Yes, Tom, AM was quite different than it is today. WCCO is a clear-channel
station licensed as such by the FCC.WNYC [AM] was its secondary and had to
conclude broadcast at local sunset through the fifties.  WCCO did not have
a directional array. Frequency response was wide in the thirties and
forties, and the ground wave from its Anoka, MN transmitter ensured
coverage throughout MN, NDAK, SDAK and WI. Classical music was a daily
feature after 10:15PM until the late fifties until an "easy listening"
format replaced it.
