Season Two of On the Media’s Peabody-winning series The Divided Dial is the untold story of shortwave radio: the way-less-listened to but way-farther-reaching cousin of AM and FM radio. The medium was once heralded as a utopian, international, and instantaneous mass communication tool — a sort of internet-before-the-internet. But like the internet, it also took a turn for the chaotic. And like AM and FM talk radio, it also went hard to the right, with extremists and cults still finding a home on the shortwaves

EPISODE 1:

You know AM and FM radio. But did you know that there is a whole other world of radio surrounding us at all times? It’s called shortwave — and, thanks to a quirk of science that lets broadcasters bounce radio waves off of the ionosphere, it can reach thousands of miles, penetrating rough terrain and geopolitical boundaries. How did this instantaneous, global, mass communication tool — a sort of internet-before-the-internet — go from a utopian experiment in international connection to a hardened tool of information warfare and propaganda?

The Divided Dial was supported in part by a grant from the Fund for Investigative Journalism.
