 Toward the end of 1926 ownership of WIBM was transferred to C. L. Carrell of Chicago, Illinois, joining a roster of seven portable stations operated by Carrell.However, due to the difficulty of regulating "moving targets", in May 1927 the newly formed Federal Radio Commission warned that it would soon stop licensing portable facilities.Facing deletion, Carrell arranged for the station to be permanently moved to Jackson, Michigan.
