The transmitter building comprised two rooms with a window between them: the “High Tension” Room housed the spark-gap transmitter, and the Operating Room housed the receiver, operating controls and switchboard. The transmitter power came from a 75hp Gardner engine in a separate building, the “Engine House”.
In the photo above, blowers can be seen mounted on the wall below and to each side of the shelf holding the keying relays. Whether this was the original design or a later variation is unknown. In the next photo, there is a single blower, apparently sitting on a stool in front of the shelf. Other photos on this page show a blower attached to the front edge of the shelf.
