Winlink is...

...a worldwide radio email service that uses radio pathways where the internet is not present, and is capable of operating completely without the internet--automatically--using smart-network radio relays. Winlink provides its users email with attachments, position reporting, weather and information bulletins, and is well-known for its role in emergency and disaster relief communications. Licensed Winlink operators/stations use both amateur radio and government radio frequencies worldwide. The system is built, operated and administered entirely by licensed volunteers. Support for the system is provided by the Amateur Radio Safety Foundation, Inc., a US 501(c)(3) non-profit, public-benefit entity. (

The State of Texas Emergency Management has accepted and made part of its SOP to use Winlink as a secondary means of communication.  The ARES and Rapid Response Task Force (RRTF) regularily perform Simulated Emergency Tests (SETs) to train and exercise their equipment.

Winlink may be performed on VHF, UHF, and HF through the use of TNCs, sound cards, signal processors, and radios.  This form of communication is much slower than commercial communication, but is reliable when regular communications need to be replaced or supplemented.
