System Requirements

EchoLink is designed to work on personal computers meeting the following minimum requirements:

  • Intel Pentium (or compatible) CPU, 133 MHz or higher.  The program has been tested successfully on a 486DX4 at 75 MHz, but a 133-MHz Pentium is strongly recommended as a minimum system.
  • Any of the following Microsoft Windows versions:
    • Windows 95 (Winsock 2 and Internet Explorer 4.0 or above also required)
    • Windows 98
    • Windows 98, Second Edition
    • Windows Me
    • Windows NT 4.0 (Workstation or Server), Service Pack 3 or higher
    • Windows 2000 (Professional, Server, or Advanced Server)
    • Windows XP
  • Color display with resolution of 800x600 or higher.  The program will work with 640x480 resolution, but with diminished usability.
  • 8- or 16-bit sound card or built-in sound hardware, with appropriate Windows drivers.  Full-duplex capability is required for Sysop mode.
  • Dial-up or dedicated Internet connection, 24 kbps or higher in each direction.  128 kbps upstream (ISDN, cable modem, DSL or better) is recommended for Conferencing capability..
  • Approximately 5 MB free disk space.
  • Sufficient RAM to meet the minimum operating-system requirements, plus approximately 8 MB (the amount of RAM used by EchoLink).
  • Mouse, or other pointing device (recommended).
  • Microphone and speakers, for Single-User mode.
  • ASCII or direct-serial rig interface, for Sysop mode.  (For more information, see Interfacing.)
  • Packet terminal-node controller (TNC), for APRS option in Sysop mode.  The TNC serial port must run at 9600 bps.  Although it is believed to work with most TNCs, only the AEA PK-232 has been tested with EchoLink.
