Another time-sharing arrangement still exists between a commercial station and a non-commercial
station in Decorah, Iowa, near the Minnesota border. Commercial station KDEC and Luther College
station KWLC share time at 1240 kHz. FCC records indicate that the stations broadcast from separate
transmitting sites. The KWLC web site gives the station's
hours as 10 pm to 1 am on weekdays and 7:00 am to 1:00 am on weekends.
KDEC's web site doesn't provide a schedule of the station's
operating hours. Presumably it broadcasts when KWLC isn't on the air, but it appears likely that
neither station broadcasts in the overnight hours.
FCC records indicate that KDEC had at one time tried to move to a different frequency, thereby
eliminating the need to share time. An application from 1983 contains this notation:
CP CHG FREQ 1200KHZ, INCR NIGHTPOWR 1KW, CHG TL3.5 MI SW OF DECORAH ON US 52, 43 15 06 91 50 24
CHG FROM NON DA TO DA-2, GO FROM SHARE TIME OPR. TO SEPARATE FULLTIME OPR.
In English, that means the station wanted to move to 1200 kHz, increase nighttime power to 1,000
watts with a directional antenna using separate patterns day and night, and relocate its
transmitting site. However, two requests in 1984 to extend the time allotted to build the proposed
facility were denied by the FCC. In 1991, KDEC requested a power decrease to 580 watts and a change
in transmitting coordinates, indicating that the station was moving its transmitter site. The
proposal was considered a "minor change" not requiring an environmental study, unlike the 1983
proposal. It was approved July 11, 1991.
KWLC still broadcasts with 1,000 watts, indicating that it has not moved in the last couple of
decades, at least.
