Ham radio specialists are famous for doing the coolest things. They help transmit television signals and communicate with people around the world using handheld transceivers. Another thing HAMS engages in is transfer emails on ham radio through a system called Winlink.

This system is one of the best assets in amateur radio communications tools during emergencies or otherwise. In this article, we are going to take you through some of the basic workings of Winlink. Read on to know more.

So What is Winlink?

Winlink Global Radio Email or Winlink is a messaging system operating worldwide through amateur radio frequencies. It also employs government frequencies to enable the sending of emails automatically without using the internet. HAM radios can thus come in use when the regular systems are out of function at times of emergencies.

Emails sent through Winlink can incorporate attachments while also providing position reporting, for instance, Automatic Position Reporting Services. It also transfers messages, relief communication, weather updates along with information bulletins. The people operating Winlink have to sign up for this service and operate under the system set by volunteers in HAM.

How Does it Work?

Winlink utilizes an HF network from around the globe that is found virtually everywhere on the planet. Winlink email messages can be transmitted within the network for endpoint transmission by attaching a single sideband (SSB) radio to a device with specialized with a modem and software interface.

It also offers independent parallel radio email programs for the United States Department of Homeland Security SHARES (SHAred RESources) HF network and Military Affiliate Radio System among various other users.

Specific HF, UHF, and VHF systems are configured to connect all over the Winlink network. Winlink emails are transferred between the internet and hams through Gateway stations.

General Rules of Winlink

There are general rules that govern the use of Winkink over various frequencies. It goes without saying that you are not allowed to encrypt messages and send obscene or business messages.

The service is mostly in use by hams who access WINMOR or PACTOR digital mode through the HF radio via their packet on UHF or VHF frequencies. When using these, you can access the simple packet terminal node controller from a relay station.


For a long time now, Winlink has provided radio pathways for emails, even where the internet is not present. With the help of Ham volunteers, smart network radio relays have been brought into use through an automatic transmission. A truly astounding discovery- there’s so much to Winlink that we cannot cover it in just one guide. Stay tuned for more!
