As part of our ongoing software release process, we periodically review the versions of SmartSDR available on the Maestro and M-model radios’ Select a Version screen.

With the release of SmartSDR v4.2.18 on April 28, 2026, the following older versions will be removed from the version selection list on June 26, 2026:

  • 4.1.3
  • 3.10.10
  • 3.9.19
  • 3.9.18
  • 3.8.23
  • 3.7.4
  • 2.12.1
  • 2.10.1

For all Maestro and M-model radios, if you have not upgraded to SmartSDR v4.2.18 before June 26, 2026, those older versions will no longer be available after the device is rebooted.

If you are operating a remote station and cannot perform a firmware upgrade remotely, and your radio is currently running one of the versions listed above, please make arrangements to upgrade your system before this date to avoid any disruption in operation.
