Awesome set of antique radio tuning dials, found at Indiana Radios.
Considering they all did pretty much the same thing, there seems to be a ton of variety in these things. I guess from country to country, or with different radio companies, you had a completely different dial.
From a graphic / typographic standpoint, they just blew me away. Such unconventional type, line, and color choices, but also really ubiquitous at the same time… like you’ve seen them all before somewhere, but also never really seen anything like it.
I also found it interesting because they represent an era of technological transition. As radio took off and people started to navigate the airwaves, the graphic identity of the radio seemed to neglect the state-of-the-art electrical nature of the instrument, and was more akin to the nautical navigation devices of the past. People understood the compass as the main way-finding interface, so I guess it was only natural to relate the radial knobs and dials to that graphic system.
An intriguing idea… that all those ham radio guys were actually mapping sonic space, dialing each other up, triangulating positions through concentric circles, writing down important headings or frequencies. Sounds more and more like the surveys of 15th century cartographers. Even the name Zenith (as in the amateur radio company from Chicago) is a direct reference to a projected line from the earth to the heavens, and has it’s origin in the field of Practical Geodesy - the science of earth measurement in three-dimensional space.
Today it’s just as commonplace for us to have a digital radio dial, since we navigate the world through the same kind of digital space, with electronic coordinates on our GPS.
But yeah, aren’t they cool? And as long as we are making connections about the graphic implications of such symbols, I’ll say that I’m not surprised at all to realize that the circular dials are also very reminiscent of other directional systems: the medicine wheel of the American Indian, or even the Mayan calendar. Alright, maybe that’s a bit of a stretch, but you have to admit, the colors and lines on some of these things seem to fit the description.
I think contemporary designers can learn a lot from the intuitive usability of analog displays like this. Then again, there’s so much beauty in the computer as well, so…
