KTWR is about to start regular DRM broadcasts to four different areas. There will be broadcasts one day per week to each of four areas starting 5 August 2019. They will be working with the content server parameters to come up with the best compromise settings for each area. Each week will have different settings. KTWR will really appreciate your feedback for as many weeks as possible. Your assistance will ultimately help give your fellow listeners the best possible reception in the long run. For now, all programs will be in English.
The schedule will be as follows, starting the week of 5 August through the end of the A19 broadcast season:
Day Freq Time Region Power
Monday 11580kHz 1215-1245 UTC South Asia 90kW
Tuesday 11995kHz 1026-1056 UTC ANZ/South Pacific 50kW
