The article reports on a full-time all-sky search for narrowband RF emissions (of presumably intelligent origin) near 21 cm, on a band 380 kHz wide and centered on that hydrogen band (corrected to the Galactic Standard of Rest). The search, underway since 1973 at Ohio State University Radio Observatory, is currently underfunded and understaffed. The importance of beam switching for minimizing terrestrial interference and independence of perceived galactic H emission from extraterrestrial interference are emphasized. The discovery of some cold H clouds is reported. No confirmed narrowband extraterrestrial signals have been found to date between +48 deg and +14 deg in declination above the detection limit (1.5 x 10 to minus 21st power W per sq. m).
