[1] WZSK was last owned and operated by New Millennium Communications Group, Inc.[4] 1040 AM is a United States clear-channel frequency, on which WHO is the dominant Class A station.

WZSK was required to leave the air during nighttime hours in order to prevent interference to the skywave signal of WHO.

The station first operated at a Federal Communications Commission (FCC) assigned frequency of 1050 kHz, with a maximum output power of 250 watts.

In 2010, New Millennium Communications Group applied for Special Temporary Authority (STA) for WZSK to operate at reduced power due to technical problems with the station's aging transmitter.

On March 26, 2021, the FCC informed New Millennium Communications Group in writing that a complaint had been filed by an individual in October 2020 claiming that the station had been silent for more than a year.

New Millennium Communications Group President Shane Imler responded to FCC attorney Victoria McCauley in correspondence dated June 8, 2021.

FCC officials responded in its final correspondence of November 18, 2021 that Imler's letter failed to address proof of the station's operation as previously requested.
