VARA HF 4.0 is a major upgrade that offers additional speed, robustness and utility, including a new robust 500 Hz narrow bandwidth mode.
The Winlink Team has planned a careful network cutover to this new version on June 30, 2020, because it does not offer backwards compatibility with earlier versions. RMS running VARA HF 4.0 will not communicate with VARA 3-equipped clients.
A VARA HF 4.0 upgrade package is available now for early download at:
To avoid early incompatibilities this package will not allow installation and use until June 30. This delay is to allow critical information to flow about the upcoming breaking change, and to allow users who intend to be offline on the cutover date to download it now for installation on or after June 30.
