Winlink – One of the most amazing things in ham

radio

Winlink is not just a program, it is an incredible system for sending messages around the world via both radio and the Internet. Look at the diagram. Suppose I (W8ERD) wish to send a message to K8MP via radio. First, I need to choose one of the Radio Message Server (RMS) stations to send it to. Fortunately, the Central Message Server will send me an updated list of the RMS stations that I am most likely to be able to contact, based on the distance, frequency, and current propagation conditions. Let’s suppose it is KB3PCY, on 3593.5 kHz. So, I call him, he answers, and my message is automatically sent to him. Then he sends it automatically to the Central Message Server (CMS) via the Internet, which then sends it automatically via the Internet to ALL the RMS stations, where it waits for K8MP to retrieve it. Sometime later, K8MP checks to see if he has any incoming messages. He goes thru the exact same process, and chooses W0VG to connect to. W0VG then automatically sends my message to him. and then automatically notifies the CMS that the message has been delivered. The CMS then notifies all The RMS stations via the Internet to delete the message. Now is that cool or what? Whoever designed this really knew what they were doing. Winlink is so good that non-ham organizations have their own systems. such as government stations, and ships at sea. You might say that everything depends on the CMS and the Internet to work, so it is not completely dependable. The CMS is a very heavily fortified station, with multiple backups etc. And the system can operate in a radio-only mode if necessary. If all else fails, or you don’t want to go thru the system, there is also the Point-to-Point mode. In that case you can send messages directly to the other station, assuming they are within range. Or you can avoid radio completely and send your message via Telnet, which uses only the Internet. That would be the case, for example, of KE8IZX on the diagram who does not have radio winlink capability yet. She can still send and receive messages that use the radio capability of winlink.
