Got my mom to take me to Owensboro KY today to record one of the many Whelen Vortex's that the county has. This siren is an older Whelen Vortex R4 located at 1316 Scherm Rd, Owensboro KY. It sounds a one minute wail cycle and continues for a few rounds of rotating after the siren stops sounding. The siren is sounding for the weekly test conducted every Friday at noon My best friend Brooke was also there with me as I was recording.
