The "Winter Book" was partially 670 The Score since 104.3 tuned to simulcast the Score on February 2nd. So, thinking the move to FM for good book performance is somewhat over blown.
The last I checked the legacy 670 AM transmitter site on Army trail Road is still on the air. The move to the 1160 AM Des Plaines site appears to be taking longer than originally expected. Was the Army Trail Road site actually ever sold yet? Is the status of WLEY 107.9 and it's parent's bankruptcy filing effecting Audacy's sale of the Army Trail Road site? It appears that WLEY still has not filed for a new construction permit for a new transmitting site.
WYLL 1160 appears to be operating from their night site during the day for the last couple of weeks but, that was happening last summer in 2025 as well.
