Check YouTube, they have hours and hours of radio broadcasts from that day. I think Oreon Samuelson (farm market reporter) was the first radio announcer to make the report. He was around forever, I recall his booming baritone reporting March feeder cattle prices and June hogs on 1040 WHO into the 1990s.
Yes, David Von Pein’s YouTube channel is the go to for all things JFK.
Believe me- i have!!
This one was live as it happened across the street from the knoll- it was not at the farm market...
