I spent half the day at McChord on Saturday thanks to a family emergency, and most off today.
What did I see? Planes, people and lines.
What did I hear? Show control was the McChord Tower 124.800. I'm sure various acts had various discrete freqs; I'm not well enough versed in mil-air to know. Most of McChord's base ops were on the 380-mhz trunked system, 99.4% of which was running full time encryption. Some of the police ops were in the clear, a rough guesstimate would be 30%. Pierce Transit was running special bus service to the show; I ended up riding that both days, and after leaving, rounding out the listening from the top of the Lakewood Sounder Station parking garage.
I grabbed shots of 3 freq cards; most were covered or wiped off (dry erase boards). I saw a kneeboard with a full page of freqs, some kids in the MH-47 cockpit was playing with it before a crew chief took it away from him :(
From one of the Army helos (note button 19, and the VHF freq...WTF?):

From the USCG helo, Port Angeles station:
