On the right of the radio operater (possibly Max Crockett)is the Lorenz Radio Range monitor unit. The Lorenz beam was short-wave landing radio beacon that had the advantage of not being subject to atmospheric interference.
A permanent roster of Aeradio operators at Nhill worked around the clock to provide full-time communications and navigation support to aircraft flying between Melbourne and Adelaide. The radio operators and associated radio technicians and their families were a valued part of the local community.
