Auckland Radio 1920-1929

During the first six years of the 1920s, high levels of electrical noise continued to plague reception at Auckland Radio. Fortunately, Awanui Radio near Kaitaia was able to receive signals and transmit messages via landline telegraph to Auckland.

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

1923:

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

1926:

On the evening of 10 June, Auckland Radio received a message from the steamer Manaia, after the ship ran aground on Slipper Island off the Coromandel Peninsula. The steamer Ngapuhi was diverted to go to the aid of Manaia. All aboard were rescued.

1927:

Due to continuing problems with high levels of electrical noise in downtown Auckland, a remote receiving station was established in Avondale, and this improved reception significantly.

1929:

On 1 January, the callsign of Auckland Radio changed from VLD to ZLD, under the new worldwide callsign allocations agreed at the 1927 International Radiotelegraph Convention. (This was the second change in callsigns, as prior to 1913 there were Auckland – NZK, Awanui – NZA, Wellington – NZW and Bluff – unallocated.)
