Wheeling/Northbrook FSK Siren polling with my new scanner

8:30 PM siren polling. Decided to finally film a video of it again but this time with my new scanner! As you can see it works really well. Eventually, I plan on filming one of the local 2001s performing a weekly growl test using this scanner as it can pick up the siren activation frequency for my town’s system as well as every other siren system on NWCD that has sirens with Fulton radios
