Winlink 2000 ( is a world wide system that connects packet radio to internet e-mail.

The system is comprised of the following parts:

  • Client: a packet radio station that sends and receives e-mails using specialized software and a standard amateur radio packet setup.
  • Gateway: a specialized packet setup that is connected to the internet. It connects the client to the internet and transfers e-mails to and from the client.
  • CMS (common message server): Web servers run by the Winlink administrators that move e-mails between the gateway stations and the internet.

Winlink can operate in a number of modes on HF, VHF and UHF. These include:

  • Packet (AX.25 protocol) on UHF and VHF
  • Pactor 1, 2, 3 and 4 on HF
  • WINMOR: A new digital mode for HF utilizing sound card to radio interface. An inexpensive substitute for Pactor.
  • Telnet: Direct access to the Winlink system from a computer attached to the internet.

How to get involved:

In order to participate in Winlink you will need to set up a client station. The easiest, and least expensive is a VHF station utilizing existing hardware.

  • VHF radio capable of operation on 144.950 MHz
  • A computer running Windows XP or newer. There is a team working on a Linux client but it is recommended to start with a Windows based system.
  • A copy of the Winlink client (user) software package installed on the computer.
    • A list is available here:
    • RMS Express is recommended. it is inclusive, not requiring a separate e-mail client, and is easy to use.

  • With a TNC
    • It is important to have a TNC that is supported by the client software that you intend to use. Each software has its own list.
    • TNCs compatable with RMS Expreess are listed in the sidebar.
    • Other client software apps have their own list of supported TNCs.
  • Without a TNC
    • You can work WinLink (or any other packet system) without a TNC.
    • Read Elmer’s tutorial (Here)
    • Or go to the source: AGW Exxpress web page
    • One easy install. Works with most PSK type soundcard interfaces.
    • No TNC needed to create a WinLink e-mail client.


  • Connect the TNC to the radio following the manufacture’s instructions.
  • Kenwwod TS-2000 menu setup to run RMS Express:
    • 47: DATA TRANSFER RATE; BUILT-IN TNC “1200bps”
    • ?
  • USB / Serial dongles work very well when your computer does not have a serial port.
