WIFR-LD

Gray Television sold WIFR's spectrum in the Federal Communications Commission (FCC)'s incentive auction for $50,060,965; at the time, the station indicated that it planned to enter into a post-auction channel sharing agreement.[2] On April 21, 2017, Gray requested special temporary authority to move the license of W22EE-D (channel 22), a low-power station it owns in Rockford, to channel 41 with the intent of using it to maintain CBS service in the market; in its request, Gray disclosed that the full-power WIFR license would be surrendered on May 31, 2017, though WIFR's existing transmitter would be still be used, but with its power restricted to meet the transmitting requirements for W22EE-D.[3][4] The full-power license was cancelled on that date.[5] Gray had acquired W22EE-D from DTV America in an eight-station deal in 2016; it had never commenced any previous on-air operations since the call letters were issued on May 17, 2011, nor constructed any facilities.[6]

On November 18, 2019, WIFR-LD attempted a transfer to its post-reallocation channel 28 from a temporary lower-power antenna lower on their transmitter tower, but moved back to 41 in a matter of days with the permission of T-Mobile, which will eventually hold that spectrum. This is due to channel 28 also being allocated to the northwest in Milwaukee to full-power ABC affiliate WISN-TV and causing cross-channel interference in portions of Boone and McHenry counties. The station again transitioned to channel 28 permanently on January 15, 2020, this time arranging with Weigel Broadcasting to simulcast 23.1 over their low-power station in the market, WFBN-LD (channel 35) as subchannel 23.11 to address those over-the-air viewers experiencing interference from WISN-TV. Gray expects to transition to their regular higher-power signal at the former position of the channel 41 antenna in the spring.[1]

WIFR shut down its analog signal, over UHF channel 23, at noon on February 17, 2009, the original target date in which full-power television stations in the United States were to transition from analog to digital broadcasts under federal mandate (which was later pushed back to June 12, 2009). The station's digital signal remained on its pre-transition UHF channel 41.[8][9] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 23.
