Winlink
From Wikipedia, the free encyclopedia
Winlink, also known as the Winlink 2000 Network, is a worldwide radio messaging system that mixes internet technology and appropriate amateur radio technologies. The system provides email with attachments, position reporting, graphic and text weather bulletins, and emergency communications between internet users and the amateur radio, US Army and Air Force MARS (Military Affiliate Radio System), and UK Cadet Forces communities. In the UK amateur radio frequencies must not be used for 3rd-party communications, so only amateur-to-amateur messages are allowed and communications between (non-radio amateur) users on the internet and UK radio amateurs on the amateur bands - even in most emergency situations - is illegal. This same restriction applies in other European states.

[edit] Interference caused by WinLink stations
WinLink has the potential to cause interference to other communications, particularly HF packet radio. Radio Amateurs have organized groups such as Winlink Watch to document and publicize such interference.
[edit] Openness
WinLink is partially encumbered by commercial technology that is not completely open. It may be more properly thought of as a product than a protocol. See PACTOR.
