SmartSDR v0.13.10 is now available for download for use with your FLEX-6700 and FLEX-6500 Signature Series SDR.

Please follow the upgrade procedure below as there is a new version of SmartSDR CAT included with SmartSDR for Windows v0.13.10. Installing SmartSDR for Windows no longer installs SmartSDR CAT automatically due to a virtual com port driver dependency that requires SmartSDR CAT to be uninstalled and the PC rebooted before a new SmartSDR CAT can be installed. Therefore please follow the upgrade procedure listed below to ensure a trouble free upgrade to the latest version of SmartSDR for Windows.

If additional information is needed, several of the procedures described below are outlined in greater detail in the SmartSDR v0.13.10 Release Notes. After installing SmartSDR for Windows on your PC, make sure you review the Release Notes before updating the FLEX-6000 radio software and SmartSDR CAT.

2.) If SmartSDR CAT is running, close it too.
3.) Power cycle the FLEX-6000 by pressing the front panel power button, waiting several seconds and then pressing it again to reboot the radio. Wait until the radio has finished booting before continuing.
4.) Run the SmartSDR v0.13.10 Installer. (SmartSDR_v0.13.10_Installer.exe)
5.) At the end of the installation process, display the release notes (A PDF reader is required) and run SmartSDR for Windows.
6.) You should see your FLEX-6000 in the chooser indicating that an upgrade is required.
