Overview:

This handbook explains how to tune in shortwave radio broadcasts or other global communications in your web browser, using WebSDR technology. If AM talk radio in your town gets you down, try some music and features from some far away exotic place. Tune in new sounds via WebSDR! Curious about shortwave listening or ham radio? These top notch receivers are a great way to discover the science and theory behind today's advanced communications.

WebSDRs are a type of Software Defined Radio which picks up radio signals, converts them to digital format, and can stream them to your computer, tablet or smartphone for listening, wherever you are in the world. You don't even need to have your own radio or antenna. Tune in distant stations, heard on high performance receivers on the other side of the world.

Hundreds of WebSDRs are online, operated by volunteer radio amateurs and engineers. They are free to use, and high performance, but can be tricky technology. They are es[ecially useful technology for people who live in noisy environments, with poor reception, high rise apartment residents, and people who live far away from their favorite stations. WebSDRs are also useful for breaking out of censored media bubbles, where local news is censored and foreign broadcasts jammed.

This book is packed with operating tips and good know-how for shortwave listening on the network of WebSDRs.
