Around the World with Louise Brooks : Paramount's KNX Radio Station in Los Angeles

Who might know more about the Paramount radio station, KNX in Los Angeles? Is it the same, or related to, the KNX super-station currently heard in the LA area? Is there a history of the station or of broadcasting in the LA area that might be consulted? Are there records as to what was broadcast in the late 1920s? (I have looked at old newspaper listings, and they don't reveal all that much.)

I am wondering if Louise Brooks was ever heard on the station, or were one of her films featured? The microphone below pictures Clara Bow and two of Brooks' two-time co-stars, Adolphe Menjou and Wallace Berry.

The other day, I came across a few clippings about the station, which according to the second clipping went on the air on Armistice Day in 1928. These clipping seem to be somewhat at odds with the Wikipedia history of the station in that the station went on the air before 1928 and they don't mention the Paramount connection. Might Paramount have leased air time, or only broadcast at certain times? I would like to learn more. Any suggestions would be greatly appreciated.

Here is a clipping which notes the stations 1927 debut, and what was heard on that day.

And here is an article from the San Bernadino County Sun newspaper about the station's launch. There is only little mention of Paramount.
