FlexRadio Announces the Immediate Availability of SmartSDR v4.2.20

Tim - W4TME

FlexRadio is pleased to announce the release of SmartSDR v4.2.20, now available for download.

SmartSDR Basic™ and SmartSDR+™ v4.2.20 is a SmartSDR+ Feature Access software and firmware release for Aurora™, FLEX-8000™, and FLEX-6000™ series SDRs, as well as Maestro™. This version supersedes all previous SmartSDR releases and is available to all users. Access to new features in this release is available to all SmartSDR+ feature license holders.
We recommend upgrading to v4.2.20 at your earliest convenience. Reverting to earlier SmartSDR v4 versions is discouraged, as older releases may reintroduce issues resolved in this update and cause issues with installed drivers.

VERY IMPORTANT: Before upgrading, please review the SmartSDR v4.2.20 Release Notes for important release-specific information.

VERY IMPORTANT: If you are not running SmartSDR v4.2.18, it is highly recommended to uninstall all previous versions of SmartSDR before upgrading to SmartSDR v4.2.20. If you are running SmartSDR v4.2.18, skip this notice. Before installing SmartSDR v4.2.20, it is strongly recommended that all previous versions of SmartSDR be completely uninstalled from your PC, including DAX and the FlexVSP driver. SmartSDR v4.2.18 introduces a new software architecture that includes updated DAX and FlexVSP drivers. Retaining older versions on your system may result in installation conflicts or degraded performance. For best results, ensure all earlier SmartSDR versions (v4.1.5 and below) are fully removed before proceeding with the installation. Refer to the HelpDesk article “How to Install SmartSDR v4.2.18” for detailed uninstallation and installation instructions. Just bear in mind that you will be substituting v4.2.20 for v4.2.18

Release Highlights for SmartSDR+ v4.2.20

SMART-205: Band Plan/Band Edge Markers: SmartSDR now includes an integrated band plan display feature that provides a visual, color-coded representation of amateur radio frequency allocations based on IARU regional standards.

SMART-11334: User Configurable RX Filters: SmartSDR now includes mode-specific, user configurable receive filters, allowing operators to tailor receiver bandwidth characteristics independently for each operating mode.

SMART-12046: Display TX Filter on Panadapter: SmartSDR now includes an optional feature that displays the transmit filter bandwidth directly on the panadapter, with an additional on-screen overlay indicator. This allows for real-time tracking of transmit filter bandwidth changes as mode or bandwidth settings are adjusted.
