The station broadcasts across the City and South Cambridgeshire on 105 FM, on its website https://cambridge105.co.uk/ and on DAB Digital Radio seven days a week.
In March 2004 Karl Hartland and Lucy Clifton began an internet radio station that they called 209radio, named after their address 209 Campkin Road in Cambridge.
Within a few months there were 20 such shows each week with the station on air during weeknights and weekends, with contributors eventually ranging from members of the homeless community to the elderly and a group of 14-year-old girls.
[3] Although run almost entirely by volunteers (with three paid staff members), over the next two years, the station struggled to raise the £60,000 required to stay on air and eventually in February 2010, despite a strong following around the city, 209radio ceased broadcasting.
Due to the low budget and limited time allowed alongside volunteers' day jobs, progress with construction was slow.
TuneIn[5] support allows listening via smart devices, such as Amazon's Alexa, Google's Home, and internet connected speaker systems such as SONOS.
The first broadcasts from the site began as early as December whilst building work continued around both live and pre-recorded programming.
Daytime programming covers a popular mix of music from the 1960s all the way through to the present day, whilst specialist picks up on a diverse range of genres.
The station's weekday daytime output consists of music from the 1960s to the present day with a greater emphasis from the 80s onward and a mix of local topical debate and discussion.
Key presenters across the daytime include – Early Breakfast from 6 – 7am (Brian O'Reilly), Mid-Mornings from 9.30am – 12pm (Alex Elbro, Chris Brown, Matthew Parrot) and Afternoons from 12 – 2pm (Stu Wren, Michelle Davey, Scott King).
These include Cambridge 105 Radio's annual Macmillan World's Biggest Coffee Morning[14][15] held at its city centre studios and also broadcast live on the air, raising over £1,500 in total for the cancer charity from 2013 to 2017.
