Equipment racks at Auckland Radio

We do not have dates for the following series of photos, although the Marconi Canada CSR5 receiver, which appears near the bottom of the first photo, was introduced in 1942.

Although it is believed that these photos were taken at Auckland Radio, it is not yet clear whether the racks were at the receiving station (Musick Point) or the transmitting station (Oliver Road). The racks do not appear in any other photos we have of either site.

The racks all appear to have been mounted on top of desks.

Equipment Rack 1 at Auckland Radio

‘Bay 1, Misc. Eqpt.’
The 3rd panel from top is labelled ‘Radio Receiver.’ The 5th panel (with handset) is labelled ‘Order Wire Unit’. Below it is a ‘Remote Control Unit’. Then the Marconi CSR5 receiver, and finally a ‘Receiver Switching Unit.’

Equipment Rack 3 at Auckland Radio

‘Bay 3, No.2 H.F. G/A’
(G/A presumably means ‘Ground to Air’ and refers to civil aviation communications.)
The 3rd panel from top is labelled ‘Power Supply.’ The 4th panel provides storage for 2 coil sets for the National HRO receiver. Below that is a ‘Remote Control’ for a transmitter. Then another ‘Remote Control Unit’ above the National HRO receiver (made under licence by Collier & Beale in Wellington). At the bottom is a ‘Receiver Switching Unit.’

Equipment Rack 4 at Auckland Radio

‘Bay 4, M.F. G/A, Emer. Xtr. Control’
(G/A presumably means ‘Ground to Air’ and refers to civil aviation communications.)
The 3rd panel from top is labelled ‘Power Supply’ and the 4th panel is unreadable in the photo. The 5th panel is the emergency transmitter control with inputs for a microphone and telegraph key. Below it is an ‘(Unclear) Control Unit’ and a Type 641 MWB-2 MF receiver made by Radio 1936 Ltd in Auckland. At the bottom is a ‘Receiver Switching Unit.’
