DeKalb County Airport is too small to have the usual tower and ground control freqs. Unicom freq 122.7 is used by the pilots and control is under the authority of Chicago Center for aircraft arriving or departing the airport.
Thanks to Gary, I found out everything I need to know. I wasn't even aware that my local airport didn't even have a control tower. First time I actually am getting into the air stuff. Thanks for all the help though
