Pulse forms part of the LSESU Media Group alongside The Beaver newspaper, Clare Market Review and LooSE TV.

It is staffed by student volunteers who act as Disc jockeys, technicians, and producers, and is funded by the LSESU, advertising revenue, and donations.

The station broadcasts in three slots from October to December January to March and April to June each year, with vacations in between the School's Michaelmas, Lent and Summer Terms.

Membership consists of over 50 DJs playing a mix of mainstream and specialist music, as well as several dozen other students in the areas of promotions and advertising, broadcast journalism, technical, production and programming.

In the past Pulse has conducted interviews with José Manuel Durão Barroso (President of the European Commission), Jacqui Smith (UK Home Secretary), John Edwards (2004 Democratic US Vice-Presidential Candidate), Clare Short (UK MP), Valéry Giscard d'Estaing (former French President), Kim Campbell (former Canada PM), Jon Snow (Channel 4 Newsreader), Alan Fletcher (Dr Karl Kennedy in the soap Neighbours) and Levi Roots amongst others.
