Firmware

This page is used to obtain firmware files from Elecraft, display the firmware versions currently installed in your K3, and to send firmware to your K3.

Folder Location

Firmware files are copied from an Elecraft file server to a firmware folder (a file directory) on your computer before they are sent to the K3. This section helps you choose the folder on your computer to store firmware files.

The K3 Utility creates a folder for this purpose.

On Mac OS X - the default folder location is:
Volume:Users:User:Library:Application Support:Elecraft:K3 Firmware:

On Linux - the default folder location is:
/USER$/Elecraft/K3_Firmware/

Default

Click to navigate to the K3 Utility's default folder for K3 Firmware.

Browse...

Click to start a Browse for Folder dialog. Navigate to the folder of your choice and then click "OK".

Check for New Files

Elecraft makes new K3 firmware available by placing files on an Elecraft-provided file server. The K3 Utility program uses the File Transfer Protocol (FTP) to copy new firmware files from Elecraft to the folder you have selected on your computer.

Your computer must be connected to the internet to use this K3 Utility function. See the Manual File Transfer section for a technique to update K3 firmware when your computer is not connected to the internet.

Copy new files from Elecraft server into local folder

When this check box is selected, the Check Versions Now button copies the latest firmware files from the Elecraft file server to your firmware folder.

Check Versions Now

Click to compare the firmware versions installed in your K3 with the most recent firmware available in your folder. If the Copy new files from Elecraft server into local folder check box is selected, the copy is performed before comparing versions.

Check Versions every 6 hours

When selected, the K3 Utility periodically compares firmware versions and informs you if a new firmware version becomes available. The Copy new files from Elecraft server into local folder check box should be selected to use this option effectively. You may Check Versions at any time by clicking Check Versions Now.
