KTWR on 7500 kHz, DRM to Japan (B19)

KTWR to Japan logged for 14 minutes from 1228-1242 UTC. Good tonight. Max. 23,60 dB SNR and 99,92% decoded audio. Meta Data: 10,26 kbps, EEP, aac, Mono, English, Religion, Guam, ID:1001. Technical: Mode B/10, 2s, 4/16 QAM, P:0/0, A:1/D:1 Timestamp: Yes. MOT Slide Show: I received three slides using the DRM Software Radio 2.0.38 because the MOT Slide Show did not work with DReaM V 2.1.1.

Later when I played back the 12 kHz IF mp3 file from my Newstar DR-111 I got a total of 10 slides. One of the slides was a QSL Card for the transmission on the 7th Nov. 2019. Nice!

I used two receivers, the FRG-7700 and the DR-111. The DR-111 was sitting on the desk beside my PC using its telescopic antenna and powered by a 5V GP Power Bank 5200. The broadcast was in Japanese tonight.

1. KTWR to Japan logged with FRG-7700 for 14 minutes from 1228-1242 UTC. Good tonight. Max. 17,75 dB SNR and 91,18% decoded audio (99,57% from 1233 UTC). Meta Data: 10,72kbps, EEP, aac, Mono, Chinese (Mandarin) [!], Religion, Guam, ID:1003. Technical: Mode B/10, 2s, 4/16 QAM, P:0/0, A:1/D:1 Timestamp: Yes. There were Text Messages in Japanese in the Message window in DReaM V 2.1.1. The Audio Spectrum was limited to 4000 Hz.

2. KTWR to Japan logged with DR-111 for 12 minutes from 1229-1241 UTC. Max. 17,00 dB SNR and 91,95% decoded audio. There were Text Messages in in the the display of the Newstar DR-111, but only "?" instead of Japanese as the DR-111 cannot display Unicode characters.
