I also noticed that in the first video in this thread, the Whelen was activated before the other sirens were. The Whelen could have been a privately owned siren, or it may have had to have been activated independently, because there is sometimes a conflict with Whelens in Federal systems. That's wh...

Are you going to do all three signals in one video? Probably. Problem with that? EDIT: Preliminary tests were a complete success! All three siren tones are timed well enough to start the video tomorrow morning. I won't feature the control box much, since it is just one... box... but I did add on a ...

The system in the second video sounded like it could have been one of the systems that is activated in zones, and not the whole entire county at once. The distant siren could have even been in a different county. Did you notice how at least one of the Thunderbolts was sounding in Attack instead of ...

Cant wait for the Thunderbolt! Make it with the blower too. :twisted: I already have the horn/chopper assembly with rotator ready, but I'm planning on redoing the single control box and adding a blower. Hopefully I can get a sound for the blower itself! If anyone has a clip of the blower only, PLEA...

I think this is the one: http://www.youtube.com/watch?v=Fl4PuI5tVz0 This is the EOWS 612 by Sheldon Park in Livonia, MI doing the Alternate Wail (or hi-lo wail). The acoustics... breathtaking! And I never knew the EOWS had alternate wail, either! And let me just add that those are some VERY well-ke...

Always love videos like the first one... dimwits under a giant black cloud while sirens are blaring just saying "dude, lol, that's a siren hahahah oh wow awesome a funnel cloud" because you just KNOW they're going to be screwed. Oh, and second video is awesome... gotta love (relatively saf...

I'm amazed! The windup sounds better than I expected. You got the acoustics just right on that. I'd try to add some sort of echo effect to the steady tone, though, since it seems sort of dry. I've actually heard the steady tone on Thunderbolts sound dryer than that on days when the wind wasn't blow...

Cobb County and Paulding County, so technically it's outskirts of Atlanta (Marietta, etc which has Whelens and Thunderbolts), I just caught that in the video, but then again, that could also be taken in Atlanta. If the Atlanta Thunderbolts are operational, hurray for them. Most exciting video I've ...

Eh... it's hard to tell, but the audio quality seems to whisper "fake". I'm going to hold out until someone posts some credible arguments from either side.

WOAH WOAH WOAH. The Atlanta thunderbolts are OPERATIONAL?!? I thought they deactivated them YEARS ago! Well, at least they don't have a mix of Thunderbolts and ATI's. Poor cat must be scared out of his mind v.v "I got ya hookup dawg, just hang in there!" But hey, wait a second, why couldn'...
