This page is used to save and restore your K3's configuration data, and to view or set up the K3's Crystal Filter Configuration.
The K3 has a number of configuration menu items that are reset to their default values during the "Parameter Initialization" process (EE INIT) described in the Troubleshooting section of the Elecraft K3 Owner's Manual. You may find it convenient to save the original configuration settings before performing this procedure and then restore the configuration settings after Parameter Initialization.
General configuration parameters, which include option module enables, crystal filter setups, transmit calibration data, and other menu settings; and control settings (last-used selections for switches, knobs, VFOs, etc.)
These settings are not saved, and they are not generally disturbed by the Parameter Initialization procedure (EE INIT):
Click to show a "Save As" dialog where you may provide the name of a new file that will receive K3 configuration data. A suggested file name is derived from the date and time, but you may overtype this with any valid file name. Click "Save" to begin saving configuration data from your K3. This process takes from 30 seconds to a couple of minutes, depending on the K3's CONFIG:RS-232 speed setting.
Click to show a File Open dialog. Select the configuration file of your choice and click "Open". Your K3's configuration will be restored from the file you have selected.
Do not modify the configuration file between Save and Restore, or Restore may fail. If you wish to create a configuration file that contains a different configuration, use the K3's CONFIG menu to make changes, and then use Save K3 Configuration As to save the new configuration.
Click to show the Crystal Filter Configuration dialog, used to view or set up the crystal roofing filters in your K3.
Click to start the Transmitter Gain Calibration wizard, used to automate the Transmitter Gain Calibration procedure described in the K3 Owner's Manual.
The automated Transmitter Gain Calibration procedure uses K3 commands introduced in MCU Firmware revision 2.45. The button is disabled if an earlier MCU firmware version is installed.
Click to show a "Power On Banner" dialog where you may provide a short (22-character) message that will be displayed on the K3 display during its power-up sequence. The display appears with MCU firmware revision 2.77 and later.
