James its been done before in 1928 !!!

In 1928, thanks to Alfred Treagar, a reliable and accessible form of communication was introduced
-the pedal radio. The pedal radio was accompanied by a typewriter which translated letters into
Morse code.

Once a doctor was contacted by radio, an emergency flight was organised. Flights were made in a
small, open de Havilland DH 50 flown by Arthur Affleck, who was a pilot with the small bush
airline, Queensland and Northern Territory Aerial Services Ltd (QANTAS)
