Shortwave Descends on
The B10 HFCC/ASBU Conference
By Jeff White
Our trip to
This was the
semi-annual seasonal conference where shortwave frequencies were coordinated
on a worldwide basis for the B10 (i.e. winter) season which begins on October
31, 2010 and runs through March 27, 2011.
The NASB co-sponsored the conference along with our longtime associate
member Thomson Broadcast & Multimedia, based in Turgi,
about 40 minutes northwest of

At the opening plenary, Sergio Salvatori of Vatican Radio gave details of the technical procedures to be used during the week.
After a coffee break, the actual frequency
coordination process began. The NASB
sponsored the high-speed Internet service at the conference. The hotel provided a main Internet connection
to the conference secretariat room, and a server in the secretariat was
connected to a wireless network in the main conference meeting room with the
HFCC/ASBU Intranet content.
Unfortunately, despite extensive tests of the conference Intranet
network during the days prior to the conference, there were serious problems
when the approximately 100 laptops began using the network
simultaneously. Internet connectivity
was sporadic at best. The hotel's
technical staff began working immediately with Vladislav,
Gerald Theoret of CBC, Sergio Salvatori
and other HFCC personnel to try to find the problem. The Movenpick
chain sent its IT expert to the hotel to work on the matter also. But after nearly four hours of trying to
resolve the matter, it was still not working.
In order to avoid a major problem, the hotel offered to let all
conference delegates connect to its wireless Internet directly, so
participants were able to upload schedules to the HFCC's duplicate server in
The HFCC/ASBU Conference ran Monday through
Friday, August 2-6. Most of the
meeting consisted of the usual uploading of frequency schedules for the B10
season, processing data, producing “collision lists” and negotiating
solutions to the collisions between stations.
But on Tuesday afternoon, there was a one-hour DRM session presented
by Ludo Maes of TDP,
Horst Scholz of Deutsche Welle
and Mireya Martinez of TDP. Ludo began with
an overview of the DRM Consortium and an explanation of Digital Radio Mondiale's features, benefits and global receiver
strategy. He explained that state
broadcaster All India Radio has recently chosen DRM for the digitalization of
its vast mediumwave and shortwave network,
including the purchase of five new shortwave transmitters and a 500-watt DRM
transmitter for 26 MHz trials.
Next, Ludo Maes had a presentation about DRM monitoring systems. As he explained, “there are many different systems available for monitoring DRM broadcasts. Each system has its own specific tools, advantages and disadvantages. For incidental, free of charge monitoring, the data on the DRMrx forum will provide the perfect solution. In case a more dedicated, scheduled monitoring is desired, the Theseus, RFmonitor or IBB DRM monitoring systems will certainly fulfill your needs.” For more details, you can e-mail Ludo Maes at firstname.lastname@example.org.
The third major part of the DRM presentation was the results of a recent survey of European international broadcasters about multistandard digital radio receivers. Here is Ludo Maes' background to the survey and summary of the results:
“A major issue regarding the success of digital radio is the availability of cheap digital radio receivers. A digital radio receiver can only be produced at a low price if it can be produced in large quantities. A multistandard digital radio receiver (having the major digital standards onboard) can be sold in every country around the world. This allows for mass production and minimizes the risk for receiver manufacturers since they can sell the same receiver in any market. The appearance of multistandard digital radio chipsets is the key.
“The intention of the survey was to find out the opinion of radio broadcasters towards the idea of multistandard digital radio receivers. In this survey, the major European radio broadcasters were contacted, asking them only 2 questions [Do you support the idea that a multistandard digital receiver would be a good step forward for digital radio to become a success? And, if multistandard digital radio receivers would be available, which standards should be included in your opinion?] Of the 31 countries contacted, 28 responded to the survey. The results of the survey can be useful to the radio receiver and chipset manufacturing industry, as well as to the broadcasting unions and the radio broadcasters themselves. Hopefully this will give confidence to the industry in order to invest in the idea of multistandard digital radio receivers.”
The conclusions of the survey: “Broadcasters are very much in favor of multistandard digital radio receivers. All of them find it important to have analogue FM aboard, but analogue MW and analogue SW not too much. DAB+, DRM and DRM+ are considered the most important to be included in a multistandard digital radio receiver, followed closely by DAB and T-DMB. HD-Radio and other digital standards (like wifi-radio, DVB-H and DVB-T) are considered the least important to be included.”
Mireya Martinez of TDP gave a
presentation about the plan to create a European International Broadcasters
Group to promote the use of DRM. The
idea is to include broadcasters which transmit programs in six primary
European languages – English, German, French, Russian, Spanish and Italian. “All in all,” explained Mireya, “English either as a mother tongue or as a
second/foreign language is spoken by 51% of EU citizens, followed by German
with 32% and French with 28%.” The
presentation included a list of international broadcasters in
For example, 14 out of the 46 European international broadcasters transmit in Spanish. But only one out of the 14 international broadcasters which transmit in Spanish is using the DRM standard. “This means that there are still 13 potential international broadcasters in Spanish which have the possibility to broadcast in DRM,” said Mireya. “The proposed strategy is to get in contact with those 13 international broadcasters and encourage them to broadcast in DRM.”
of the 46 international broadcasters are currently transmitting in DRM: BBC, Deutsche Welle,
Radio Romania International, the Voice of Russia, Radio Prague, Polish Radio,
Vatican Radio, RTL Luxembourg, Radio France International, Radio Exterior de España and RAI from
The Wednesday, August 4, coordination activities ended early so that all of the delegates could take part in a tour sponsored by Thomson Broadcast & Multimedia. Three large buses took the group from Regensdorf to the Thomson plant in Turgi, some 45 minutes away. The delegation was broken up into five groups to visit five different parts of the vast multi-building campus of the plant. The five tour divisions were:
1) An overview of antennas and masts and a look at the rotatable curtain antennas.
2) An overview of the M2W mediumwave transmitter family, a presentation of the 10-kilowatt M2W transmitter, an explanation of the DRM Skywave product line, and a live demonstration of the new DRM application called Diveemo.
applications for scientific and medical installations, including an
innovative RF amplifier system for cancer therapy which is being used in
4) An overview of the Thomson shortwave transmitter line, a presentation of the 250/500 kilowatt shortwave transmitter, and a PSM modulator.
5) Historical information about Turgi, presented by recently retired Thomson employee Sally Welter (see sidebar story), whose presentation received applause from the group of visitors.

explained that the
Back in Regensdorf on Thursday, the frequency coordination process continued. On Thursday afternoon was the Plenary Meeting. Horst Scholz reminded everyone that the A season conference alternates between Asia and the Arab countries, so the next HFCC/ASBU conference in February of 2011 will be in an ASBU country, although the exact location has not been decided yet. There was also no host yet for the B11 meeting in August of next year.
Geoff Spells reported on ITU working groups, DRM work going on in the CEPT (European Conference of Postal and Telecommunications Administrations), a CEPT report on the future of terrestrial broadcasting, and fears that PLT (powerline transmission) interference on the HF bands could be much worse than currently expected. Gerald Theoret reported on the Group of Experts meeting which took place during the HFCC Conference. The main topic at this meeting was how to deal with future Internet connectivity problems such as those experienced on Monday of this week.

Oldrich noted that the HFCC
global database is the best source of information for shortwave listeners,
but the data is still not accurate enough, so steps need to be taken to make
it more accurate. He pointed out that
a decision was made at the last HFCC/ASBU conference in
“Shortwave and Internet will not be fighting each other, but complementing each other,” explained Oldrich. “We are facing critical developments in reducing the budgets of shortwave stations. We can't reinstate stations to the 'glory days' of earlier years, but we should maintain them at reasonable levels.”
In his review of financial matters at the Plenary Meeting, Geoff Spells reported that the HFCC had a relatively healthy balance of accounts at the end of 2009. “The HFCC is solvent, with a cushion in the bank,” he said. This is due to a recent increase in membership fees, and members responding to the economic crisis by paying any past due amounts. For 2010 Geoff said that the financial situation looks OK.
The registration desk at the HFCC/ASBU Conference was staffed by the NASB – primarily by Thais White of WRMI, who was ably assisted by Judy Tapley, wife of Glenn Tapley of WEWN. Elena Glutz of Thomson Broadcast & Multimedia also assisted on the opening day, August 2.

Conference Opening Remarks by Oldrich Cip. HFCC Chairman
Special thanks of all of us go to Jeff White, President of the NASB who has volunteered as the chairman of the preparatory committee and has taken over conference registrations, contacts with the hotel, etc. I hope that Jeff's fancy for the HFCC will stay also after the conference since he is a great writer and we need more content on the HFCC website.
have only one subject for my usual opening remarks. It follows up on our discussions in
The programme delivery modes of audiovisual media are becoming more varied and fragmented. The digital delivery – so-called broadband – is widely considered as the leading technology for the future. But there is also other evidence: “Terrestrial broadcasting in many countries is still, and will remain in the future, the main way to guarantee universal access to radio and TV content for fixed mobile and portable devices. No other single platform can replicate these benefits.” This has been the conclusion of the experts of the European Broadcasting Union in a debate on the radio spectrum policy earlier this year. According to that report the maximum benefit for both broadcasters and viewers would be the combination of terrestrial transmissions and Internet with the aim of offering the full range of benefits of both technologies.
Unfortunately there is no such in depth debate yet in international broadcasting. In the present rush to embrace new digital platforms, decision makers have been moving funding from shortwave broadcasting. Yet they are frequently unaware of the properties of the individual platforms and even of the existence and needs of different segments of their audience.
It would be futile to believe that the HFCC alone will be able to keep shortwave delivery in the forefront of options but we are certainly in a position to provide vital information about shortwave broadcasting and about its merits both for those who will carry on listening to shortwaves in combination with other delivery modes – and to those who consider shortwave listening as their hobby, and also to broadcasters who need facts and information for their effort to keep shortwave programmes on the air.
Broadcast bands are allocated internationally and a programme offered in a shortwave band is in a much more unique position than a programme placed on the Internet where there are huge numbers of stations and other attractions. The availability and quality of shortwave delivery is independent of the number of listeners. New technologies frequently incur additional costs and do not provide coverage in some locations. Shortwave delivery is free-to-air and free of any charges.
Most of our regular and associated members are interested in how shortwave technology develops in the future, and what is the current state of digitization that could introduce such a dramatic improvement in sound quality. We are ready to collect and publish on the web all information that will help create a balanced and stable system of programme delivery where the distribution platforms do not compete but complement each other.
We are ready to promote shortwaves. But our HFCC tools and what we do also determines quality. Very sophisticated collision processing tools are used but some members still keep over-submitting their frequency requirements. This is in conflict with the spirit of co-operation that has been established over the years. We can discuss this further during the Plenary Meeting since the HFCC management believes that now is the time to take action beyond what we have tried in the past.

Shortwave Station News from the HFCC/ASBU B10 Conference
U.K. - London-based World Radio Network is selling airtime on FM networks in Turkey (over 28 outlets in major cities like Istanbul, Izmir and Bursa), Afghanistan (reaching listeners in Kabul, Habat, Jalalabad, Mazar-e-Sharif and Kandahar) and Buenos Aires, Argentina (two stations – one with 30 kW and the other with 60 kW ERP).
My name is Sally Welter and up till the end of 2009 I was employed by Thomson Broadcast & Multimedia AG, where I worked together with Willi Tschol.

areas on top of the hill behind the train station.
Especially young families find Turgi an attractive place to live in: it’s quiet and rural, close to
larger urban areas and has a very good public transportation system thanks to the train
Back in the
very old days, when the
Turgi was no more than a spot on one of the main Roman roads crossing the country from
east to west.
In 1534, a
farmer who was plowing his fields close to Turgi
found a Roman milestone dating from 99 BC. This stone had a Latin inscription
on it, giving the distance from here to the Roman city of
A Roman mile represents 1.48 kilometres and the distance as given on the milestone was measured later on and found to be correct.
In the beginning there was no bridge across the river, but there used to be a ferry which connected one side of the river with the other. And up until the beginning of the 19th Century, the ferryman who had his house here was the sole inhabitant of the area known today as Turgi.
industrial revolution and the invention of mills invaded
Turgi was a perfect location for mills. The town itself is something like a peninsula with two-thirds
of its area being surrounded by the river Limmat
which curves all around it. In
addition, just around the corner, three main Swiss rivers merge together,
forming one of the largest sweet water reservoirs in all of
In the 1820’s, the industrial family Bebié moved to Turgi, laid the cornerstone of their first cotton spinning mill and built the canal to provide the mill with water. Soon they built a second mill, large houses for feeding and lodging their workers, as well as a factory school for all the children who worked at the mill and a private school for children under 13 years of age. At that time, child labour for children above 13 years of age was not against the law, and the mill was happy to employ children to insert and set up the spindles.
In 1858, the
cotton spinning mill here in Turgi was the largest
of its kind in
Till today most of the buildings erected back in those days are still around, including many beautiful mansions. The building here was the mill. The house down there used to be the barn where the cotton was stored and just across the street you can see the building which is called “The Farmhouse” and which was indeed a farm grounded back then by the Bebié Family. The farmhouse was taken over by the town and is used today as a cultural and youth center.
The buildings situated on this factory area now stand under monument conservation. They can be remodeled and modernized inside, but the facade must be kept the same. A few years ago, Turgi received the highly coveted prize called “Wakker Prize”. This is awarded by the Swiss national government to towns who have excelled in heritage protection.
The town annals tell an interesting anecdote about a special factory clock used in the mill. A normal working day back in those days was 14-15 hours with a half-hour lunch break. The mill owners were very strict about having the working day start at 6am and end at 9pm. On the other hand, they wanted to avoid having to light lamps, since these could easily cause a fire with all the cotton. They solved this problem by setting the clock weekly to match the daylight time. In July for instance, when the clock showed 6am and time to start work, it was actually only 4.30 am, and in January, when the clock showed 6am it was already 7am. The workers were forced to set their clocks regularly to match this factory clock which was mounted high up in a bell tower making it visible from far. This clock by the way still exists and is exhibited in the restaurant behind the bridge.
In the 1880’s the mill experienced a financial crisis. The owner successfully reshaped the business by building two power plants. The first one here in Turgi was situated next to the mill; the second one was a little bit further down the river. They also built a power transmission line connecting the two power plants. By the way, this power transmission line enabled the construction of the first factory in the
region not to be situated directly on the riverside. This factory for metal goods, which was next to the train station, was torn down years ago.
The power plant built back then was a little bit further up the river and consisted of two buildings: The turbine building on top of the canal and the generator house on the little island. The island by the way was created when they built the canal which intersected the northernmost tip of Turgi.
The power plant had 2 Francis turbines. Here you can see parts of the old turbine, like the fin-set and the old gearwheel which had wooden teeth! Can you imagine: a leather belt drive went all the way from the turbine - over the river - and drove the generator on the island.
When the mill closed, the electricity was used to supply the public network. About 30 years ago a new power plant was built. This is in operation today and delivers a maximum of 950 kW. It has a Kaplan turbine which drives the generator with about 110 revolutions.
The Limmat Power Plant Network supplies its regional
customers with 30% of their total energy needs using water power coming from
four hydroelectric plants on the
In Turgi the era of the mill and the Bebié Family finally came to an end in 1962, when the expanding Company Brown Boveri of Baden took over the entire share capital of the Bebié AG. The industrial revolution of the 19th century thus made way for the electronic industry of the 20th and 21st centuries.
In addition to taking over the existing spinning mill buildings, Brown Boveri – later known as Asea Brown Boveri or ABB - built new factories on the other side of the river and moved their entire electronic activities there. Soon the area became known as the “Silicon Valley of Switzerland.”
In the old mill itself, Brown Boveri installed their factory for radio broadcast transmitters, where it has stayed until today, in the meantime better known under the name “Thomson Broadcast & Multimedia AG”.
The conference package included a daily buffet breakfast at the Movenpick Hotel, which included many hot and cold items such as Swiss specialties rosti (like hash-brown potatoes) and a variety of fresh Swiss cheeses. For lunch and dinner, the hotel had a main restaurant (where the least expensive entree was a hamburger for about $23) and an Italian restaurant which specialized in dozens of types of spaghetti which were very good and reasonably priced, by Swiss standards.
who preferred a slightly less expensive alternative could nip into the Migros supermarket in the shopping center right next door
to the hotel. Migros
had a cafeteria-type restaurant with daily specials. Another alternative was the Gasthof Hirschen, a small
traditional guest house hotel a short walk from the Movenpick. The restaurant there was not any less
expensive than the Movenpick, but it had Swiss
specialties like Kalbsfleisch Zurcher

before we leave this subject, I would like to share a traditional fondue

Kaethy's Fondue Recipe
Rub a clove of garlic around the caquelon (fondue bowl).
2) Put 150-200 grams of Swiss cheese per person into the bowl, cut into small pieces. There are many variations, but the cheese should be, for example, half gruyere and half another variety like Appenzeller. Vacherin is another variety which is often used, and makes the fondue creamy.
3) Add two to four teaspoons of Maizena or potato starch. Be sure to add this before heating; otherwise it clumps.
4) Add one deciliter of white wine per person. Fondant is the preferred type, but any dry white wine like Riesling will do in a pinch.
5) Add one to two teaspoons of lemon juice.
6) Throw in a bit of nutmeg and pepper to taste.
Then heat the mixture until the cheese is melted and creamy. Cut fresh bread into small pieces and dip them into the fondue mixture, which is set on the table with a candle or heat canister underneath it to keep it warm.
