FlexRadio Systems announces the immediate availability of SmartSDR v2.7.3.

The SmartSDR v2.7.3 software release greatly improves the stability and reliability of your FLEX-6000 software defined radio. Once SmartSDR v2.7.3 is installed, FlexRadio strongly recommends not reverting to any previous versions of SmartSDR v2 to ensure the optimal user experience.

SmartSDR 2.7.3 can be downloaded from the FlexRadio Systems website. SmartSDR v2.7.3 is a general release containing software bug fixes and new features for version 2 of SmartSDR for Windows, SmartSDR for Maestro, SmartSDR for M models, SmartSDR CAT, and DAX. 

Please download and review the SmartSDR v2.7.3 Release Notes included with the release package before installing SmartSDR v2.7.3 on your FLEX-6000.

CAUTION: If upgrading from SmartSDR v2.6.2 or below, this release of SmartSDR will result in two firmware update processes occurring on the FLEX-6000. The radio’s LED indicator will turn purple twice and the radio will reboot after each firmware update. Due to a software change that is specific for M model radios, the firmware upgrade may hang after the 2nd time the power button LED turns purple which will require resetting the radio as described in the Best Practices for Installing a New Version of SmartSDR for Windows section below. 

If you are updating a remote radio using a VPN, having the ability to turn off and on the DC power supply and being able to reboot the radio using the REM ON connector should be a prerequisite before upgrading the FLEX-6000.

FLEXVSP NOTE: If upgrading from SmartSDR 2.6.2 or below, this version of SmartSDR will update the FlexVSP driver. The SmartSDR installation software will automatically remove the previous FlexVSP driver and install the new one. Please reboot your PC when prompted at the end of the SmartSDR v2.7.3 installation process to ensure the FlexVSP driver is installed correctly. The new FlexVSP driver is not backward compatible with previous versions of SmartSDR CAT. An unhandled exception error will occur when using previous versions of SmartSDR with the new FlexVSP driver.
