Moorside Edge, originally constructed in 1931 to radiate the BBC's "North Regional" (from May 17 on 626khz) and "National" programmes (from July 12 on 995khz).[1], has one of the most powerful mediumwave radio transmitters in Britain at 200 kW erp. Formed of two 158 m steel lattice towers it is located just above Moorside Edge (grid reference SE070154). Holme Moss is on a bearing of (168.17°, 11.56km) and Emley Moor is on a bearing of (99.41°, 15.4km). As with most MW transmitters a good "signal earth" is important and this is assured by the waterlogged nature of the ground on which it is built. The station is now owned and operated by Arqiva. As the site is located on the Pennine Hills, signals can be received from very long distances; Signals can be received as far North as Scotland, as far South as the Midlands, as far West as Dublin and can be received past the coast on the East of the country.
