      The upper and lower signal bracket lines are designed to lie on the
      center of tone position of the highest and lowest tone respectively
      (closer to 1780 Hz). The 2000 is an indicator of the full 3 dB
      bandwidth of the 16 tones. You should always specify the center
      frequency when specifying a QSO frequency. Other modem programs
      (MultiPsk, DM780 etc) may show the 3 dB boundaries.
