World Radio TV Handbook or WRTH is now in its 75th year. It is the most accurate and complete guide to the world of radio on LW, MW, SW and FM, available in any form.
It is divided into the following sections (for information on using WRTH please see our pdf on How to Use WRTH):
Features – This section is in full colour and contains reviews of receivers and ancillary equipment, articles on topical issues such as digital radio, interviews with broadcasters, reception conditions, colour maps showing the location of SW transmitters, and other topics of interest to Listeners and DXers.
National Radio – This section covers the world’s domestic radio services. The listings are by country and include all stations broadcasting on LW, MW and SW, and most stations broadcasting on FM, together with contact details.
International Radio – Full details of all broadcasters transmitting internationally are given in this section and are listed by country. The schedules shown are the ‘B’ or ‘winter’ SW frequencies as supplied by the broadcasters and confirmed by monitoring, together with any LW or MW frequencies used. It also contains a sub-section showing Clandestine and Other Target Broadcasters arranged by target country. The ‘A’ or ‘summer’ schedules, along with updates to broadcaster details, are available as a pdf download from this website in May each year. Please note that International broadcast SW frequencies change twice a year. The ‘B’ season comes into effect at the end of October each year and the ‘A’ season at the end of March. It typically takes 4-6 weeks after the start of the season for the broadcasters to settle on the final frequencies they will use, although changes do continue to be made. We monitor all the frequencies and changes before releasing our information.
Frequency Lists – This section contains MW frequency lists grouped by frequency within regions, lists of all international and domestic SW broadcasts in frequency order, and international SW broadcasts in English, French, German, Portuguese and Spanish, and DRM transmissions shown by UTC.
Television – The TV section has details of the main terrestrial national broadcasters, large regional networks, and some local stations, arranged alphabetically by country.
Reference – This section has tables and listings of: International and Domestic Transmitter sites, Standard Time and Frequency Transmissions, DX Club information, International Organisations, and other essential information.
