This opportunity was exploited to carry out a pilot survey at 20GHz over the area for δ>+72.3°. This paper describes all the phases of the observations, as they were performed using new hardware and software facilities. The map-making and source extraction procedures are illustrated. A customized data reduction tool was used during the follow-up phase, which produced a list of 73 confirmed sources down to a flux density of 115mJy. The resulting catalogue, presented here, is complete above 200mJy. Source counts are in agreement with those provided by the Australia Telescope 20GHz (AT20G) survey. This pilot activity paves the way for a larger project, the K-band Northern Wide Survey (KNoWS), whose final aim is to survey the whole Northern hemisphere down to a flux limit of 50mJy (5σ). Description: In 2010 winter, we produced a total intensity test map covering the Northern polar cap (∼880deg2, δ>72.3°), which allowed us to deeply check the new hardware and software facilities - the MF, the analogue continuum backend and the telescope control system - which is a new system based on the ALMA Common Software. The actually chosen band is 20-22GHz. File Summary:
