Art, science, technology and tomfoolery

The ACMA’s proposed Class licensing for amateur radio will be a quantum step in the evolution of amateur licensing in Australia, such as we have not seen previously.

Accordingly, this called for a radical design concept for our cover, this issue. This has been addressed in two ways. Firstly, the central illustration of the issue at hand, with an exceptional cartoon by Carmel Morris VK2CAR. And secondly, an outstanding graphical design to frame the cartoon and stop readers turning the page – just for a moment, to contemplate what’s happening in the world of amateur radio in Australia.

The concept and style of Carmel’s cartoon is based on another visual meme that satirises the technical education system, originally published in a local electronics magazine. That was by Brendan Akhurst, once a policeman, who gained notoriety for the cartoons he produced for local technical publications that I edited in bygone decades, CB Australia and Electronics Today International (ETI). A detail from that cartoon is reproduced here.

Carmel has reprised Akhurst’s concept of manufacturing machinery re-shaping students – in this case, rotund hams with apparatus licences are satirically refashioned into “cubic buddies” with Class licences. In addition, she has extended the illustrative metaphors with visual references to Picasso’s Guernica. Observant readers will find the references to Van Gogh and Terrence Nation.

The graphical design concept framing Carmel’s cartoon is adapted from the work of Dutch artist, Pietr Mondriaan, by our own highly skilled graphics artist, Sergio Fontana VK3SO. Mondriaan was co-founder of the De Stijl (‘The Style’) movement. From a century ago, he created a series of works that reduced scenes to the essentials of form and colour, simplifying compositions to vertical and horizontal, using only black, white and primary colours, and avoiding symmetry. Sergio’s cover design is based on Mondriaan paintings such as the one shown here: Composition with Large Red Plane, Yellow, Black, Grey and Blue (public domain; Wikipedia).
