Each Christmas they ran a drive for Children's Hospital which involved the radio programming coming from the front window of one of the large department stores. The public was activly involved inthe programming and so had to be able to hear and talk with the djs. The frequency shifter was the only practical way to stop the feedback problem with the man on the street. Keith Bauer White Tiger Racing
