Dual Tone Waves/MadahCom Tsunami Sirens sounding in Okinawa

[echo1030]

Probably the best recording I’ve ever heard of an 850/1020hz Waves. They are heard at around 1:30 in the video. As many of you are aware, a large earthquake in Taiwan triggered Tsunami warnings across the Asia Pacific rim. Obviously the video is not mine, but it’s definitely worth sharing with the siren community!

There's actually a high likelihood that the siren you are hearing that randomly cuts from voice to tone is a Whelen. They have a number of them on the base with the WAVES sirens. They are on WAVES RTUs. The WAVES sirens will actually wind up when activated.
