      You need 9 or 10 kc bandwidth for receiving commercial drm on short and
      mediumwave ... with a center of 12kc ....

      You switch the rig to am or fm (what gives you the widest filters) ... grab
      the last 455kc if and downmix it with 467kc (or 443) to 12kc .... feed that
      in the soundcard and hear errorfree music *g* (with the right software)
