  3. As described in the installation instructions, download to your computer the Radioditty official firmware (GD-77 Firmware V4.3.6 [Ham Version]).
  4. Unzip the downloaded zip archive, then copy, somewhere on your hardrive (e.g. " My Documents "), the file GD-77_V4.3.6.sgl, located in " Firmware software V4.3.6\ " sub-directory.
