Text by This phone was mounted on the FPS-18 Control Monitor, at the north end of the equipment room centered between the two rows of radar transmitter and receiver cabinets. It was most likely connected to an identical phone in the radome to allow technicians to coordinate calibrating the transducers that sent the antenna position and speed to the Control Monitor and FST-1 Coordinate Data Transmitter. Operating the crank would turn the magneto and cause the howler on the receiving phone to, well, howl, alerting the person on the other end to take the call. Being sound powered, the phone did not require batteries or any other source of power to work.
