The World Radio TV Handbook, also known as WRTH, is a comprehensive directory of global broadcasting. It contains most radio stations with FM or AM transmitters as well as TV stations, published yearly. The focus is on frequencies, television channels and effective transmitter powers. The listings of international broadcasting and shortwave radio contain schedules. For major broadcasters, addresses, telephone numbers and e-mail are given.
Started in 1947, it became one of the most important references for the DXing community, hobbyists trying to receive distant radio broadcasting. The German based Radio Data Center (RDC) which links DXing and professional data services has published the WRTH since 2022.[1] including an app and an online version.
