Hello everyone, this is my first post here. I am interested in broadcasting history, especially AM radio and Chicago history. I have a technical question and a trivia question.
On one occasion (that I know of) the FCC allowed daytime and limited time AM stations to stay on all night. Did the FCC or anyone make any observations of the skywave interference that this created? I suspect that the AM band was a mess. How many stations stayed on?
Trivia question: What was the occasion that brought this about? Hint: It helps if you are over 65!
