Dartmouth Broadcasting began in 1924 when members of the amateur radio club obtained a federal license to broadcast on the AM band, at 1170 kHz, as WFBK. Later renamed WDCH, the station continued until the fall of 1925 when an inadvertent obscenity uttered over the air caused the college president, Ernest Martin Hopkins, to permanently shut it down. Radio finally returned to Dartmouth in 1941 due to the efforts of a group of determined students (led by Richard Krolik, class of 1941) and younger faculty who persuaded Hopkins to give the students a second chance.
