There is practically no difference in night operation of AM in either
quantity or power of stations between 1978 and today.



How many daytimers were allowed to go to 24 hour operation in the 70s and
80s? One example is WJJD which started wiping out KSL's very listenable
nighttime signal in Chicago during that time period.
