Three sensors will pick up the 12th man energy for Saturday's game. KDK is a permanent PNSN station and is the station that picked up the 2011 Beast Quake. It is located in a building to the west of the stadium and very near the US99 ramp up to Alaska Way Viaduct. and is thus very sensitive to vehicle traffic (lots of wiggles all the time on it). HWK1 is located on the ground floor east of the 20 yard line and close to the rail lines just east of the stadium (increased signals that last 1 to 3 minutes now and then). HWK2 is located on the upper deck in the west stands.
