5IT was a BBC radio station which broadcast from Birmingham, England, between 1922 and 1927. It was the BBC's second station, going live at 17.20 on 15 November 1922, the day after 2LO started daily BBC broadcasting from London and one hour forty minutes before 2ZY launched BBC broadcasting in Manchester. It was replaced from 21 August 1927 by the higher-powered 5GB broadcasting a Midlands regional programme from Daventry.
