GarlyDog, there are several ways to get started, (1) Google search "Amateur radio in Illinois",(2) Google search "HamFests in Illinois" and attend one,(3) check with the local Emergency Management agency or Red Cross chapter and inquire about hams or Ham Clubs in your area and make contact with one,(4) check QRZ.com or radioreference.com and find the local SkyWarn frequency and monitor it in the evenings for a week or so, listen for the Net and the location of upcoming Spotter classes and attend one, (5) the SkyWarn Net is usually a local repeater used by the area hams, listen in on that frequency for the "rag chew" net and classes for Technician Level are announced.
If classes are offered, that is probably the best way to get necessary information and training to pass the test. Several websites have practice tests online for free. If you have even rudimentary electronics knowledge you can start taking practice tests now. The licenseing test isn't difficult, you just have to understand a few basic principles and the rest you can pick up listening. Good Luck and 73s.
