Transceiver used as part of a pedal-powered radio (or wireless) set, developed by Alfred Hermann Traeger (1895-1980) for the Australian Inland Mission aerial ambulance service (later named Royal Flying Doctor Service).

Alf Traeger developed his pedal radio set for people living in remote outback communities far away from telegraph stations. It was designed to be portable, lightweight, robust and cheap. It had a transmission range of 800 miles (1288 km) and was first introduced in Queensland in 1929.

This set is believed to have been used at Mulka Station in the north of South Australia, on the main Birdsville-Maree route to Adelaide. It was named the 'Mary Margaret Kemp Set' in 1931 after the founding President (from 1925-1930) of the Western Division of the Queensland Country Women's Association (CWA).
