VARA

Created by EA5HVK, the Vara suite is a series of weak signal transmission modes. VaraC uses these in their suite and this is an option in the WinLink express software. Please note that while free, to use the full speed of the software you need a license.

VaraHF can be used to send to a gateway or point-to-point. It can use 500Hz and still deliver a fast response. When you go to pick a site, you will have the option of updating the propagation forecast, allowing you to pick the gateway based on both bandwidth and your best chance of sending a message.

In the Vara family are Vara FM and Vara Sat for handling comms for FM or satellite. He also has a Chat and Terminal application.

If you are looking for a fast transmission or just to check out the options, visit the Vara Modem page. I have used it in both the free and paid versions, and the speed difference is noticeable between the two, but just having the propagation is a good reason to check out this software.

    DigiPi Review
