Mike Terry wrote: Monday, 25 October 2004 "Digital short-wave will revolutionise cross-border broadcasts and will initiate a world-wide renaissance of radio". This was the opinion of the Director General of Deutsche Welle, Mr Erik Bettermann, during a panel discussion at Münchner Medientage. Bettermann, the head of the German international broadcaster - and instigator of the event - was not the only one to present an optimistic prediction of a "Digital Global Radio" development: The other panel specialists also emphasised the advantages of digitalisation in the so-called AM range, i.e. short-, medium- and long-wave. The discussion was chaired by Peter Senger, Director of Distribution at Deutsche Welle and Chairman of the Digital Radio Mondiale (DRM) Consortium; and next to Erik Bettermann, BBC representative Mike Cronk, Dan D'Aversa of RTL Group and Phil Laven of the European Broadcasting Union (EBU) were also participating in the debate. Senger outlined the advantages of digital short-wave as follows: The world-wide accepted DRM standard provided an excellent audio-quality comparable to FM. In addition, the search for frequencies was obsolete, as the station identification tuned in to the designated frequency and automatically switched to the best one. In parallel, it allows for the sending of accompanying programme information such as text messages. "On top of everything, digital transmission technology saves a lot of energy and costs compared to the analogue one", Senger said. This would open up enormous opportunities, especially for international broadcasters. For several years, DW - like many other broadcasters - has noted that listeners migrated from short-wave to FM or other new distribution channels in digital quality, said Bettermann. Deutsche Welle had to stay abreast of these changes. "According to test transmissions being operated by Deutsche Welle, we anticipate large area coverage in almost FM quality without interference such as jitters, induced power-noise or fading", the General Director stated. At the same time, not only stationery indoor reception, but also mobile reception in cars and with small portable devices is possible...(snip)..... Mike Cronk stated that the BBC had invested heavily in DRM and that they were now developing "a detailed strategy for its initial deployment, probably into Europe, in 2005". According to Cronk, DRM offered the unique combination of wide area short-wave coverage and FM usability and quality. As a consequence of using this digital medium, continuous direct delivery to the audience avoiding "political or other regulatory obstacles" will be possible...(snip)....

SW broadcasting is funded so that listeners can hear programs, not for the benefit of amateur DXers. DRM lets the intended listeners actually hear those programs clearly, and tune them in easily. It sounds like you don't like it cause it sounds like noise on your (probably highly expensive) set-up, and you like the tuning process to be as difficult as possible. Yes, without co-ordination there may be interefernce problems during the transmition period, but the sooner the world goes DRM the better international radio broadcastings prospects IMHO. No two ways about it, DRM = QRM... there is no way around it. If you want crystal clear fidelity I suggest you get yourself a nice FM set. All I can say is die DRM, die. dxAce Michigan USA |

DRM is great IMO. I get very good stereo signals on SW from DW and RTL etc.

Perhaps you will tell us how the intended audiences of most shortwave programming will be able to obtain these DRM receivers? Since most of these broadcasts are intended for audiences outside their own countries, and for other than their own expatriots (e.g. third world or oppressed populations), those audiences are not likely to be able to afford (even if they could obtain) such radios. Ordinary AM shortwave could be received with nothing more than a few meters of wire, a variable capacitor (and even a fixed one will work, depending upon design), a diode and an earphone. Reception of DRM requires technology that is not available to much of the world. |

Precisely. The simple fact is, the slick salesmen haven't found a way to get around the laws of physics, quite yet. They have, however, found a great new "income channel," an income channel which allows the "account executives" to "maximize ROI," or some such.

"Colin" wrote in message ... Hmmm - just like IBOC is 'QRM' for FM reception? IBOC sure is QRM for AM reception! SW broadcasting is funded so that listeners can hear programs, not for the benefit of amateur DXers. So why have so many countries been defunding international broadcasting? Could it be they think international broadcasting is a waste of money? Why would clearer signals make it less of a waste? If the programming is worth hearing, the listener will put up with occasional distortion and fading. DRM lets the intended listeners actually hear those programs clearly, and tune them in easily. It sounds like you don't like it cause it sounds like noise on your (probably highly expensive) set-up, and you like the tuning process to be as difficult as possible. International broadcating is boring, and bored listeners are tuning out. DRM won't fix that. The internet is a much better source for news. End time preachers and conspiranoics are much more fun to listen to.

The name escapes me at the moment, but there is one service that covers most of the (non-US) world in several regions. I reiterate however, that people in third world and oppressive countries will not have access/not be able to afford the receivers for either this or DRM. |

"Aztech" wrote in message ... Satellite radio does every thing DRM promises. ... if you're in the US, which doesn't include 95% of the world. Az. I think there's direct broadcast satellites serving areas outside the US. The cost of satellite receivers is a real concern, but it's also a concern for DRM. Anyway, the international broadcasters could get together and put up a few direct broadcast satellites, if they really wanted to make the investment. DRM doesn't really get around shortwave's reliability problems. The shortwave utility bands used to be filled with digital signals 25 years ago. These signals were highly reliable. If there was any propagation at all, they would get the message through. Despite having high power shortwave transmitters, selective and sensitive receivers, highly directional antennas, sometimes the message didn't get through. There's now only maybe 10% the utility traffic there once was. The balance, plus the whatever expansion there was, went to satellites. The utility stations wanted 100% reliable communication. They ditched SW. Frank Dresser |
