Auckland Radio 1920-1929

1923: The wireless station was relocated to a room on the first floor of the CPO, adjoining the Telegraph Office.

GH Robins became manager during the 1920s (date unknown).

1927: Auckland Radio VLD changed to ZLD as part of a new international agreement on callsign allocation.

By the time Awanui closed in 1930, due to the cost of maintaining its isolated facilities and as a result of the shift from long wavelength spark transmission to short wave “cw” signals, Auckland Radio was back in operation.

When aviation services started in the 1930s all communication and radio navigation aids were run by the Post Office.
