Controlling an External Modem

WinWarbler can decode and generate CW, RTTY, and other digital modes via an External Modem connected to a serial port. WinWarbler interacts with a connected External Modem by sending it individual commands, e.g. Initialize or begin transmitting or switch to RTTY. The individual commands required for a particular model of External Modem are obtained from an External Modem Command File. WinWarbler includes External Modem Command Files for the KAM 98, MFJ 464, PK232, PK900, and PTC-IIe; you can [http://www.dxlabsuite.com/winwarbler/Help/RTTYModemCommandFiles.htm create an External Modem Control File] for other devices.

Required Connections

To control an External Modem, you will need

  • an RS-232 cable connecting a serial port on your PC with the External Modem's serial port
  • an audio cable connecting your transceiver's audio output to your External Modem's audio input
  • an audio cable connecting your External Modem's audio output to your transceiver's audio input
  • a wire connecting your External Modem's PTT output to your transceiver's PTT input; PTT is an abbreviation for [:PTT:Push To Talk]

  • to transmit RTTY in FSK, a wire connecting your External Modem's RTTY output to your transceiver's RTTY input
  • to transmit CW, a wire connecting your External modem's CW output with your transceiver's CW input

All of the above connections should be described in detail in your External Modem's user guide.
