1639z recheck: NHK Radio 2 went off-air, and NHK World-Japan switched to some programming - with ticker still rolling. Have they already cleared all #tsunami advisories?
Meanwhile, emergency broadcast still carries on on NHK General TV, via 360p emergency stream https://newssimul-stream.nhk.jp/hls/live/2010561/nhknewssimul/master-512k.m3u8
and on NHK World Premium https://cdn.skygo.mn/live/disk1/NHK_World_Premium/HLSv3-FTA/NHK_World_Premium.m3u8 #tsunami
This is how NHK Radio 2 went off, via JP1ODJ Saitama
#KiwiSDR tuned to 873 kHz rather than local 693. Carrier still seems to be on there, although 828 was off at that moment. #mediumwave #tsunami
