World Radio Tv Handbook 2007 [antikvár]

FEATURES Editorial Editorial NEW WAVES Welcome to the 61 st edition of WRTH. In this new edition, as well as providing our impressive range of data on stations and transmissions, we continue to explore the increasingly digital future of broadcasting. We review three software-defined receivers and it is noteworthy that this is the first occasion on which these have outnumbered conventional receivers in our tests. We also bring you the latest news from the front line of the digital revolution in our regular Digital Update. Last year we attempted to look into the future of world broadcasting with the help of some of the leading figures in radio. These interviews were greeted with such enthusiasm that we have conducted another series for this edition. We hope that you will be as fascinated by the insights they provide as we were. WRC-07 Many of the issues they address will be the subject of intensive discussion at this year's World Radio Conference, not least the availability and use of HF spectrum. The responses to an ITU questionnaire sent to EBU members showed that over the next ten years 55% of those members expect to increase their requirement for HF spectrum, with only 8% anticipating a reduced use. From this and other data, the ITU concludes that, "HF spectrum occupancy is unlikely to decrease in the next 10 to 15 years [although] DRM will progressively replace analogue transmissions". When this is read in conjunction with a detailed long-period ITU study which suggests that up to 750kHz of additional spectrum is required in the 4-10MHz band, it bears out our frequently stated view that HF broadcasting is indeed in good health. We will be interested to hear more news on the replacement of analogue transmisions by DRM. INTERNET One of the most obvious manifestations of the digital age is the internet. It has been blamed for the demise of many conventional DX clubs and has certainly provided another outlet for state-sponsored HF broadcasting. But it is also building a world radio community and promoting, as our founder O. Lund Johansen stated in the 1953 edition of How to Listen to the World, " a better understanding between the peoples of the World" CONTRIBUTORS This handbook could not be produced, as we often state, were it not for the hard work of our worldwide team of contributors. We were very sorry this year when Tore Larsson, who has been a dedicated Contributing Editor for many years, decided to lay down his editorial pen, but we are delighted to welcome Christer Brunstrom who has taken over the editing of the Central American countries. Paul Ormandy has similarly passed on the baton for updating New Zealand and the Pacific to David Ricquish, who also provides a fascinating history of broadcasting in the Pacific in this edition. Last, but by no means least, we would like to pay tribute to Bengt Ericson who has also relinquished many of his editorial duties. Bengt has been involved with WRTH for almost 50 years and has provided excellent counsel and valuable support to the current editorial team. His inclusion as our Featured Contributor on the following pages is long overdue. WEB UPDATE Our publication of updates on the WRTH websWe has once again been enthusiastically received and we intend to continue the practice for the B06 and A07 seasons. We will also continue to include updates to the National Radio section in our new WRTHmonitor page. Readers have made extensive use of the new feedback page and we welcome all your comments.
