last baseball game i was at all those freq's were full of custodians, vendors and other talk that was unknown.
NFL is some EDACS system I have never seen posted (assume its not something that uses normal controls)
also i would suggest like others, buying this book

the following is some data on the trunks that are not normally government stuff.
