DRM on 12055kHz is Coming Soon

Happy new year everyone.

The 12055kHz broadcast to South Asia will start the first week of January. This will be Tues-Fri at 1515-1545UTC. The God Centered Life program will be in English. It is expected to last at least until the middle of the year. 

KTWR will be beaming this at 90kW at 285 degrees. It will be interesting to see how coverage differs from the 15390kHz Sunday DRM broadcast that is at the same power and azimuth. Reception reports for both broadcasts would be helpful.

 We are planning special DRM broadcasts for Christmas Eve, 24 December 2022.  These will be during our regular Saturday evening DRM broadcast slots to China, 12040 kHz at 1100 UTC, and Japan, 9910 kHz at 1200 UTC.  We will be airing two audio services for each program, Mandarin and Cantonese at 1100 and Japanese and Korean at 1200.  These will be accompanied with slides.  64QAM modulation will be needed to support the higher data rate.  This will require an SNR at the receiver of about 17dB vice the 13dB threshold for 16QAM.  We hope you'll be available to listen and that you receive a strong signal!

The weekly Japanese language program, Every Man a Warrior, will still be aired at its usual time, 1130 UTC, in 16QAM format.
