(435hz) Whelen Vortex R4 | Full Alert & Ambiance | Yukon, Oklahoma | 11/16/24

At 12:02:05 the City of Yukon conducted a weekly test of their Outdoor Warning Sirens on Saturday, November 16th, 2024, the test consisted of a 3 minute Alert. After discovering this was 435hz a few months back I knew I wanted to record it since OKC no longer has 435hz in their system. Which means this is the last 435hz Whelen in the metro. The wind was ridiculous, as you can tell, so excuse that. Yukon was 2 minutes late so we could hear a Vortex in OKC at first. I didn’t include the full ambiance of it though since it was quiet, although you can hear it pretty well in the very beginning of the video INFORMATION Date Recorded: 11/16/24 Main Shot: Canon PowerShot SX540HS Second Shot: iPhone 14 Pro Audio: Canon PowerShot SX540HS Weather Conditions: Mostly Sunny System: City of Yukon Tests: Every Saturday @ 12:00PM Weather Permitting: Yes Tests Cancel For: Rain, chance of severe weather Test Cycle: 3 minute Alert Time of Activation Today: 12:02:05 Siren Model: Whelen Vortex R4 Controls: ESC-2020 Hertz: 435 Replaced: N/A Siren Location: Northeast corner of Welch Park Distance from Siren: About 215ft Sirens Heard: Yukon: Whelen Vortex R4 (435hz) - 216ft Whelen WPS-2810 (560hz) - 0.94 Miles Federal Signal 2001-130 DC - 1.16 Miles Whelen WPS-2810 (560hz) - 1.71 Miles Oklahoma City: Whelen Vortex R4 (560hz) - 1.66 Miles Other Enthusiasts Present: Oklahoma Tornado Sirens And Storms -    / @gabrielcl2t22a   Check out my other videos: Recordings:    • All of My Siren Recordings   Ambiances:    • All of My Siren Ambiances   I post siren pictures on Instagram:   / andrewwt5020   If you would like to use my videos, you do not have to ask, just give credit.
