KRHO was a powerful shortwave radio station broadcasting in English and Japanese languages to the Far Eastern Pacific region in the closing stages of WWII.

We continue our tour of the facilities by introducing Joseph Whitehouse, Engineering Director of the Central Pacific Operations. He supervised installation of the transmitter at Lualualei on Oahu. Operating at full capacity, Station KRHO, one of the most powerful shortwave stations in the world, was on the air 20 hours a day.
