Jim Creek Naval Radio Station

This newsreel shows the Navy opening the worlds largest radio transmitter back in 1953. Operating at 1 million watts the VLF station operates on 24.8 kHz.  It was known as Jim Creek Naval Radio Station. It is still in operation today and is primarily used to send orders to submarines in the Pacific fleet. David Sarnoff appears in the film to inaugurate the transmitter with it's first message.

MOVIE NIGHT!

This is a Universal International News Reel  about what was then, the worlds most powerful transmitter at 1 million watts. David Sarnoff inaugurated the station with the same teletype he ostensibly used to relay emergency messages about the sinking of the Titanic. It's grandstanding.  You can read the real story here.

In the reel they refer to the VLF (very Low Frequency) radio station as Radio Jim Creek, it's actual calls are NLK and it operates on 24.8 KHz.  It's in Jim Creek, WA near Portland, OR. It's primary function is to relay messages to submerged submarines.
