The Tangley Company was located at 217 Main in Muscatine, Iowa. Norman Baker owner. 

Norman G. Baker (November 27, 1882 – September 10, 1958) was an early American radio broadcaster, entrepreneur and inventor. He operated radio stations KTNT in Muscatine, Iowa and the border blaster XENT in Nuevo Laredo, Tamaulipas.

In 1924, convinced of the potential of the burgeoning field of radio broadcasting, Baker asked the town of Muscatine to permit a station that would make the town famous across the Midwest. In operation by November 1925, the station received the call sign KTNT, chosen for its explosive connotations but explained as "Know The Naked Truth." It broadcast with 500 watts on 256.3 meters or 1170 kc/s.
