The broadcasting station that became UKC Radio had its origins in the autumn term of 1967 as an audio feed through the radiator system. This was inspired by an article in the magazine Practical Wireless entitled ‘Communications through the Ground’. The article explained how an audio signal injected into two separate earthing points could be detected by connecting an amplifier to two more earthing points nearby. Budding electronics students decided to test this out in Eliot College by connecting the loudspeaker output of a HiFi amplifier between the mains earth and the central heating radiator system. The signal could be heard loud and clear in study bedrooms throughout the college by connecting a modified transistor radio, used as an audio amplifier, between the radiator and the metal table lamp, which provided a connection to the mains earth.
