Seattle PD was using TG 24912 and Fire/EMS was on TG 2320 at the game. The SPD unit handling traffic outside the stadium after the game was not on TG 24912 as I could hear radio traffic on his portable that was not from that talkgroup.

After the game, I heard a constant carrier on 470.3125 that may or may not have been related to the stadium. I also got a CloseCall hit outside the stadium on 902.9875 that again I don't know if it was related.
