Alf Traeger’s Outback Communications Quiz

Whilst Alice Springs had had a long history as a leader in morse code communications (the Overland Telegraph), it was John Flynn and Alf Traeger that set up the first radio base station at Alice Springs. A couple of outstations soon followed, and in 1926, 2-way radio became a reality in one of the most remote places on earth.

But Alf Traeger quickly saw the major obstacle to a wider network – the awkward, heavy duty, glass, copper oxide Edison batteries – as well as the need for a reliable high-power voltage supply to the local transmitter. A simple, durable alternative was essential for ordinary outstation use.
