Construction

edit

First structure

edit

The first mast was built in 1966. On 16 November 1966, it collapsed. Parts of the wreckage are still in use as pig shelters. It had been built by the British Insulated Cables Construction Company. It was to have begun broadcasts in the summer of 1967.

Second structure

edit

The structure was rebuilt in 1968 by the BBC. This delayed its first transmissions until 31 August 1968 of BBC2 only. It broadcast ITV from February 1970 and BBC1 from August 1970. On 9 April 1970, the whole region lost the signal when an excavator damaged the station's main cable. The mast was one of three similar types built at the same time by the BBC, with Mendip and Bilsdale.

It is a shorter version of the second Emley Moor transmitter which collapsed whilst broadcasting on 19 March 1969, due to the weight of ice on the structural cables. The Waltham mast has four sets of stay levels as opposed to the six of the former Emley mast. The latter was identical to the current 385m high Belmont mast, both built by the ITA.

It is east of the A607 between Grantham and Melton Mowbray.

Coverage

edit

The mast was originally built to provide BBC2 (on the new UHF 625 lines system) to the East Midlands. It became the main mast for ITV's Central East Midlands from 1982 and BBC East Midlands from 1991. Previously it had carried broadcasts from Birmingham. NICAM was transmitted from 31 March 1992.

It is now the main TV transmitter for all digital terrestrial channels covering the East Midlands, predominantly including most of Leicestershire, Rutland, Nottinghamshire, Derbyshire and parts of Lincolnshire. Waltham is the main transmitter that covers the cities of Nottingham, Leicester and Derby. It can also be received in parts of Norfolk, Staffordshire, Cambridgeshire and Northamptonshire. It is owned and operated by Arqiva.

Digital TV

edit

Waltham first broadcast digital TV on 15 November 1998. In July 2007 it was confirmed by Ofcom that at DSO (Digital Switchover) Waltham would be transmitting five – of the six – MUXes within its original C/D group. For reception of all 6 MUXES a wideband is required. When Waltham undertakes its 700 MHz clearance, between February and March 2020, it will become an A group – excluding MUXES 7 and 8 which are due to be switched off before the end of 2022 anyway (see graph).

Relay stations

edit

The two most powerful relays are at Nottingham situated west of the M1 J26 (covering the whole city and surrounding areas) and at Stanton Moor near Bakewell (covering the Peak District) The Nottingham relay at Kimberley began on 30 March 1973, following tests from late February 1973.[1][2] Channel 4 arrived on 10 February 1984, 15 months after Waltham.[3]

Waltham has also 13 low-power relay stations located in Derby, Leicester, Ashbourne, Matlock, Belper, Birchover, Darley Dale, Ambergate, Ashford in the Water, Parwich, Eastwood, Little Eaton and Stamford.[4]

The area immediately to the north west of the latter transmitter is the meeting point between the Winter Hill, Emley Moor, Sutton Coldfield, and Waltham broadcasting regions and this is why just north-west of Bakewell, the filler transmitters are BBC North West. Stanton Moor transmitter feeds the Darley Dale site, which was Britain's 1000th television relay station.
