WILL AM's signal reaches pretty much all of Indiana and Illinois during daylight hours. For some goofball historical reasons, their license requires them to go to low power after dark, and it gets hard for me to pick them up 40 miles from the tower. (WILL's tower is located a ways west of Champaign.)
Morris (my-husband-the-ham-radio-person) says that the reason the station has to reduce power at night is, that propagation of radio signal is much better at night, (I can recall occasionally hearing WGN out of Chicago late at night down on the Texas gulf coast, for instance) and "who in Africa wants to hear Illinois agricultural weather reportage?"
