This view shows radio station KPO as built by Joe Martineau on the sixth floor of Hale Brothers' Department Store in 1922. A piano and a phonograph were provided as a source of program material. The transmitter is the large black panel in the rear, and a light bulb above it indicated when the station was on the air. To the right of the transmitter is a carbon announce microphone and a Westinghouse RC receiver, which was used to monitor for ships in distress.
