When the first two radio stations, LBC and Capital Radio, opened in October 1973, site for medium wave transmitters was not complete. As a result, a temporary 'Tee' antenna was strung up between the two chimneys (transmitting LBC on 417m (719 kHz), Capital Radio on 539 m (557 kHz)), until the permanent site at Saffron Green was ready in 1975. Additionally, there were broadcasts of BBC CARFAX experimental traffic information on 526.5 kHz, 1979–1981 & Spectrum Radio on 558 kHz, 1990-2001
