    I seem to remember this being some sort of bizarre copy protection
scheme -- the DAT will refuse to record unless there are frequencies
in this notch, and commercial stuff will be distributed with those
frequencies cut out. It sounds too stupid to be true, but I've heard this
several places (now including the net). Real flat response, uh huh ...
