This headline sounds a lot worse than the actual news. Radio Japan broadcasts a single half hour program per day to North America by short wave. It's on at 0500 UTC for the western half of the continent, and repeated at 1200 on a different beam slew for the eastern half.
The Disco Palace is on more than that, and THEY are in DRM.
These two short transmissions come from the TDF site in French Guyana that was reported on yesterday in this blog. As we know, it is closing April 1, for economic reasons. Obviously, all services contracting for time on the site's 5 transmitters must either drop their NA beams or look for increasingly scarce alternatives.
