The 6th Cambridge Survey of radio sources covers most of the sky north of Dec>30{deg} with an angular resolution of 4.2x4.2cosec{delta} arcmin^2^ and a limiting flux density of 120mJy at 151MHz. This paper, the first of a series, describes the telescope and the methods used to produce the survey maps and source list, and presents maps of a circular area of radius 10{deg} centered on the North Celestial Pole and a list of 1761 sources north of {delta}>+80{deg}.
