“Larry Richards on the AGA (Air Ground Air) circuit. 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.”1
The Musick Memorial Radio Station was officially opened by New Zealand Prime Minister Peter Fraser on 12 January, although it had been in operation since 1939.
Musick Memorial Radio Station was opened in 1942.

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.2
After the war, coastal shipping and civil aviation services remained at Musick Point.
