Winlink System Components

Client system
– Radio, computer with Winlink Express software, TNC (or sound card) and you, the end-user!


Radio Message Server (RMS)
– Radio gateway between the client (end-user) and the Winlink system backbone.


Common Message Servers (CMS)
– Winlink backbone.
             
  • Multiple CMS locations.       
  • Redundant, fault-tolerant
  • Located on 3 continents
  • One CMS is sufficient for normal system operation.

First Steps

Get a Winlink Account
:
  1. Download, install and configure Winlink Express (or other client program)
  2. Connect with the system (send a message) to create your account. Your radio email address is YOURCALL@winlink.org.
  3. Use the form (lower right) to have a password sent to your new address. Retrieve it using your client program.
  4. Use your callsign as your username, and password to log in here.

Winlink accounts stay alive only with radio use. Accounts off-air for 400 days are automatically purged. Use it or loose it!


Winlink Express Email Client

Winlink Express (formerly RMS Express) is the preferred Winlink radio email client because it supports all new system features, including the Winlink Hybrid Network and Secure Login to help prevent unauthorized access to your account.

Winlink Express

Setup your station

Winlink Express is designed to be easily used by single users with a single call sign but it may also be used to simultaneously send and receive mail with one or two tactical addresses or alternate Winlink accounts. It supports a wide selection of transceivers, TNCs and multimode controllers, the sound card modes WINMOR, Ardop, and VARA using virtual TNCs, HF Pactor, SCS Robust Packet, VHF/UHF AX.25 packet radio, and direct telnet to CMS servers or RMS Relay (for amateur radio High Speed Multimedia [HSMM], Broadband HamNet, D-Star DD mode, internet, and other TCP/IP networks).

The most common setup for ham radio operators is to use a PC or laptop, with the Winlink Express client installed, and a sound card interface such as a Signalink USB or Rigblaster, connected to your HF transceiver. This is familiar to anyone who uses narrow band or low-power digital modes with programs such as FLDigi or WSJT-X. See the diagram below:

There will be some additional setups required to get the program working correctly with your particular transceiver, interface, or TNC. To help you with these, visit Winlink.org, where you'll find links to various help blogs and discussion groups.

NH-ARES Winlink Exercise  / Test Plan

The NH-ARES exercise /test plan for 2018 will be a two part ongoing exercise and will focus on HF operations. The first part (Part A) will be the continuation of the monthly check-in session, broadcast on or about the first of the month; operators are requested to simply respond to a monthly broadcast currently administered by N5EI.

The second part (Part B) will be a quarterly P2P check in which operators are requested to make a connection to P2P host WQ2H, within a pre-determined or re-scheduled time slot, and download the quarterly test message. The time required for an operator to complete both of these tests is estimated to be about 5 minutes per month. While it’s understood that all operator cannot make all check-ins, it is recommended that each operator complete as many test sessions as feasible. Statistics will be complied, presented, and utilized to hopefully improve and streamline the 2019 plan.
