Message from Steve Brunson, KTWR Chief Engineer, Agana, Guam....

Dear DRM Monitors,

One of our three transmitters is currently down. We won’t be able to fit our DRM test to China into the schedule for tonight, 25 September. It’s possible that we won’t be ready for our DRM broadcast to Japan tomorrow night, 26 September. We’ll send an update when there’s news to report.

Thank you for your interest and your great data!
