Moorside Edge Transmitting Station
Moorside Edge transmitting station, opened in 1931, was originally constructed to radiate the BBC's North Regional (from 17 May on 626 kHz) and National Programmes (from 12 July on 995 kHz). It is – at 400 kW – one of the most powerful mediumwave radio transmitters in Britain. Formed of two 158-metre-high steel lattice towers, it is located just above Moorside Edge (). Other nearby transmitting stations are Holme Moss (11.56 km, bearing 168.17°) and Emley Moor (15.4 km, bearing 99.41°).
