Whelen Hornet |Full Alert| (Bernard IA)

For the first Tuesday i decided to do a Dubuque and Jackson county test. I hit up Bernard because this is 1 of two hornets left and one that actually has a testing time. I was hoping it would be 435 hz but i cant complain. It was actually decently loud surprisingly. I also don't know what happened with the wind down, it was some weird static noise.
