In the photo above, those AR-88s had the AM broadcast band fitted (as distinct to the low frequency version used for listening to lower frequency beacons as purchased by Civil Aviation). These receivers were used during the 1970’s for monitoring NZ broadcasting stations for the Broadcasting Tribunal. They were VERY good receivers, and would work well in triple diversity for long range receiving of AM stations (such as North American west coast broadcasting stations after the New Zealand stations were switched off at 10:00 pm/12:00 Midnight). As installed, they must have been used for the reception of Morse Code.

A CR150 was used for the Chathams service. It was modified with a 1600Hz filter to remove the tone generated by the “third method” SSB transmitter at Chatham Islands. I removed the CR150s and installed the MST receivers in either 1969 or 1970. Later these were overtaken by the Harris receivers.

In the photo above, the three Marconi CSR-5s in the “Shipping” rack were probably the 2182, 2196 and 2045 receivers fed through to Wellington Radio on land lines (utilizing the “quiet” receiver site at Makara versus the RF noisy site at Wellington Radio.

In the photo above, the six CSR-5s were the Pacific Islands telegraph service for the reception of Morse Telegraphy, fed down land lines to the Operators in the International Telegraph Office at the CPO (such as Apia on 5WB22 on 14625).

In the photo above, the Marconi HR13 receiver to the right (partially shown) was a triple Diversity FSK receiver which was used as part of the Compac Cable restoration scheme, and provided a 192 baud TOR signal through to the International Telegraph Office for four telegraph circuits to London. Two of the four circuits were used by the NZPO, and I assume the others were used by other places like Sydney.

The far ends of the vee aerials were actually connected to coax running down the supporting pole and the resistor terminated at ground level. This was to avoid skewing of the beam due to radiation of the grounding wire.
