In addition to the main station at 1550 kHz, WUCO is relayed by an FM translator, to widen its broadcast area, especially during nighttime hours when the AM frequency reduces power to only 6 watts.
The station went on the air in November 1960, and, with the exception of a brief period in 1999-2000 using the call sign WYGS, the station had always been known as WMSK.[4]
