On the media's "The divided dial" series about shortwave

A friend alerted me to an interesting series of programs about shortwave from WNYC Studios.

"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".

First I've heard of The Shortwave Modernisation Coalition which proposes to use shortwave for high speed trading.

I think there is a role for shortwave broadcasting but today I think it should broadcast a hard to jam, easy to receive digital data format.
