The problem is that there is no change between 500/400 Hz or between
250/200 Hz. That means it is not possible to determine if a 400 Hz
or 200 Hz filter are selected only from the filter width display.
In the case where the "FLn" icons are too small to be read with one's
distance lenses and the radio is too far away for the reading lenses
the filter width display should be an important clue to the selected
filter.
