THE LWT REGION

Transmitter maps of the LWT region and details of how to tune into ITV1 London on both digital terrestrial and satellite services.

VHF 405-line coverage, 1968 to 1985
The Independent Television Authority's London service area from a map published in an 'ITA London' booklet from March 1967, a year and a quarter before London Weekend went on-air. The reach of the main transmitter at Croydon, broadcasting on Channel Nine, ranges almost from Swindon in the west to Clacton in the east, and Northampton in the north to Worthing in the south, covering a quarter of the UK's population. VHF 405-line transmissions ceased on 3 January 1985 and, in reality, most LWT viewers by the mid to late 1970s would be viewing 625-line pictures from the transmitters below.
UHF Colour Coverage, 1969 onwards
The Thames/LWT service area from an Independent Broadcasting Authority map published in 1979. The main Crystal Palace service area is in pale blue, and the main Bluebell Hill transmission area is in grey. The dark blue area represents the secondary service area of both transmitters and the hatching denotes areas served by the larger relay stations. From 1 January 1982, Bluebell Hill was switched to provide signals for TVS and then Meridian Broadcasting, leaving LWT and Thames with the Crystal Palace main station and associated relay transmitters. The Crystal Palace analogue UHF signal is due to be switched off in 2011.
Digital Terrestrial Television (DTT) coverage
London Weekend Television, now branded ITV1 or ITV1 London, broadcasts on the Crystal Palace DTT transmitter, Multiplex 2, Service ID 8261, with a power of 20 ERP (KW). The DTT signal was doubled in power from 2001. To find out if you can receive these signals click here. By 2011, when digital switch-over takes place, more Crystal Palace relay stations will be equipped to transmit DTT, extending the coverage area. Currently, Reigate, Guildford, Tunbridge Wells and Hemel Hempstead relay stations transmit digital signals.
Digital Satellite Television (DSat) coverage
ITV1 London is broadcast on the Sky Digital satellite platform. Viewers in the official coverage area will receive the station on channel 103 of the Electronic Programme Guide (EPG). Viewers from outside this area can view ITV1 london on EPG channel 963 (with audio description function). To manually tune, go to 'add channels' and input the following frequency information: 10758 V; SR 22000; FEC 5/6.
