May 11 1921with a crowd of 500 and the Hillsboro mayor in attendance.World’s second-largest tower relayed wireless messages. "Hillsboro Argus", October 19, 1976.] Built on 330 acres the station had one large tower at a height of 626 feet surrounded by eight shorter towers arranged in a circle around the main tower in the center. Workers dug out 14 feet deep concrete bases to secure the towers under the guidance of the engineer J. L. Miller. Constructed of steel, the station cost $300,000 to build.
By 1938 the station was owned by Mackay Radio & Telegraph Company, a subsidiary of International Telephone & Telegraph Corporation. Then during
World War IIthe United States governmenttook over the operations. It was then operated by the United States Coast Guard. In 1951 the station was abandoned and subsequently torn down in 1952.
The tower was operated remotely from
Portland, Oregonand was capable of sending telegraphmessage as far away as Asiaand Europe. The eight smaller towers were 1,500 feet from the central tower. Utilizing short-wave radio signals, the station would transmit point-to-point to regional transmitters such as in San Francisco, Californiaor directly to ships at sea. On site was also a large concrete building 60 feet by 80 feet and 20 feet tall. In addition to this building there was a transmitting station on Council Crest in Portland and the main office was in the Postal Building in downtown Portland. This downtown building is where all messages were received and relayed. The cables supporting the towers were one and one-quarter inch in diameter.
