I would like to thank Ed Maxon for his help filling in the blanks for this WCI page.

In the July 1914 issues of Radio Stations of the United States we see a listing for WCI in Newport, RI³

Also in the same publication we see that the station charges for Radiograms which points to it being a commercial station and not a Navy installation.

In 1919 the station is still there judging by a advertisment for the International Radio Telegraph Company, which was the company that emerged from the National Electric Signaling Company after it went into receivership. ¹

Also in 1919 there is a mention of the station in a account of the routine experience of a radio telegrapher on shipboard in the year 1919 on a trip from New York to Denmark and return. The article was written by Donald McNocol.

In 1922 we see that the station is still there, this time controlled by the Radio Corporation which I believe is RCA.
