# Manual File Transfer

If it is inconvenient for you to access the internet from the computer attached to your KX3, but you have access to another computer that can access the internet, you may update your KX3 firmware in two phases:

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.
2. Take the removable storage device to a computer that is connected to your KX3. Use the KX3 Utility to send firmware to your KX3.

An up-to-date KX3 Utility version may be required. If the internet-connected computer is some distance from your KX3, consider copying the current KX3 Utility setup program file to the removable storage device so that can be installed on the computer connected to your KX3.

#### Copying Files with an Internet Browser

- Start your favorite internet browser, such as Microsoft Internet Explorer or mozilla Firefox.
- Navigate to ftp://ftp.elecraft.com/KX3/firmware. The directory names are case-sensitive.
- Mount the removable storage device (plug the USB keychain drive into an available USB port).
- Create a new folder (mkdir \KX3Firmware) on the removable storage device.
- Copy all the files from the Elecraft FTP server KX3/firmware folder to the folder you created on the removable storage device. Some internet browsers permit you to select multiple file names and drag them to a Windows Explorer window opened to the target folder.
- Take the removable storage device to the computer that is connected to your KX3.
- Click Browse and navigate to the firmware folder on the removable storage drive.
- Send firmware from that folder.

#### Copying files with an FTP client

- Mount the removable storage device (plug the USB keychain drive into an available USB port).
- Create a new folder (mkdir \KX3Firmware) on the removable storage device.
- Navigate (cd \KX3Firmware) to that folder.
- Start the Windows FTP client program FTP.
- Open a connection to Elecraft's file server (open ftp.elecraft.com).
- Log in with user name anonymous. Use your e-mail address as the Password.
- Navigate to the KX3/firmware directory (cd KX3/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 as prompted. You need all the .hex files and ffwnotes.rtf.
- Close the FTP program (quit).
- List the directory (dir) of the new folder to verify that you have all the expected files.
- Take the removable storage device to the computer that is connected to your KX3.
- Click Browse and navigate to the firmware folder on the removable storage drive.
- Send firmware from that folder.
