AM Radio: No Longer Practical?
Kenji Rikitake

I’m not saying you are wearing, but could DRM technology breath new life into the frequency band currently used by AM transmission.

While signal noise is bad for local and national AM reception, it has effectively killed Long Wave (153–279khz) and short wave (2.0 -26MHz) international broadcasting. While we (in the West) think now of international broadcasting as a vanity project, it has had, and could still have had a use in defending political rights by allowing dissenting views to be heard in otherwise restricted areas.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
