DDUtil Setup

  • On the Setup form Amps tab in the KPA1500 group select the serial port for the amp.
    • Note: the amplifier has an internal USB to Serial adapter built in and will create a serial port when the USB cable is attached from the PC to the amp. However, this port number needs to be checked as Windows may create a duplicate port of an already existing port. This is a long-standing defect in Windows and must be corrected by re-assigning the port number to one that is not already in use. To correct this condition follow these steps:
      • Open the Windows Device Manager and select Ports (COM & LPT).
      • Find the newly created port and right=click it and select properties.
      • On the Properties form select the Advanced button and select a unique port number.
      • Hit the OK button two times to complete the operation.

Operation

  • The controls listed above, for the most part, are a mirror of the front panel controls on the amplifier.
  • It is suggested that the operator become familiar with the Elecraft KPA1500 Users Manual especially the ATU section.
