Edit Configuration

Enable Antennas

Enable Antennas may be used to select antenna connectors available for each band. Disabled antennas are skipped when the KXPA100 ANT button is held. At least one antenna connector must be enabled for each band. Each column has an "All Bands" check box at the top to enable or disable an antenna for all bands.

Click "Apply" or "OK" to save the revised configuration in your KXPA100.

Enable Antennas is available with KXPA100 firmware revision 01.18 and later.

Save Configuration

Click to show a "Save As" dialog where you may provide the name of a new file that will receive configuration data. A suggested file name is generated from the KXPA100's serial number and the local date and time, but you may overtype this with any valid file name. Click "Save" to begin saving configuration data.

The KXPA Utility creates a folder intended for configuration files, located under the current user's Application Data folder. You can locate the current user's Application Data folder by entering "cd %APPDATA%" from a Windows command prompt.

You may use this folder, or use the Save As dialog to navigate to a different folder for saving configuration files.

The configuration file contains data such as the fault table, per-band settings, and all ATU memories. If you plan to reset the antenna tuner to its factory condition or erase antenna tuner memories, consider saving a copy of the configuration first.

Firmware is not preserved in the saved configuration file.

Restore Configuration

Click to show a File Open dialog. Select an appropriate configuration file and click "Open". Your amplifier's configuration will be restored from the selected file.

The KXPA100's serial number and fault table are not restored.

The configuration file includes factory-computed unit-specific calibration data, and a configuration file saved from one KXPA100 may not be restored into another.

Do not modify the configuration file between Save and Restore, or Restore may fail.

Display Fault Table

The Fault Table shows your amplifier's most recent 256 faults, with the most recent fault entry first.

Each line has:

Fault Codes
Code Caption Description Detail data
N NO FAULT Not a fault Number of times KXPA100 turned on since last fault
A NO MATCH Antenna tuner was unable to find a match for the antenna's impedance SWR
C HI CURRENT PA drain current exceeds the permitted limit Amperes
D HI DISSIPATION PA is dissipating too much power (as heat). Dissipated power is input supply voltage times PA drain current less output power. Watts
H HI SUPPLY VOLTAGE Input DC supply voltage exceeds the allowed maximum Volts
L LO SUPPLY VOLTAGE Input DC supply voltage is lower than the allowed minimum Volts
P HI FORWARD POWER RF output (forward) power exceeds the permitted maximum Watts
R HI REFLECTED POWER RF reflected (reverse) power exceeds the permitted maximum Watts
S HI SWR Antenna SWR exceeds the permitted maximum and ATU is absent or in a mode that does not permit auto tuning SWR
T HI TEMPERATURE PA Heat sink temperature exceeds allowed limit Degrees C

The fault log is included in the saved configuration, and Elecraft product support may request a copy of your KXPA100 configuration file to analyze its fault table and configuration.

Erase Antenna Tuner Memories

Click to show an Erase Memory dialog. Select the desired band (or all Bands), and then click "Antenna 1" or "Antenna 2" to erase memories for one Antenna.

Click one Antenna button and then the other to erase memories for both antenna connectors on the selected Band(s).

Reset Configuration

Click to show a Reset Configuration dialog. Click "Reset Configuration" to clear the KXPA100 to its factory-fresh configuration. This erases all antenna tuner memories and restores all configuration settings to the factory default values. The microcontroller resets as part of this operation and the LEDs may blink briefly.

The RS-232 serial port speed is reset to 38,400 bit/s; you may need to use the Port Tab's Test Communications button to re-establish communications with the KXPA Utility if the serial port speed changes.
