Radio triggers

[Sandman_28054]

I have found a web-site that will allow you to d/l radio broadcasts from the "golden age of radio."

Some of these date through the war years.

Question:

I'm listening to a radio broadcast of Abbott & Costello that was braodcast in 1943.

Entitled "At the Circus with Alan Hale."

How can one add these braodcasts to the radio and make them available during the year it was actually broadcast?

All these are period broadcasts:

And here is another list of files that covers WWII in audio from 1941: after Pearl Harbor; to 1944: before D-Day:

Some of these include President Franklin D. Roosevelt's "fire-side chats."

Would it possible to d/l these and make it so that on the date they happened, they broadcast over the radio?

And if so, would you tell me how to do it?

Thanks.
