Manual File Transfer

If it is inconvenient for you to access the internet from the computer attached to your K3, but you have access to another computer that can access the internet, you may update your K3 firmware through a two-step process:

1. Use an internet browser or FTP client program to copy firmware files from Elecraft's file server to a removable storage device such as a USB keychain flash memory device or a floppy diskette.
2. Insert the removable storage device into the computer that is connected to the K3. Use the Browse button to navigate to the removable storage media, and change your firmware Folder to the appropriate folder on the removable storage device. Update firmware from that folder.

An up-to-date K3 Utility version may be required to load new firmware. If the internet-connected computer is not conveniently close to the K3, consider copying the current K3 Utility to the removable storage device so that it is available to be installed on the computer used to load firmware into the K3.

Copying files with an Internet Browser

• Start your favorite internet browser, such as Microsoft Internet Explorer or mozilla Firefox.
• Navigate to this URL: ftp://ftp.elecraft.com/K3/firmware. The directory names (K3/firmware) are case-sensitive.
• Mount the removable storage device (plug the USB keychain drive into an available USB port).
• Copy all the files in the specified file folder to the removable storage device. Some internet browsers permit you to select multiple file names and drag them to an Explorer window opened to the removable device.

Copying files with an FTP client

• Create a Folder on the removable storage device.
• Change Directory (cd /d) to make that folder the current directory.
• Start the FTP client program. The FTP client's program name is often "FTP".
• Open an FTP connection to Elecraft's FTP server (open ftp.elecraft.com).
• Log in with user name anonymous. Use your e-mail address as the Password.
• Navigate to the K3/firmware directory (cd K3/firmware). The names are case-sensitive.
• List all the items in that directory (dir).
• Specify binary transfer mode (bin).
• Get all the files (mget *). Reply "Y" or "N" as prompted. You need all the .HEX files and the hfwnotes.rtf file.
• Close the FTP program (quit).
• List the directory (dir) of the removable storage device to verify that you have all the expected files.
