in a discussion about creating a curated list of “endangered” shortwave radio stations.

The idea being we could use such a list to focus our efforts and those of the archiving community on recording broadcasters that were most likely to disappear in the near future.

London Shortwave published an excellent post about this on his blog.

Please click here to read his post.

We quickly put this page on the Shortwave Radio Audio Archive as a starting point.

We need your help to curate this list!

Please comment either on London Shortwave’s blog, or on this post, and suggest any additional broadcasters we may have missed. Please include a link to news item(s) which may indicate the broadcaster faces closure.

Of course, this list and the categories are subjective–we’re simply using our best judgement in this process. Often, broadcasters can shut down with little or no notice.

Thanks in advance for your help!

Radio Vanuatu on target for nationwide coverage under new leadership

19 Replies

(Source: Radio New Zealand via Mike Terry on the WRTH FB Page)

The recently appointed chair of the board of the Vanuatu Broadcasting and Television Corporation is confident nationwide coverage will be achieved by Radio Vanuatu soon.

The new government recently replaced the old board following concerns over the lack of the public broadcaster’s ability to reach the outer islands.

Its new chairperson Johnety Jerety said transmission had deteriorated over the years, mostly because of poor maintenance.

He said under the government’s hundred day plan nationwide coverage had to be implemented by July 1st.

But Mr Jerety said part of the problem was that people were buying cheap radios.

“They’re not compatible to meet the standard for our transmission system within here so that is why most of the ni-Van [indigenous people] within the islands are not able to have the coverage received throughout the island.”

Johnety Jerety said they were now advising people to buy short-wave radios that are compatible.

Read this article on Radio New Zealand’s website.

This article is a little vague, but I assume when the new chairperson, Johnety Jerety, is claiming that the problem with reception has to do with “cheap radios” perhaps he means receivers that don’t cover Vanuatu’s nighttime frequency of 3945 kHz? Almost all radios with shortwave should receive their 7260 kHz frequency. Of course, perhaps he simply means that fewer and fewer listeners are purchasing shortwave radios?

Vanuatu is certainly being heard around the world–indeed, only two days ago, SWLing Post contributor, Paul Walker, was over the moon when he snagged Vanuatu on 7260 kHz from Galena, Alaska. Paul wrote:

I bagged my most wanted shortwave station ever tonight!

Radio Vanuatu on 7260!!!! Heard something under a bunch of Asian hams. [Q]uite good considering they are only running 1.5 kw out of their licensed 10 kw (that’s what they told me after the cyclone awhile back).

Great catch, Paul!

I’m happy to read that Vanuatu is investing in their station once again.
