I wouldn't say overcrowded, it more conditions. 30 years ago, night-

There is practically no difference in night operation of AM in either
quantity or power of stations between 1978 and today.
30 years ago you could hear WLS in Los Angeles.
You still can when the UT station is off.
How often is the Utah 890 station off? And when did they start broadcasting
at night?
The changes that have taken place are all about the overall noise levels,
not with the stations themselves.
It's my recollection that a number of stations started night time
broadcasting on the "clear channel" frequencies around 1980 or so. But,
hey, I could be wrong. Nevertheless, in 1968 or 1958 or whatever, the clear
channels really were clear channels.
