On September 15, 1935, WMAQ once again changed transmitter sites. It relocated to Bloomingdale, with its power increasing from 5,000 watts to the maximum 50,000 watts. Clear channels were reassigned in 1934, with Illinois losing a frequency and Pennsylvania gaining it. Preserving its clear channel frequency for KYW meant Westinghouse needed to move it out of Chicago. So Westinghouse moved KYW east to Philadelphia in late 1934, leaving an unneeded transmitter building and site behind, which is where WMAQ relocated its transmitter. WMAQ's new daytime signal provided secondary coverage to most of Illinois, including Peoria and Springfield. It also provided a strong signal to much of southern Wisconsin (with Milwaukee getting a city-grade signal) and almost half of Indiana. At night, it reached most of the eastern three-fourths of North America.
