I used to work for Gray Sound and Communications Systems in Pittsburgh
back in the early seventies where we used a frequency shifter for
radio station KDKA.  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.
