Interview with Daniel Walsh

Daniel C. Walsh is an assistant professor at Appalachian State University in the Department of Communication. He wrote the book "An air war with Cuba: The United States radio campaign against Castro" (publisher Mcfarland) and he accepted to be interviewed.
1) Where and when were you born?
I was born in Greenville, North Carolina, USA December 2, 1969.
2) What is your first memory of listening to a radio?
I guess my first memory of listening to a radio is riding around in my mother's station wagon. I also remember as a child playing radio station where I would pretend to be a radio announcer and introduce records on a turntable. When I got older I put a walkie talkie up to the stereo speaker and then would go to another room with the other one to make it seem like a real radio.
3) When did u become interested about US propaganda towards Cuba?
I became interested in U.S. propaganda for Cuba when I was in graduate school at Marshall University. I needed a research topic for one of my classes and thought it would be interesting to examine Radio Marti. I thought it was interesting that the United States spent a lot of money on a Radio Free Europe type station for Cuba yet Fidel Castro was still in power. I created a proposal for evaluating the effectiveness of Radio Marti but never actually did the study. A few years later, the Elian Gonzalez custody battle forced people to think about relations with Cuba again. I thought the topic should be studied and wished I could have actually completed the study I proposed. When I was getting my Ph.D. at the University of South Carolina a few years after that, I began thinking about picking up where I left off. The United States and Cuba were still adversaries and Radio Marti was still on the air so I thought it was a legitimate topic.
4) In Cuba there is a dictatorship, how difficult is it to get fair reports about audience studies in Cuba?
Research of Cuban audiences is extremely difficult. One of the primary ways in which the United States obtains information about radio listeners in Cuba is by interviewing immigrants to the United States. The validity of these results is questionable. A Cuban who decides to leave the island and come to the United States may not be a typical Cuban. That person has demonstrated positive feelings toward the United States. One would assume they might be more likely to have positive feelings about Radio Marti as well.
There is a television version of Radio Marti called TV Marti. Practically no one has seen it because the Cuban government has jammed the signal. Radio Marti gets through because a radio signal is more difficult to jam. Officials at the U.S. Interests Section in Havana have conducted their own research in Cuba regarding TV Marti and found that most people on the island cannot see it.
A few years ago the U.S. did a telephone survey of people in Cuba and asked them if they listened to Radio Marti. Most people said they did not. A lot of these people thought that the phone calls were from Cuban officials testing their loyalty to the revolution. A people of the interviewees asked that someone from the government stop by to repair some things. It was obvious that they thought the interviewer was a Cuban official.
5) You are building an archive of international broadcasts, which are the main radio stations in your archive?
The archive of international radio broadcasts was supposed to include Voice of America, Radio Marti, the BBC, Radio Vatican, and as many other radio operations as possible. When I tried to analyze Radio Marti for my dissertation I found that I could not obtain recordings of the station. The 1948 Smith-Mundt Act makes it illegal for the federal government to release recordings of radio broadcasts of Radio Marti, VOA, Radio Free Europe or other operations to U.S. citizens. This stipulation was included in the 1948 to prevent the federal government from being in a position to disseminate propaganda to the domestic population the way the Nazis did prior to WWII. The restriction was still in place more than 40 years later.
The law makes no sense in that it only prohibits U.S. officials from releasing recordings or transcripts of programs to U.S. citizens. It does not prevent a U.S. citizen from having these materials. U.S. officials are allowed to disseminate these materials to people outside the United States. The broadcasts encourage listeners to request the materials. What this means is that a U.S. citizen who wanted a recording of a Radio Marti broadcast could have someone in Canada request the information and then mail it back to the person in the U.S. This is legal. That's what I did. to get recordings of Radio Marti. The interesting thing about it was I got the idea from people at the Broadcasting Board of Governors, the people that originally originally told me that they couldn't release the materials.
This made no sense to me. I also realized that it made it extremely difficult to research these stations. There is almost no transparency and no way for the public to hold the stations accountable. I thought it was ironic that we fund the broadcasts but cannot listen to them. I thought it would be easier for people like me who wanted to analyze international radio broadcasts if there was an archive of recordings. Vanderbilt University has an archive of television news programs dating to 1968. I was trying to do the same thing for international radio.
The archive is currently on hold. In December of 2010, I contacted some amateur radio groups about recording programs and contributing to the archive. One person said my proposal was a scam and accused me of trying to manipulate people into bypassing copyright restrictions. Most international broadcasts are in the public domain. This person also told me that he or she would be turning my name over to the FBI, CIA, FTC and other authorities. I don't think what I am trying to do is illegal. I contacted officials in Washington who didn't really give me a definitive answer. They said that some of the material is copyrighted because it comes from people contracted to produce content. They didn't say much more than that. I have suspended the operation for now (no recordings were ever collected). I am hoping that some people will express interest and offer to help. No one has so far.
6) Do you think that propaganda radio stations are still useful ?
I do not believe that radio broadcasts are effective propaganda tools in that they cannot "force" a population to overthrow a government. There are examples of how radio broadcasting can be used to create a false sense of reality but that is only if the person is willing to believe. Radio propaganda cannot cause a person to do or believe something the person does not want to do or believe. I think Cuba is the perfect illustration of this. The United States has bombarded the island with propaganda for more than 50 years and the people there have not taken up arms against their government. They don't want to.
I believe that there is still a need for informational (not propaganda) international radio broadcasting. In the early years of Radio Marti, the station covered stories on AIDS and the Chernobyl disaster. Neither had not been covered by Cuban media. The Internet and social media have diminished the role of radio broadcasting in developed parts of the world but not in some of the underdeveloped areas, which tend to need the information more than anyone. Cuba has Internet access but it is limited and often monitored by the government. I think radio also overcomes literacy barriers, which is still a problem for many regions. Until the Internet can be perfected and eliminate the reading requirement, there will be a need for international radio.

Interview with Gunnar Garfors

2) What is your first memory of radio?
The first thing I remember from the radio was the news about the Alexander Kielland oil rig that capsized in the North Sea on March 27, 1980, killing 123 people. My mom was pretty much in shock, something that made a big impression on a four year old. I remember the scary atmosphere and both the news reader and the reporters being very much effected of what they were reporting. I really started appreciating radio when I was a little older. My parents gave me a FM/SW/MW/LW radio that I used a lot and that taught me to love the power of radio and the great pictures it created. I listened to sports, quiz shows and youth programs from NRK (Norwegian Broadcasting Corporation) and to SW broadcasts from BBC and Radio Ulster in particular. The latter were playing great music and had a funny DJ at the time I was supposed to be sleeping.
3) What is your opinion about digital radio? Do you think it could work in any country?
Digital radio is a major part of the radio future. It opens up for more radio channels, easier navigation, better coverage and a lot of additional services that work together with the internet and open up for exciting opportunities when it comes to functionality and revenues. It can undoubtedly work in any country. We see that the de facto standard for digital radio, DMB/DAB/DAB+ is being adopted in over 40 countries. The standard is advanced, widespread, mature, already here and it secures equal digital opportunities for everyone.
4) Some experts like Grant Goddard (i interviewed him last year ) are skeptical about the transition to digital radio; what do you think about their views?
I do not consider Grant Goddard an expert in this field. He certainly knows radio from the content side, maybe he should concentrate on that. He portrays himself as a skeptic in order to get PR which he needs for his consultancy business. The best way he can get PR is to distance himself from broadcasters, listeners and advertisers. By doing that he gets to be the guy the media calls to get “the other view.” But what will he do when radio has gone digital, as is about to happen in Norway (FM switch off in 2017), Great Britain (announcement of switch over expected in 2013), Denmark (Minister of Culture wants to switch off FM) and other countries? I think he may be better off staying an expert on content and formatting, even though it will get him less airtime. His views are anyhow extremely conservative, at best. He is doing his best to prevent the transition radio needs, to go digital as the last media out there. Why does he not want to give everyone equal opportunities when it comes to radio? I want more choice, more money to better programs, better reception and easier usage. It is even much greener too. The transition for TV went smoothly, now providing better choice and quality to the vast majority of people. Many people will have to get new radios or to have them adapted, but this is also the case for all other receivers. People do for instance change much more expensive devices such as mobile phones and computers every 1-3 years. Why are radios different in this respect?
5) You are in favour of switching off FM; what should we do on 87,5-108 MHz?
Power companies are looking at these frequencies as a way of transferring data about electricity usage. Other machine to machine communications could also use these frequencies. Frequencies will in any case always be attractive. Offer them to businesses, and there will undoubtedly be good ideas.
6) What do you think of DRM (Digital Radio Mondiale)? Is there a future for digital radio below 30 Mhz?
DRM is great as a complement to DMB/DAB/DAB+ if you are looking to cover vast areas with few people with one or two radio stations. The DRM consortium should push for receivers that combine DMB/DAB/DAB+ and DRM. That way, they will be able to ride on the wave of the digital radio movement we are currently seeing. For DRM to stand on its own will be very difficult as I don’t think it in an isolated manner can compete from technical, financial or functional points of view.

Interview with David Hendy
David Hendy is a media historian with a broad interest in the social and cultural impact of broadcasting and cinema over the past two centuries; he's a reader in media and communication in University of Westminster.
He wrote the books Radio and the Global Age (2000) and Life on Air: a History of Radio Four (2007).
I had the chance of interview him.
1) When and where were you born?
I was born in 1962 in the small city of Wells in the west of England - and spent most of my childhood in the region.
2) What is your first memory of radio?
I suppose I remember being a small child, maybe about 2 or 3 years old, playing in the kitchen while my mother did the housework. While she loaded the washing-machine or prepared the evening meal, the radio would be on. It was mostly speech radio, so I'm guessing it was the BBC's old 'Home Service', which included news and plays and discussion programmes, plus a little music every now-and-then. And I can remember sitting next to the radio set one day in particular, to hear my father, who was being interviewed for some reason or another. But it wasn't until I was about ten or eleven that radio's peculiar magic took hold of me. I’d just rescued an old Bakelite radio set from my parents’ attic and installed it next to my bed. I listened mostly at bed-time, when the lights were off. My ear would be pressed hard against the cloth-covered loudspeaker, so the volume could be down low and I could evade discovery. In the darkness, I was transfixed by a small, round, blood-red bulb fixed to the dial. It pulsated into glowing life, decayed into invisibility, then into life again, as I turned slowly through the frequencies to try to catch the faint chatter of distant voices. Out of the electromagnetic swell of white noise, I heard programmes from Paris, Hilversum, Rome. But the ones that gripped me the most were from the other side of the Iron Curtain: Radio Tirana, Radio Moscow… Radio Peking. I can’t remember what they said. It didn’t seem to matter. What mattered was that as they spoke, I felt connected by a gossamer thread with someone 5,000 thousand miles away. As a teenager, then as a student, I briefly lost this connection with radio - I was, I suppose, too busy with other things. But perhaps subconsciously, something of this earlier experience remained, to be re-awakened later, in my late-20s.
3) How much time did you need to write the books Radio in the Global Age and Life on Air?
There are two very different answers to this. In the sense of actually sitting down and writing, Radio in the Global Age took about 1 year. But I started writing it only after several years of working at the BBC and several more years teaching about - and subconsciously thinking a lot about - how radio worked and what it's importance was. So in another sense, Radio in the Global Age was several years in the making. For Life on Air, again, I was drawing, in one sense, from many years of working in radio, listening to radio, talking to radio practitioners, and thinking about the subject. But in practical terms, I spent about a year planning and scheming and doing initial research, then about two years researching in the archives full-time, and finally another two years writing - so about five years altogether, though with some teaching and other work during this period.
4) What is your opinion about digital radio?
I feel ambivalent about digital radio. There's no doubt that digital phenomena such as podcasts and the ability to 'listen-again' to radio has improved my life in many ways. I no longer fear missing my favourite programme on, say BBC Radio 3 or BBC Radio 4: I simply subscribe to it as a podcast and then listen to it when driving the 50 miles or so between home and work. Sound quality's improved, too - and that makes a real difference when listening to music or drama. On the other hand, there are features of the digital revolution that have made little difference to me. Choice is supposed to have multiplied exponentially - but that, I think is more illusory than real, because so many of those who run radio stations are too unimaginative about the medium's possibilities and therefore end up producing programmes that all sound very much alike. Of course, Internet radio makes it theoretically possible to listen to any station or any genre of output from anywhere around the world. And, occasionally, I have taken advantage of this facility, tuning in to, say, a college radio station in the US. But, more often than not, I have experienced no real feeling of 'connection' to such stations. Finding them satisfies an idle curiosity, much as finding radio from beyond the Iron Curtain did when I was a child. But at some crucial psychic level, radio maintains a distinctive 'national' or local bond with its listeners. Perhaps it's because, in Britain, we have the BBC, which is a phenomenal resource that we take too much for granted, yet which has infiltrated British life to an extraordinary degree. Whatever the reason, I miss the BBC terribly when I am abroad. In 2010 spent a lengthy period working in the United States. But despite it being the land if infinite choice, I struggled to find any station - commercial or public service - which gave me pleasure in the way that BBC Radio 3 or 4 have done for years, and will continue, I hope, to give me pleasure for the rest of my life. And, one of the reasons these stations give pleasure, is that in a profound way they are a 'gift' - given to me without any expectation of me having to respond. There is value in passivity. It creates the space to absorb and to think. And there is danger, sometimes, in a forced 'interactivity that removes the opportunity for reflective space. To use the old radio metaphor, we sometimes need to stop 'transmitting' in order to enjoy simply 'receiving'.
5) Are you working on another book?
I'm currently working on two books. Almost finished is a small book called 'Public Service Broadcasting' for publication in 2012. It tries to explore what public service broadcasting is in terms of its role in civic life. My second book, much bigger in scale, is 'Media and the Making of the Modern Mind', which will be published by Oxford University Press in 2014. It explores the ways in which four 'new' media - radio, cinema, television and the internet - have each in turn changed the ways we think and have understood the world over the past 120 years. Some of the ideas in the book were explored, more briefly, in a five-part radio series I presented for the BBC in 2010, called 'Rewiring the Mind'.

Interview with James Cridland
James Cridland is an english radio expert and a conference speaker, he's managing director of Media UK and he blogs at James Cridland's blog.
I had the chance to interview him.
1) When and where you born?
I was born in London in 1971: the year that the mandatory radio licence was abolished in the UK. It was another two years before commercial radio started broadcasting.
2) How and when did you discover your interest in the radio?
I saved up vouchers from a box of breakfast cereal, and sent off for a free radio. It arrived (in the shape of a box of breakfast cereal itself). I used it for a few hours on the first day I got it, and was very disappointed as I went to sleep: I thought it had ran out. "How does the latest news get in there?" I wondered. "How will it get the latest music? I'll have to buy a new one." The bug had bitten me: and from then on, I was determined to work in the industry.
3) When you were growing up, which radio stations were you listening to?
Radio 4, like my parents - it's a serious news and speech radio station and I felt very grown-up listening to it. Then I listened to a small local private radio station, Signal Radio, when it first launched: and I was hooked on the idea that this station was coming from just down the road.
4) What is your opinion about the transition towards digital radio (DAB,DAB+,DRM, etc)? Do you think that FM-band should be switched off by law (like the british government suggests)?
It's helpful that the government has indicated that simulcasting between FM and DAB should cease. However, in my opinion, the only people who should decide whether analogue radio should be switched off, I believe, are the radio broadcasters. It is not the government's place to commit mass-murder on an ailing commercial radio industry by forcing them to switch off their FM frequencies.
My post in the blog has more on this.
I believe that the future of radio is a multi-platform future: one that includes FM, DAB, and the internet. I also believe that broadcasters should take far more of an interest in the receivers, since it is in their interest to ensure that these are "platform-blind". The listener should not care whether their favourite radio station is on FM, DAB, DRM or the internet: they should just be able to listen. It's silly, in this era of content, to expect listeners to know whether their favourite radio station is on FM or DAB: it should just appear, by name, on their radio.
Apple, Sky, Canal +, Freeview, and many other broadcasters and content providers are working hard to ensure a standard, simple user interface to access their content. It appears odd that radio broadcasters are not doing so.
5) How do you imagine the future of radio?
The future of radio is a multi-platform future.
We have to have broadcast radio to reach hundreds of thousands of people at the same time: the internet can't do that.
We have to have more than one broadcast standard to offer the choice people expect.
We have to use the internet to deliver on-demand content and personalisation; and niche, out-of-area content.
And we have to have all this in one, easy-to-use, device that we'd like to call a "radio".
The future of radio isn't on-demand over live; internet over FM; personalisation over a linear stream - it's all of these things. That'll help keep radio fresh and exciting.

Interview with Grant Goddard

Grant Goddard is one of the best expert of radio and he runs a very interesting blog about radio and its evolution in UK and abroad.
I asked him an interview.
1) When and where were you born?
I was born in the 1950’s in Surrey, just west of London.
2) What is your first memory of listening to the radio?
In the 1960s, I remember 'Big L' (Radio London) booming out from the car
radio. The music was exciting, the DJs were entertaining - it was a great
introduction to radio. I also remember listening to Radio Luxembourg in the
evenings, playing songs that other stations did not. Then there was the
excitement of BBC Radio 1 launching in 1967 to fill the gap after Big L had
closed down. It was a time of great changes in radio, which made the
experience inspiring for young people.
3) When did you start listening to the radio and why did you like it?
I listened to radio for the music. I had always loved pop music and radio
provided the opportunity to hear all sorts of new artists, new songs and new
styles of music. We had a tape recorder that we used to record our favourite
songs from the radio so that we could listen to them whenever we wanted.
Radio provided my music education, for which I am eternally grateful.
4) When did you start working for a radio?
My first involvement in radio was in the early 1970s, when I worked for AM weekend pirate radio stations in London, including Radio Concord, London Weekend Radio, Skyport Radio and Swinging Radio England. I initially answered the listener phone line and then presented programmes, on my own and also with my friend Jerry.

5) In your book "DAB digital radio -licensed to fail" you seem very
skeptic about the success of digital radio in UK; do you think there's
no hope for digital radio in the foreseeable future?
I believe that digital radio has a great future. The problem in the UK is
specifically about the DAB platform and the way it has been implemented. The
technological developments that have enabled radio to be distributed all
around the world, and to a dazzling range of connected devices, are
absolutely incredible for the radio medium. Unfortunately, DAB had been
marketed in the UK as a means for existing radio broadcasters to maintain
their control over the radio market. Increasingly, consumers have been
disinterested in DAB radio, as demonstrated by declining sales of DAB
receiver hardware in the UK. The outcome is that DAB will not succeed as a
replacement for existing FM/AM broadcast radio. But digital radio as a whole
has a positive future.
6) What is your opinion about DRM (Digital Radio Mondiale)? and DRM+?
It seems that DRM will be useful for longer range radio broadcasts, though we are in a period when shortwave is being used less and less by international broadcasters. Those places that are most reliant on shortwave (Africa, Latin America, etc) are likely to have the slowest take-up of new, relatively expensive hardware technologies such as DRM. As a result, it is hard to see DRM as anything more than a supplemental technology to analogue reception. Just because a technology is inherently better does not guarantee its take-up (viz Betamax and digital compact cassettes).
7) As a paradox, could we say that in Italy digital radio has more chances for success than in the UK because Italy has basically skipped DAB and it's going straight to DAB+?
The biggest challenge for implementing DAB is the economics of radio, rather than whether the codec is DAB or DAB+. There are at least three economic issues. Firstly, consumers update their radio hardware infrequently, requiring simulcasting on analogue and DAB for at least 10, maybe 20, years, which at least doubles a station’s transmission costs for a long period. Secondly, advertisers use radio because it is a ‘mass’ medium, so they have no interest in using DAB until it reaches millions of people, which results in no revenues from the DAB platform for the first 10, maybe 20, years. Thirdly, consumers already have a large choice (compared to TV) of analogue stations on AM/FM, so it is hard to find ‘new’ radio content that will motivate them sufficiently in large numbers to buy new DAB radios. These economic issues make it unlikely that DAB+ will have any more success than DAB.
8) Are you sure that there is future for "radio on radio spectrum" or
is it just a waste of time because internet-radio will rule above any
other alternative systems?
I think that broadcast radio (FM/AM) still has a future because reception is
so robust, as a result of 50+ years of investment in the extensive
transmission systems. I can stand in the middle of nowhere and still pick up
broadcast radio. Internet radio cannot match that level of universality at
present. Eventually, the IP platform may be able to compete head-on with the
broadcast platform, but we are not at that stage yet. For the next few
years, internet-delivered radio is a very useful supplemental platform to
broadcast radio that offers the consumer a much wider choice of content and
the ability to timeshift programmes. It is important to remember that, when
local or national emergencies happen, it is broadcast radio that citizens
turn to for information, because electrical power cuts bring IP networks
(and even television) to a standstill. A single transmitter on long wave can
cover almost the whole UK - that is a difficult distribution system to beat!
9) Since your youth, you've beeing seeing huge change of radio-set (a topic that it's rarely discussed), from analog radio-set to digital display (including RDS) of today sets. What's your opinion about it? Is there any evolution that you'd like to see in the near future?
At the end of the day, it is content that drives people to listen to the radio. All the technology does is make it possible to deliver that content to them. Some of the most popular radio stations have had less than perfect reception experiences – Radio Luxembourg on AM, Laser 558 on AM, Atlantic 252 on long wave, and all the FM pirate stations – but consumers will sacrifice quality for content any day. This is why people are happy to listen to low-fi mp3’s on their mobile phones. I think this phenomenon will remain. The biggest difference between then and now is the huge choice of stations offered by IP. When I grew up, there were never more than a handful of radio stations to choose from. Now, there are thousands. The challenge now is to enable consumers to find something of interest to them and to help them navigate their way around the global menu of radio available to them. We need a Google for radio that will deliver search results to a listener, however arcane their request for a radio station to match their tastes.

Interview with Gary Frost about history of FM

Gary Lewis Frost was born in Idaho (USA) and studied to be an engineer at California State University--Fullerton; later, he received a Ph.D. in history at the University of North Carolina--Chapel Hill.
The Johns Hopkins University Press published his book called "Early FM Radio: Incremental technology in Twentieth-Century America". I won't pretend i read his book (i haven't but i'm willing to) but i asked him few questions about it.
1) How would you describe the main point of the book "Early FM Radio: Incremental technology in Twentieth-Century America" ?
A: Most readers, I hope, will credit the book principally for correcting errors in the traditional history of FM radio's origins. For more than half a century, historians have claimed that practical broadcast FM technology sprang from the mind of one man, Edwin Howard Armstrong, during his solitary quest to conquer static noise. They have also claimed that by the time Armstrong patented his system in 1933, only he had not abandoned frequency modulation as unworkable. Early FM Radio debunks these and several other false claims.
2) If the commonly accepted history of FM radio is wrong, why did this account last for more than 50 years?
A: For one thing, any serious historian who desired to take a fresh look at early FM really had to understand how radio technology works. I'm not the first person to possess the technical knowledge required to write a book about FM radio's origins, but historians like me have probably comprised a very small group, perhaps a handful of individuals. Second, the most important archive of primary sources, the collection of Armstrong's papers (stored at Columbia University, New York), has been especially difficult to research. It's several hundred boxes of sketchily-indexed papers and microfilm, and only recently have Columbia's archivists had the funding to begin cataloging the collection adequately.
Finally, ever since 1956, the year Lawrence Lessing introduced the traditional history of FM in his engaging biography of Edwin Howard Armstrong, those who might have aspired to overturn that history have encountered a psychological obstacle. Lessing played on his readers' sympathies by describing Armstrong as a man of singular genius and moral integrity, who after inventing FM radio in 1933 courageously fought the heartless mega-corporation (i.e., RCA) that attempted to suppress his creation. Later, RCA tried to rob him of credit for inventing FM, and he spent a fortune defending his patents. Lessing also implied that Armstrong's suicide during the patent trials amounted to an act of martyrdom in defense of individualism, anti-corporatism, and technological progress. If my own experience is representative, it can be emotionally difficult even to think about questioning this story.
3) When was your interest for radio born? and How?
A: Although I listened to shortwave radio when I was a boy, and later worked as an electronic engineer, my interest in the history of radio surfaced only after I entered the humanities. I was seeking a historical topic for my master's thesis, and my graduate school advisor suggested early radio. I ended up writing about Reginald Fessenden, the Canadian who first transmitted the human voice using something like amplitude modulation in 1900. When it came time to choose a topic for my doctoral dissertation, I was open to almost anything, but I committed to FM radio quickly. Only a few hours of research revealed that although without exception every book that examined FM radio's history derived from Lessing's Armstrong biography, that book failed to provide citations, and contained several serious contradictions and omissions. Originally, I set out only to resolve those contradictions, and to fill in gaps about the actual technology. I never imagined that I'd eventually publish a book arguing that Lessing was wrong about so many things.
4) In developed countries they are trying to start digital modulations (mostly Ibiquity in US and DAB/DAB+ in Europe) but the listeners don't seem to be happy about it; what's your opinion about the transition towards digital radio?
I'm not familiar with the specific problems of Ibiquity and DAB/DAB+ that you mention, so I'll venture to guess why some listeners might express dissatisfaction with digital audio in general. The history of FM radio suggests both technical and nontechnical reasons. Perhaps somewhere along the signal path--from studio microphone to the listener's speakers--shortcuts have been taken that degrade audio fidelity. A wobbly sampling frequency or some other distorting factor created by an inferior analog-to-digital converter for example, will cause distortions on playback. So will the misuse of digital audio technology. Lowering the sampling frequency narrows the audio bandwidth. An excessively “lossy” method of conversion discards too much data to preserve fidelity. Again, I'm making these guesses solely on what the history of FM teaches us. In 1940 RCA proposed that the Federal Communication Commission establish an FM broadcast service with a maximum allowed frequency swing of 100 Khz. We should be thankful that the commission rejected that proposal and adopted a standard of 150 Khz instead. Otherwise, FM radio today would not sound as good as it does.
I want to add that by broadening our perspective beyond just the hardware, we'll almost always find non-technical factors that influence technical choices. Audio engineers and listeners typically have limited budgets, which motivate them to use cheaper (and thus too often inferior) apparatus. And then there's the sometimes bewildering factor of listener psychology. During my research I discovered many people in the 1940s and 1950s who expressed a preference for AM radio over FM. Their explanations resemble those of many people today who object to digital audio on principle: FM, they protested, sounded sterile and cold, and even “ghastly in its realism.” I don't know if this kind of thinking accounts for much listener dissatisfaction with Ibiquity and DAB/DAB+ today, but I've heard many people who have nothing but entirely subjective reasons to back their assertions that analog audio always sounds better than digital sound.

Interview with Pure
PURE (former name was PURE DIGITAL) is a british manufacturer that makes digital tuners. Colin Crawford (PURE's director of marketing) answered some questions.
1) When was Pure founded? and by whom?
PURE was founded in 2002 and is a division of Imagination Technologies, founded in 1986.
2) Beside the "propaganda" of engineers and lobbysts, what's your view of digital radio? Do you think it will be able to replace FM (in near future) or will it be always work-in-progress situation?
We believe strongly that the idea of analogue radio in a digital world is a nonsense. For radio to remain relevant, it must go digital and visionary markets such as the UK, Switzerland, Denmark, Germany, Italy, France and Australia are making that happen already.
3) Pure doesn't sell products with DRM (Digital Radio Mondiale). Why?
Because there is no consumer demand.
4) Might DRM+ change this choice?
We remain to be convinced but we will keep monitoring any opportunities in this area.
5) Do you think that a unique european standard (like DVB-T for television) will help strongly the manufacturers?
The DAB family of standards is already a unique European standard and the standardisation of profiles by WorldDMB, EBU and DIGITALEUROPE brought the digital radio market together for the first time and has already revitalised the industry for manufacturers.
6) Are you sure that there is future for "radio on radio spectrum" or is it just a waste of time because internet-radio will rule above any other alternative systems?
PURE is a strong believer in hybrid radio systems that combine broadcast radio content with internet connectivity. This provides a perfect solution whereby mainstream listening happens efficiently by broadcast and niche content and interactivity can be delivered over the internet. The idea that the internet could cope with the hundred of millions of hours of radio listening is preposterous.
7) Which radio station do you listen to, during your spare time?
I am a profligate radio listener spending nearly all my time on broadcast radio with a good mix of BBC and national UK commercial stations.

Interview with Revo - part 2 of 2
(interview with Revo - part 1 of 2; 4 march 2010)
we have the second part.
6) What does Revo think about DRM (Digital Radio Mondiale)?
The Digital Britain White Paper set out the Government’s vision for a radio industry in a digital world and the mechanisms needed to deliver it. To date over 10 million digital radio receivers have been sold and around 20% of all radio listening is via a digital platform. Listeners are clearly being attracted by digital-only services, including the BBC’s digital-only stations. We believe there is already significant momentum towards digital radio take-up and the decision for Government is not whether digital radio will replace analogue, but to ensure that any transition to digital is delivered in a coordinated way which best reflects the needs and expectations of listeners. However, we have been clear that this process will be market-led and will only consider setting a date for digital radio switchover once 50% or more of all radio listening is to digital.
The Government recognises that we must ensure the environmental impact of any significant analogue radio disposal is minimised through a responsible disposal and recycling strategy. Any waste electrical equipment produced as a result of Digital Radio Upgrade will be disposed of subject to the requirements of the EU Waste Electrical and Electronic Equipment (WEEE) Directive. The Government is working with manufacturers to consider the implementation of a ‘set-top box’ solution for analogue radio which would allow existing analogue radios sets to receive DAB.
We acknowledge that some parts of the UK currently have access to overseas analogue radio services. Digital radio, via the internet, will in fact increase the opportunity for listeners to access overseas radio stations not just from neighbouring countries, but from around the world.

Interview with a european commissioner - part 2
second part of an interview with (a member of staff of) european commissioner about "Information society and media"
2- The main difference between digital tv and digital radio is that digital tv (in Europe) has one standard (DVB-T), while digital radio has a lot of standards (DAB, DAB+, DRM, DRM+,IBOC,etc). Do you think that this is the reason behind the failure of the success of digital radio in Europe? Or should we blame the broadcasters?
Given that cable, satellite and terrestrial transmission all require different modulation schemes, there are actually different standards for digital TV, even if the Digital Video Broadcasting (DVB) Group has made conversion between them very easy. Within the DVB-T standard, technological progress means that a more modern compression standard - MPEG4-AVC - is now being used alongside the older MPEG2 system. A new and more efficient standard called DVB-T2 is also entering the market in order to facilitate HDTV transmissions in scarce terrestrial spectrum. It is a myth therefore that there is a single standard for digital television. We have a family of co-existing standards, which evolve in the light of technological possibilities and market needs. The situation is not so different in digital radio.
So far, digital radio has been launched successfully in a number of EU Member States.
Radio is an important part of the cultural landscape in Europe and can be delivered over a huge variety of different platforms. Besides dedicated digital terrestrial transmission for which different standards exist, radio services are also transmitted over the internet, over digital terrestrial and mobile TV platforms, via cable and satellite and over analogue terrestrial FM and AM networks.
The most common digital terrestrial radio standard in the EU is Digital Audio Broadcasting (DAB). The United Kingdom is by far the most advanced country in the EU in terms of penetration with digital radio using this standard. By mid 2008, 6.8 million digital radios had been sold in the United Kingdom (and 1 million in Denmark).. DAB has also been implemented in Belgium, Germany, Denmark, Spain, Luxemburg, Netherlands, Portugal and Sweden.
Freeing up spectrum for new wireless applications and innovative broadcast services drives EU policy on terrestrial TV switchover. The current DAB standard for digital radio transmission does not provide a significant increase in the efficient use of spectrum over (analogue) FM radio. That is why so far there has been no spectrum efficiency argument for switching off analogue terrestrial radio.
Now, established market players and new entrants have a second generation of digital terrestrial radio broadcast standards available which use spectrum more efficiently. These standards facilitate innovation and interoperability. At the same time co-ordination around common solutions has become more complex.
France will introduce a second generation standard for digital radio, Digital Multimedia Broadcasting (DMB). Launch is planned for December 2009 in Paris, Nice and Marseille. In the Netherlands there are also plans to launch DMB radio, in combination with DMB mobile TV services before the end of the year in The Hague.
Malta has launched DAB+ services in 2008.
16 Member States have not yet introduced digital terrestrial DAB-based radio. All Member States still heavily rely on analogue FM and AM radio since receivers are cheap and almost omnipresent.
The WorldDMB industry group has developed receiver specifications which would integrate the first generation digital radio standard DAB and the second generation standards DAB+ and DMB in one receiver, thanks to the availability of more powerful integrated circuits (chips). These receivers facilitate the upgrade from DAB to DAB+ and DMB in a Member State and would allow the reception of digital radio services in foreign countries if one of the three standards is used.
This demonstrates the ability of the market to come up with solutions where different broadcast standards are used. Consumers and broadcasters are served best if the selection of radio transmission techniques is left to market forces, industry co-operation and well co-ordinated national policy initiatives in which all players are carefully consulted.
The Commission will continue to monitor technological and market developments closely and to discuss digital radio issues with Member States and industry.
3 - Do you think that Europe should help the transition to digital radio with public funds or leave it to the interaction among broadcasters, manufacturers and listeners?
Because of the subsidiarity principle, this question would have to be answered at Member State level. For digital TV switchover, there have been no subsidies at EU level.
