Green Bay Press-Gazette built
WJPG – a
daytimer – in 1947 and it began broadcasting with 1000 watts of power on 810
kHz on December 12, 1947. Nighttime service was added in the station's early ears, and WJPG changed AM frequencies from 810 to 1440 kHz on May 24, 1951. Daytime power was increased to 5,000 watts on June 16, 1954. WJPG was a
CONELRAD authorized radio station, meaning that if CONELRAD were activated, WJPG would remain on the air and transmit emergency information. A CONELRAD alarm was incorrectly sent to the WJPG control station on the evening of November 5, 1959. The message sent to the control station was "This is an air defense radio alert", rather than what should have been sent for a test, "This is an air defense line check." Northeast Wisconsin's three television stations (WFRV, WLUK, and WBAY) and radio stations WBAY and WJPG were all taken offline for 20 minutes as they prepared to implement CONELRAD alert procedures, until the error was realized and the alert preparation was reversed. WNFL changed ownership several times until 1996, when
Midwest Communications acquired the station, along with sister stations
WNCY and
WYDR (then WROE). On October 13, 2025, WNFL began simulcasting on
WDKF 99.7 FM Sturgeon Bay and rebranded as "99.7 & 101.9 WNFL". ==WNFL personalities==
