Victoria University Antarctic Research Expedition Science and Logistics Reports 1982-83: VUWAE 27

Communications:

Communications:

The VUW seismic party had 3 Compak radios with spare aerials and 5 spare batteries. Communication along the seismic lines on 4703 kHz was excellent page 41 until the seismographs were switched on. Interference from their power supplies was so great that 3m high aerial poles and high transmitter power were needed, and even then the shot instant signals were sometimes not good enough to start the Nimbus reliably. The frequent use flattened batteries in three days, and in the absence of helo resupplies batteries had to be recharged (slowly) from the 24V battery on the D4. A solar panel and voltage converter/regulator would be infinitely preferable!

Communications with Scott Base were generally good although long scheds were sometimes a nuisance if we had messages to pass and were also awaiting seismic shots.

VHF Radios.

We were again unfortunate not to be allocated VHF radios for our scientific work especially when surveying on the Mackay Glacier tongue. Mirrors can be used for very simple messages but they just do not work on cloudy days.
