I was bored this week and decided, why not make a Bosai Musen map for the outlying Islands of Toyko? So I did & here is the result: a map packed with technical information, frequency ranges & modulation types. This mapping style is still a trial run for me, as Hokkaido didn't turn out great ...

Are you able to do a map of Texas please? The map is amazing by the way :D Thanks! I'm glad you like the map! I don't have any plans to make a Texas Siren Map, but it could be a future project. If you have any municipalities you're interested in, feel free to drop the name & I'll look into it.

I was searching through YouTube for videos about Japan's Dam Warning Systems. I then came across this big red motor siren. I was wondering if anybody here on ARS knew anything about this siren. To clarify, this is not a Toshiba product. Toshiba manufactures control equipment for loudspeaker substati...

Neat map! I like the concept of using pins, however. This is just a suggestion: use regular pins instead of icons. Once you start hitting the 10K+ mark, it could start lagging quite a bit. Also don't get confused with Fire Radio, they use similar equipment to the stuff used on the Slave/Substations ...
