Larry Van Horn, New Products Editor 2013 World Radio TV Handbook The New Year brings many things to radio hobbyists, including new goals for a successful DX season. Ultimately, listeners always welcome the new edition of World Radio TV Handbook (WRTH), a stalwart in the industry for 67 years. This year’s edition is no exception, as WRTH continues their reputation as a comprehensive reference book for broadcast radio hobbyists. The 2013 edition begins with a receiver review on the Newstar DR 111. This small and capable SDR (software-defined radio) continues to gain interest, and review leaves little doubt that high performance is now available at very affordable prices. The world of Internet radio continues to expand and WRTH reviews the best of the year in this category, the Roberts Stream 83i. This year’s WRTH reviews also include a look back at classic DSP receivers. The features section begins with Children’s Radio Foundation (CRF), a non-profit organization in Cape Town. CRF provides tools and skills to make the voices of African youths, an outlet to tell their stories. With the absence of broadcasting in the Netherlands Antilles, and unfortunately a decrease in tropical band stations, resourceful DXers have shifted to medium wave and FM transmissions. Listening on Curaçao, by DXer Max van Arnhem, reflects on the political and radio changes in the small island of Curaçao. Digital Update revises the annual round-up of what has occurred in the world of digital radio and TV during last year. Freelance writer Hans Johnson explains why newly-founded clandestine station Khmer Post Radio has chosen to send their message via shortwave radio. George Jacobs updates his annual HF Broadcasting Reception Conditions Expected during 2013, with a prediction of improved grade of service for the worldwide HF listening audience. The national radio section of the WRTH includes domestic radio stations which broadcast to a national listening audience on medium wave, shortwave and FM. Listings are arranged by country and include frequencies, transmitters, power, contact information and website if applicable. The international radio section contains stations broadcasting to an international audience. Similar to the latter, this section includes frequencies, transmitters, power, contact information and website. Clandestine and other target broadcasts are stations broadcasting politically motivated programming, or those targeted at zones of local or regional conflicts. A one-page listing cross reference of religious broadcasters closes this section. The by-frequency list covers medium wave, shortwave, DRM, and a by-hour listing of multilingual international and DRM broadcasters, plus an update on terrestrial television. Closing out this year’s edition is an extensive reference section of global transmitting sites, radio clubs, standard time and frequency stations, and selected Internet Resources.
