Originally named Piccadilly Radio, from its setup in 1974, the station was renamed in August 1988 when it was decided to re-brand Piccadilly Radio's FM frequency to the new name Key 103. In 1990 the station decided to recognise its heritage and incorporated the Piccadilly name back in, with the re-brand to Piccadilly Key 103 but, during the 1990s, the Piccadilly element of its name was eventually dropped. The original Piccadilly Radio, re-branded to Piccadilly Gold in 1990 and then merged with North of England-based AM frequency stations in 1998 to create a network called Magic AM, has now been known as Key 2 since 2014 on the AM frequency of 1152 kHz as well as DAB.
The station broadcasts on the analogue frequency 103 FM, from a 4KW transmitter on Saddleworth Moor and broadcasts on DAB Digital Radio from City Tower (formerly Sunley Tower), along with Winter Hill (above Bolton, Lancs), Saddleworth and Sutton Common (above Macclesfield, Cheshire) on the CE Manchester multiplex. Key 103's programming can also be heard from their website, but only within the UK.
The DAB signal is broadcast from transmitters located at Winter Hill and City Tower, Manchester on the CE Manchester multiplex. With the addition of Sutton Common, near Macclesfield, the DAB signal has a reliable coverage area that includes Greater Manchester, South Lancashire, most of Cheshire, parts of North East Wales and Merseyside, with much better reception than the FM frequency can provide as 103.0 suffers from co-channel interference from other stations nearby.
In May 2016, two additional digital transmitters were launched at Littleborough and Saddleworth.
The majority of programming – local and networked - is produced and broadcast from Key 103's studios in Castlefield, Manchester.
Key 103 broadcasts local news bulletins hourly from 6 am to 7 pm on weekdays, from 7 am to 1 pm on Saturdays and Sundays. Headlines are broadcast on the half hour during weekday breakfast and drivetime shows, alongside sport and traffic bulletins.
National bulletins from Sky News Radio are carried overnight with bespoke networked bulletins on weekend afternoons, usually from the Leeds newsroom.
