Summary
Typewriter used to transmit Morse character signals to a transceiver and 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 Treager invented this typewriter accessory for his pedal radio (or wireless) set in 1931, specifically for people living on remote outback homestead stations, who had difficulty learning Morse code. When the keys are operated, a metal bar (with impressions) beneath them strikes a metal shaft which sounds the corresponding Morse code for that letter to the transmitter.
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).
