They did indeed. Power WAS controlled by the FCC back then, however. Indeed,
Crosley only ever had experimental authorization to run at 500kW and had to
renew this every six months. In 1938 the Senate passed the Wheeler
Resolution which "requested" the FCC set an absolute limit of 50kW and WLW
had to go back to 50kW. The 500kW broadcasts were carried out under the
experimental callsign of W8XO and could be heard in London!
