They are in the database, from the main page search EAA. It takes you to Winnebago county businesses. The list looks accurate, most are freqs I used last year. I'm still trying to figure out how to download. I am a premium subscriber.

I ran across this site which has a nice list of Freqs used at the Air show.
Good Luck & have fun if your going there. Add to the list 133.850 Air show Boss.
