In the background is visible the Marconi DF and the remote control for the AWA Transmitter (#100 on 500/390 kHz) used in conjunction with the direction finder for RT contacts with shipping and aircraft as required.1

Notes to photo above:
The primary watch (8523kHz) was kept on the bottom receiver. The top receiver, connected to the loudspeaker, was on 10,900kHz for Awarua Radio ZLB. In the rack above the receivers are two carpenter relays and a Morse sounder on the line circuit to ZLVY Waiuku HF Direction Finder on the edge of the Aka Aka swamp. This DF was part of the network supplying bearings to aircraft.”2

On 19 May, two representatives of the RNZAF reportedly damaged the medium wave direction finding system at Musick Point, while taking photos for the Air Force.
During World War 2, the station conducted numerous services under Post Office control. These included coastal services for shipping, naval intelligence (DF watches), civil and military aviation.
Auckland Radio established a high-speed radiotelegraph link with the RCA station in San Francisco, as a backup in case cables were attacked.3
After the war, coastal shipping and civil aviation services remained at Musick Point.
