local Wenvoe transmitter which carries the Wales variations of BBC One, BBC Two, and ITV. This was originally because the Wenvoe transmitter broadcast S4C (with programmes in Welsh and some prime-time English programmes from Channel 4 scheduled at much later times) rather than Channel 4 itself. Even after digital switchover when transmitters in Wales also began to broadcast Channel 4 in addition to S4C, some households continued with their preference for the West variations of BBC One, BBC Two, and ITV, and having Channel 4 (not S4C) as number 4 on the electronic programme guide. Power on analogue transmissions was 500 kW (ERP) for BBC 1, BBC2, HTV West, Channel 4, and 126 kW (ERP) for Channel 5. The latter was transmitted outside of the original C/D grouping of the transmitter but most homes in reasonable signal areas for the C/D group could receive it with their C/D group aerial. All six digital multiplexes were transmitted at 10 kW until switchover in 2010 when the power on the "BBC A", "BBC B/HD" and "D3&4" multiplexes was boosted to 100 kW. In 2011, SDN was boosted to 50 kW and in 2012 the remaining two Arqiva multiplexes were boosted to 50 kW too. In June 2019, as part of the 700MHz clearance programme, Mendip became K group (excluding muxes 7 and 8, which are due to be switched off between 2020 and 2022). This means that homes in poor signal areas which still have a C/D group aerial may have difficulty in receiving all multiplexes. Mendip's population coverage is around 1.5 million, although some homes in the immediate vicinity, such as those in Cheddar, are unable to receive a signal due to being in the shadow of the Mendip Hills and therefore depend on local relays. South East Wales Television Many households in SE Wales use the Mendip transmitting station for their television post digital switchover. Due to the proximity of these areas to Wenvoe, the signal from Wenvoe is too strong for most TV sets, requiring an attenuator to be fitted to maintain a reliable signal. To eliminate hassle, many households instead choose to opt for Mendip, which is the ideal distance to provide a reliable & high quality signal. Made in Bristol, a directional beam to the Bristol area from Mendip, is also receivable in SE Wales. Radio The Mendip Transmitting Station also broadcasts the digital radio multiplex for
