Dual Audio Services Christmas Night

 On 25 December KTWR will broadcast our regular DRM programs to China at 10:57 UTC and Japan at 12:00 UTC with two audio services.  The Chinese program will be available in either Mandarin or Cantonese and the Japanese program in either Japanese or Korean.  Both will be on 9910 kHz.  To accommodate both channels we will be using 64QAM modulation rather than our usual 16QAM.  This will raise the threshold SNR for reception by about 4dB.  If you have difficultly receiving the signal, please use your best antenna and eliminate local noise sources (florescent lights, PC power adapters, ...).  The 11:29 UTC Japanese program, The Word Today, will be broadcast in the single audio/ 16QAM format.
