We have been searching the northern sky for ultra-narrowband carriers of intelligent extraterrestrial origin at 21cm wavelength. The dual-polarization 65,536-channel receiver has a resolution bandwidth of 0.03Hz, matched to the Drake-Helou spreading of the interstellar medium. This maximizes signal/noise ratio, and simultaneously rejects carriers of terrestrial origin. The results of 15 months of observation are summarized.
