Folder Location

Firmware files are copied from an Elecraft file server to a Local folder for firmware files (a file directory) on your Personal Computer before they are sent to your KH1. This section helps you choose the folder.

The KH1 Utility creates a Default folder for this purpose. You may choose another folder by typing or pasting its name into the Local folder for firmware files text box, or Browse for the folder.

Default

Navigate to the default folder for KH1 Firmware.

This folder is usually "c:\Users\username\AppData\Roaming\Elecraft\KH1 Firmware". On Windows XP this folder is usually "c:\Documents and Settings\username\Application Data\Elecraft\KH1 Firmware".

The AppData folder may be Hidden.

Browse

Navigate to your preferred folder, then click "OK".
