For most of its history, UKC Radio was available on 300m Medium Wave (officially 998 kHz AM, though it apparently used a 1 MHz crystal as these were far cheaper) via induction loops which were on the top of the college buildings - meaning you could only hear the station in limited parts of the campus. The inductive loops used a figure-of-eight configuration to prevent off-campus radiation in accordance with the licence conditions. These loops actually operated as a kind of leaky feeder, with a single strand of cable draped around the roof of the buildings, connected to a coax cable that linked via the central boiler room to the original transmitter (called Amanda by the engineers) in Eliot. This was replaced with a Wireless Workshop transmitter in 1995 (called Fred).
