Blake, Crayon is right. Alot of people (myself included) have worked at supplying the best information we have to the Oklahoma database here on RR.com. It's kinda like one-stop shopping for radio frequencies. I'll grant that there are some places not well represented, and some types of information are not yet in the database, but I'd guess 85-90% of everything is there, especially in the more populated areas.
Give the database a gander, I think you'll be surprised, amazed, and pleased at the amount of information that's there. Then, if you have any questions, come back and ask. If anybody can help, they/we will.
