A Complete Broadcast day Sept. 21, 1939

This was an interesting find. In 1939 the radio station WJSV recorded an entire broadcast day.
WJSV originally went on air in 1926 as WTRC based in Brooklyn, NY. It was named for the Ttwentieth district Republican Club. Interestingly enough that batch of Republicans were also members of the KKK. The federal government ran them out of New York City.

A year later it moved to Arlington, Virginia, as 1470 WTFF-AM. It was named for The Fellowship Forum, the Klu Klux Klans newspaper. Soon after flipping calls to WJSV; now named for the papers publisher James S. Vance.In 1932 CBS bought the station ousting the bigots in bedsheets and cleaned house. They changed the city of license to Washington D.C. and changed its call letters to WTOP-AM in 1943. But while it was still WJSV in 1939 on September 21st an entire 19 hour broadcast day was recorded. Starting at 6 a.m. and running through 1 a.m. a veritable time capsule was created.
The project was at the behest of the the National Archives. But this was no random selection. PD Harry C. Butcher was a naval aide under Eisenhower, and it was he that first named FDRs fireside chats and his start reporter Robert Trout that introduced the president each week.
