  • Notes
  •  
    This CN-597 Crystal Receiver was very similar to the NESCO CN-113 and covered the frequency range of 300 to 2,500 meters. The telephone terminals on the CN 113 were replaced by a telephone jack on the CN 597. The set included a built-in crystal detector.  Binding post connections were also provided to allow it to be used with an external vacuum tube detector in a regenerative circuit or with an alternate crystal detector.  The switch in the center determined whether the crystal detector (the "DET" position) or the vacuum tube ("AUD" position) would be used.
