The amateur radio transceiver equipment was used by the donor from the early 1970s to the late 1980s. The radio equipment illustrates the donor's fascination with amateur radio and his journey through the radio wave spectrum - from shortwave radio, to joining the Wireless Institute of Australia (WIA) and applying for and being allocated a listener id, to sitting for a Limited Amateur Radio operators licence and the lure of high frequency bands and radio teletype.
Each progression in the system of communication employed brought increasingly complex technological challenges. The archive demonstrates the donor's achievements in building on his levels of skill and expertise in circuit and control system design to deal with these changes.
The donor's eventual employment of a teletype machine in his amateur radio transceiver operations represented a major shift. Teletype machines had been employed as computer input and output mechanisms and by the postal / telecommunication sectors for communications. However the application of teletype equipment to amateur radio was an extraordinary development, in particular it anticipates what even the implementers of modern mobile phone text ability did not anticipate - interpersonal texting.
