A number of transmitters were installed on the site over the years, the most powerful being an AEG-Telefunken S4006 which had a maximum output of 600 kW.
Other transmitters included two Doherty 250 kW units, designated ORF 2A and 2B (both originally at Crowborough), whose outputs could be combined to give 500 kW on a single frequency [REF].
