CKDU-FM (88.1 MHz) is a non-profit radio station broadcasting from the campus of Dalhousie University in Halifax, Nova Scotia.

It airs a campus radio format serving the Halifax Regional Municipality area and is operated by the not-for-profit CKDU-FM Society.

After a successful student referendum to fund the station, and approval from the CRTC on October 10, 1984, [1] CKDU started broadcasting on 97.5 FM with only 33 watts.

The station's programming was initially heavily weighted to what was then considered "alternative" popular music, including such artists as Bauhaus, Ministry, Kate Bush and the Cure.

CKDU is one of the few radio stations based in the Maritimes where one can hear local hip-hop, live electronic music, liberal and anarchist news shows, and the like.

Most notably, the show openly discussed the AIDS epidemic occurring around the world and specifically referenced how it affected people in Halifax.

CKDU runs ad spots from a variety of advertisers, usually local nightspots and other businesses aimed at young adult clients.

CKDU is located on the fourth floor of the Dalhousie Student Union Building (6136 University Ave.) and is accessible to the general public.

The equipment consists of a pair of Technics SL-1200s, a mixer and mixing board, a number of CD decks, an audio-enabled computer, inputs for external devices, and a reel-to-reel machine.
