K-Line Firmware and Software

K3S High Performance Transceiver Firmware and Utility

Current K3, K3/0 Mini and K3s Production Firmware  

MCU 5.64 / DSP 2.88, 11-6-2018

All K3s radios ordered today will have Product Firmware loaded as they come out of the box.  Monitor the Elecraft Email Reflector where announcements are made when new releases become available.  

Elecraft delivers new features in firmware.  As a result, you should consider the Release Notes as an extension of the Owners Manual.  Documentation for the new features will be found there and will not appear in the Owner’s Manual until the next major manual revision is released.

Current Production Firmware Release Notes

  • RCV MODE "HI CUR" THRESHOLD CHANGED: The threshold at which "HI CUR" (excessive current drain) warnings appear in receive mode has been increased. Some users with all options enabled (including the sub receiver, internal transverter, and K-Pod) were seeing spurious HI-CUR warnings and disabling of one speaker channel.
  • KPA1500 ATU TUNE INTEGRATION: When used with a K3/K3S and the ACC cable, the KPA1500 completely controls ATU TUNE, requiring just a single switch tap. The amplifier automatically starts/stops TUNE mode at the K3. Use of the AUX cable between the amp and radio is also required to use this feature. 
  • See K3 Firmware Release Notes for complete revision history

 

Important - Please read before installing the latest Production Firmware

If you have firmware older than indicated below, please be sure to follow the steps below.

  • MCU 5.10 (or later): Re-run the 50-Watt gain calibration step on all bands one time. Once this has been done, there is no need to do it again when loading releases above 5.10.

Beta Firmware Installation and Release Notes

Beta Firmware Release Notes

No Beta Release available at this time 

Beta Test Firmware Installation Procedures


NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

A little more detail

We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this. Beta firmware means that, while the K3, K3/0 Mini, K3s engineering team has fully tested the firmware, it has not yet been deemed ready for Production status. You can always return to the last firmware you have downloaded by following the steps in the K3 Utility’s Help section.

To load Beta Firmware, follow the steps below:

    1.  Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

      2.  Now, we will download the firmware in Zip file format. In a web browser, type in this URL:  ftp://ftp.elecraft.com/K3/firmware/beta 

      If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on our browser to update your browser cache.    

        3.  Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

          4.  Unzip the files into the beta folder.

            5.  Enter the path to the beta folder in K3 Utility → Firmware tab → "Local folder for firmware files".

              6.  After you have made the change in Step 5, make sure you *DO NOT* check the K3 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                7.  Connect the K3, K3/0 Mini, K3s to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                  8.  Review the release notes. To find them, select the "Help" pull-down menu.

                    9.  Click "Send all firmware to K3." This will cause the firmware to be sent to the K3, K3/0 Mini, K3s. You will see that the K3, K3/0 Mini, K3s appears to restart itself. Monitor the Activity Log until it is complete.

                      10. After completing a new software download to your product, please power cycle the K3, K3/0 Mini, K3s OFF and then back ON before using it.

                       

                        Please report any new firmware issues to support@elecraft.com

                            P3 High Performance Panadapter Firmware and Utility

                            Current Production Firmware :  

                            MCU 1.60 / SVGA 1.34 / March 21, 2016

                            All P3 panadapters ordered today will have Production Firmware loaded as they come out of the box.  Monitor the Elecraft Email Reflector where announcements are made when new releases become available.

                            Current Production P3 Firmware Release Notes

                            • P3 commands in keyboard macros: Added support to allow P3 commands to be embedded in SVGA keyboard macros. When entering a keyboard macro using a USB keyboard attached to the P3/SVGA, P3 commands can now be intermixed with K3 commands by preceding the with the ‘#’ character. Example: set up a macro to set the K3 to PSK31, frequency 14.070, P3 span of 100 kHz, fixed tune enabled: FA00014070000;MD6;DT3;#SPN001000;#FXT1;
                            • SVGA keyboard macros as function keys: The first 8 SVGA keyboard macros can now be executed from the 8 front panel function keys. First, using a keyboard, program the macro and make sure to save it into one of the first 8 locations (mem 1 – 8). Then on the P3, press the MENU button and using the encoder, select the SVGA menu and press the encoder to enter. Then using the encoder, choose “Macro 1” through “Macro 8”, then press the function key (short tap or long hold) to map the macro to the function key.
                            • Enable/disable TX sensing at the TxMon coupler: Added TxSensEn to TxMon sub-menu. This allows enabling/disabling of transmit sensing at the coupler. For K3 and K3S users, TxSensEn can be set to “disabled”, which will use the serial connection from the K3 to determine the TX state. Setting TxSensEn to “enabled” will use forward power sensed at the TxMon coupler to determine TX state (useful for non-Elecraft radios).
                            • K3S attenuator support: The P3 now properly scales the display when the four-step attenuator in the K3S is enabled.
                            • SWR meter blanked: Both the analog and digital SWR displays are now blanked whenever the transmit power is too low to give a valid reading.
                            • New #RCF command: “Relative Center Frequency” applies an offset to the center frequency based on the passed argument. Usage: #RCFsnnnnnn; Where: ‘s’ is the sign + or -, nnnnnn is the offset in Hz. For example, if the P3 is set to a 30 kHz span and you would like to position the cursor on the left edge: #RCF+015000; Using #RCF without any arguments returns the difference in Hz between the center frequency and the vfo frequency.
                            • Serial #DSM command: The Display Mode (#DSM) command now controls the Transmit Monitor's power/SWR meter display as well as enabling and disabling the waterfall window. #DSM0 = Spectrum display only, #DSM1 = Spectrum + waterfall, #DSM2 = Spectrum + meters, #DSM3 = Spectrum + waterfall + meters.
                            • New #FON command: The display font can now be selected via a serial command. #FON0 = 5 x 7 pixels, #FON1 = 7 x 11 pixels, #FON2 = 9 x 14 pixels.
                            • New #XCV command: The transceiver type can now be selected via a serial command. #XCV00 = "K3", #XCV01 = User-defined, #XCV03 = 455 kHz IF, etc. The command uses the same number order as in the "Xcvr Sel" menu item.
                            • Transceiver definition bug fix - Exiting: When exiting the "Xcvr Def" menu page, if the user-defined transceiver is already selected, it will reflect the new values immediately, rather than having to re-select it.
                            • Transceiver definition bug fix - IF Invert: The USER transceiver that is defined in the "Xcvr Def" menu item may now specify "Not inverted" IF tuning even if the "K3" control language is selected.
                            • SVGA resolution / main waterfall bug fix: The main waterfall height had been switching to the default value after changing SVGA resolution.
                            • VFO B cursor = VFO DATA A bug: The VFO B cursor had been matching the VFO A cursor in DATA A mode, even when VFO B was in a different mode.
                            • Bitmap Upload bug: Fixes a bug in which the waterfall area was omitted from a bitmap capture when the TXMON meters were visible.

                            Important - Please read before installing the latest Production Firmware

                            • This P3 firmware requires K3K3S firmware version 4.25 or later to operate.

                            Beta Test Firmware Installation Procedures

                            NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                            A little more detail

                            We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this.  Beta firmware means that, while the P3 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status.   You can always return to the last firmware you have downloaded by following the steps in the P3 Utility’s Help section.

                            To Load Beta Firmware, follow the steps below:

                            1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility.  In this way, you can revert to the last Production firmware easily.

                            2. Now, we will download the firmware in Zip file format.  In a web browser, type in this URL:

                             ftp://ftp.elecraft.com/P3/firmware/beta/

                            If you do not see the correct version of the zip file, press the RELOAD / REFRESH button on your browser to update your browser cache.

                             

                            3. Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                            4. Unzip the files into the beta folder.

                            5. Enter the path to the beta folder in P3 Utility →  Firmware tab → "Local folder for firmware files".

                            6. After you have made the change in Step 5, make sure you *DO NOT* check the P3 Utility box titled "Copy new files from Elecraft server".  This will overwrite the Beta firmware if clicked.

                            7. Connect the P3 to your computer and be sure it is turned on.  Select the Firmware tab and Click on "Check versions now" button.

                            8. Review the release notes. To find them, select the "Help" pull-down menu.

                            9. Click "Send all firmware to P3."  This will cause the firmware to be sent to the K3S.  You will see that the P3 appears to restart itself.  Monitor the Activity Log until it is complete.

                            10. After completing a new software download to your product, please power cycle the P3 OFF and then back ON before using it.

                            11. Please report any new firmware issues to support@elecraft.com

                            Current Production Firmware Release Notes

                            • When ATU's frequency is set with F, FA, or MT commands, update TX frequency counter from the command rather than waiting for next transmission. Avoids switching to the ATU settings for the old TX count frequency on next TX before the TX frequency is counted.
                            • When Memory Recall Tune in Manual and Auto are off, don't retune on band switch frequency count.
                            • Add FCCS (Frequency Count Continuous Sample time) command to influence frequency counter inertia. Lower values cause the KAT500 to more quickly accept a new frequency count, higher values make the KAT500 less willing to move. This is likely to make the most difference in SSB.
                            • Use KAT500 command tester: FCCS; to query. FCCS nn; to set. Default is 12 msec.
                            • See KAT100 Firmware Release Notes for complete revision history

                             New Features

                            • Add UDP command server. Accepts just one KPA1500 command per input packet. UDP, TCP, USB Host and XCVR SERIAL HOST may operate concurrently. Only one TCP client may be connected, but several clients may use UDP.
                            • Add Tech mode XCVR SERIAL LOOP menu item and ^XL command for loopback diagnostic testing of 3.5mm XCVR SERIAL RS-232 port. See full release notes for details.
                            • Changed temperatures for fan speeds:
                              - On 160 thru 10 meters, fans increase speed at 50, 70, 80, 87, and 95 degrees, and slow at 40, 55, 75, 81, and 88 degrees.
                              - On 6 meters the fans increase speed at 40, 50, 65, 80, and 90 degrees and slow at 35, 41, 51, 66, and 81 degrees.
                              - New serial command ^FP0; can be entered in the KPA1500 Utility command tester to revert to previous fan profile, which sped up at 60, 70, 78, 85, and 90 degrees and slowed at 57, 67, 75, 82, and 87 degrees.  ^FP1; selects the "new" fan speed profile, ^FP0 selects the "old" fan speed profile.
                            • Add PEAK HOLD menu item and ^PH command. LED "power bar" peak hold time may be set between 0.1 and 9.9 seconds.
                            • CI-V support for older Icom transceivers that send "operating frequency" but not "TX frequency". KPA1500 may retune ATU on TX/RX transition if split is wide and ATU settings are different.
                            • Wake on LAN capability to switch amplifier on via Ethernet with a "magic packet" containing the KPA1500's MAC address. Tech mode NET WAKE on LAN menu item and ^WL command
                            • See KPA1500 Firmware Release Notes for complete revision history

                            • Add client host name to DHCP request packet, KPA1500_xxxx, where xxxx is the amp's serial number. This might be visible in some router's admin management pages.
                            • RADIO TYPE and XCVR SERIAL HOST can be changed without power cycle (TU N6TV)
                            • RADIO TYPE BCD shouldn't send AUXBUS messages (TU AC0C)
                            • Revert a change that broke FANticipator (TU K8UT)
                            • Improve power ON button handling
                            • Change ATU frequency from TX frequency even if TX frequency hasn't changed. XCVR frequency may have moved ATU.
                            • Ignore XCVR frequency changes when KEY IN is pulled down
                            • Change ATTEN RELEASE menu item from 1400-5000 ms to 1.4 to 5.0 seconds. Default unchanged from 3 seconds.
                            • Add intermittent tone alarm for "soft" (Overdrive) faults. ^SP command and ALARM TONE menu item choose between ALARM TONE OFF, steady tone for FAULT (the default), intermittent tone for OVR, or both.
                            • Write "soft fault" (overdrive) events to fault log
                            • Wake on LAN bug fix to improve reliability of KPA1500 Remote program's Power ON.
                            • Add tech mode VOLTS menu item to display the 5, 10, 12, -12, and 52 volt supply voltages
                            • Add ^EB command, e.g. ^EB 14125; to erase a single ATU bin (frequency segment) for the current antenna
                            • ^DF; without explicit frequency shows ATU settings for the current frequency
                            • Reset fault with Mode OPER button press
                            • ATU HiSWR retune rearranges ATU settings in the bin so most recently used setting is found first next time
                            • ATU memory searches full frequency range rather than just amateur bands (for MARS ops)
                            • Change fault text messages for 50V supply to 52V

                            No Beta Release available at this time 

                            Beta Test Firmware Installation Procedures

                            NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                            A little more detail

                            We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this. Beta firmware means that, while the KPA500 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status. You can always return to the last firmware you have downloaded by following the steps in the KPA1500 Utility’s Help section.

                            To load Beta Firmware, follow the steps below:

                            1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the KPA1500 Utility. In this way, you can revert to the last Production firmware easily.
                            2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL: ftp://ftp.elecraft.com/KPA1500/firmware/beta
                            If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on your browser to update your browser cache.

                            3. Right-click on the .zip file containing the beta firmware (e.g. KPA1500fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.
                            4. Unzip the files into the beta folder.
                            5. Enter the path to the beta folder in KPA1500 Utility → Firmware tab → "Local folder for firmware files".
                            6. After you have made the change in Step 5, make sure you *DO NOT* check the KPA1500 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.
                            7. Connect the KPA500 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.
                            8. Review the release notes. To find them, select the "Help" pull-down menu.
                            9. Click "Send all firmware to KPA1500." This will cause the firmware to be sent to the KPA1500. You will see that the KPA500 appears to restart itself. Monitor the Activity Log until it is complete.
                            10. After completing a new software download to your product, please power cycle the KPA1500 OFF and then back ON before using it.

                            Current Production Firmware Release Notes

                            • RCV MODE "HI CUR" THRESHOLD CHANGED: The threshold at which "HI CUR" (excessive current drain) warnings appear in receive mode has been increased. Some users with all options enabled (including the sub receiver, internal transverter, and K-Pod) were seeing spurious HI-CUR warnings and disabling of one speaker channel.
                            • KPA1500 ATU TUNE INTEGRATION: When used with a K3/K3S and the ACC cable, the KPA1500 completely controls ATU TUNE, requiring just a single switch tap. The amplifier automatically starts/stops TUNE mode at the K3. Use of the AUX cable between the amp and radio is also required to use this feature.

                                          7.  Connect the K3, K3/0 Mini, K3s to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                                            8.  Review the release notes. To find them, select the "Help" pull-down menu.

                                              9.  Click "Send all firmware to K3." This will cause the firmware to be sent to the K3, K3/0 Mini, K3s. You will see that the K3, K3/0 Mini, K3s appears to restart itself. Monitor the Activity Log until it is complete.

                                                10. After completing a new software download to your product, please power cycle the K3, K3/0 Mini, K3s OFF and then back ON before using it.

                                                      The following libraries and dependencies should be installed on your Linux distro:

                                                      GTK+ 2.8 or later, glibc-2.4, libstdc++.so.6 and cURL. 64-bit Linux requires 32-bit compatibility libraries.
                                                      Installing the FTDI driver

                                                      Follow this link to the FTDI Site for drivers: http://www.ftdichip.com/Drivers/VCP.htm

                                                      Depending on the Operating System you have, the driver needed for the Utility to communicate with the K-Pod will need to be loaded.

                                                      All Elecraft products in production use the FTDI chipset for this function. The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.

                                                      For the K-Pod, if your KUSB cable has a silver sheath on the wire, it is no longer supported. Elecraft recommends that a KUSB cable be purchased for full support.

                                                      Beta Test Firmware Installation Procedures

                                                      NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                                                      A little more detail

                                                      We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this. Beta firmware means that, while the K-Pod engineering team has fully tested the firmware, it has not yet been deemed ready for Production status. You can always return to the last firmware you have downloaded by following the steps in the K-Pod Utility’s Help section.

                                                      To load Beta Firmware, follow the steps below:

                                                      1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                      2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:

                                                      ftp://ftp.elecraft.com/K-Pod/firmware/beta

                                                      If you do not see the correct version of the zip file, press the RELOAD / REFRESH button on your browser to update your browser cache.

                                                      3. Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                                                      4. Unzip the files into the beta folder.

                                                      5. Enter the path to the beta folder in K-Pod Utility → Firmware tab → "Local folder for firmware files".

                                                      6. After you have made the change in Step 5, make sure you *DO NOT* check the K-Pod Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                      7. Connect the K-Pod to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                                                      8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                      9. Click "Send all firmware to K-Pod." This will cause the firmware to be sent to the K-Pod. You will see that the K-Pod appears to restart itself. Monitor the Activity Log until it is complete.

                                                      10. After completing a new software download to your product, please power cycle the K-Pod OFF and then back ON before using it.

                                                      11. Please report any new firmware issues to support@elecraft.com

The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.

                                                      Beta Test Firmware Installation Procedures

                                                      NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                                                      A little more detail

                                                      We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this.  Beta firmware means that, while the KX3 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status.   You can always return to the last firmware you have downloaded by following the steps in the KX3 Utility’s Help section.

                                                      To load Beta Firmware, follow the steps below:

                                                      1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                      2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:

                                                      ftp://ftp.elecraft.com/kx3/firmware/beta/

                                                      If you do not see the correct version of the zip file, press the RELOAD/REFRESH button onyour browser to update your browser cache.

                                                      3. Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                                                      4. Unzip the files into the beta folder.

                                                      5. Enter the path to the beta folder in KX3 Utility → Firmware tab → "Local folder for firmware files".

                                                      6. After you have made the change in Step 5, make sure you *DO NOT* check the KX3 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                      7. Connect the KX3 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                                                      8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                      9. Click "Send all firmware to KX3." This will cause the firmware to be sent to the KX3. You will see that the KX3 appears to restart itself. Monitor the Activity Log until it is complete.

                                                      10. After completing a new software download to your product, please power cycle the KX3 OFF and then back ON before using it.

                                                      11. Please report any new firmware issues to support@elecraft.com

                                                      Dependencies

                                                      The following libraries and dependencies should be installed on your Linux distro:

                                                      GTK+ 2.8 or later, glibc-2.4, libstdc++.so.6 and cURL. 64-bit Linux requires 32-bit compatibility libraries.

                                                      Installing the FTDI driver

                                                      Follow this link to the FTDI Site for drivers: http://www.ftdichip.com/Drivers/VCP.htm

                                                      Depending on the Operating System you have, the driver needed for the Utility to communicate with the K3/K3S will need to be loaded.

                                                      All Elecraft products in production use the FTDI chipset for this function. The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.

                                                      For K3, if your KUSB cable has a silver sheath on the wire, it is no longer supported.  Elecraft recommends that a KUSB cable be purchased for full support

                                                      Beta Test Firmware Installation Procedures

                                                      NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                                                      A little more detail

                                                      We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this.  Beta firmware means that, while the KXPA100 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status.   You can always return to the last firmware you have downloaded by following the steps in the KXPA100 Utility’s Help section.

                                                      To load Beta Firmware, follow the steps below:

                                                      1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                      2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:

                                                      ftp://ftp.elecraft.com/KXPA/firmware/beta/

                                                      If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on our browser to update your browser cache.

                                                       

                                                      3. Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                                                      4. Unzip the files into the beta folder.

                                                      5. Enter the path to the beta folder in KXPA100 Utility → Firmware tab → "Local folder for firmware files".

                                                      6. After you have made the change in Step 5, make sure you *DO NOT* check the KXPA100 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                      7. Connect the KXPA100 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button. 

                                                      8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                      9. Click "Send all firmware to KXPA100." This will cause the firmware to be sent to the KXPA100. You will see that the KXPA100 appears to restart itself. Monitor the Activity Log until it is complete.

                                                      10. After completing a new software download to your product, please power cycle the KXPA100 OFF and then back ON before using it.

                                                      11. Please report any new firmware issues to support@elecraft.com

                                                      Depending on the Operating System you have, the driver needed for the Utility to communicate with the PX3 will need to be loaded.

                                                      All Elecraft products in production use the FTDI chipset for this function. The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.

                                                      NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                                                      A little more detail

                                                      We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this.  Beta firmware means that, while the PX3 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status.   You can always return to the last firmware you have downloaded by following the steps in the PX3 Utility’s Help section.

                                                      To load Beta Firmware, follow the steps below:

                                                      1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                      2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:

                                                       ftp://ftp.elecraft.com/PX3/firmware/beta/

                                                      If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on our browser to update your browser cache.

                                                      3. Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                                                      4. Unzip the files into the beta folder.

                                                      5. Enter the path to the beta folder in PX3 Utility → Firmware tab → "Local folder for firmware files".

                                                      6. After you have made the change in Step 5, make sure you *DO NOT* check the PX3 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                      7. Connect the PX3 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button. 

                                                      8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                      9. Click "Send all firmware to PX3." This will cause the firmware to be sent to the PX3. You will see that the PX3 appears to restart itself. Monitor the Activity Log until it is complete.

                                                      10. After completing a new software download to your product, please power cycle the PX3 OFF and then back ON before using it.

                                                      11. Please report any new firmware issues to support@elecraft.com

                                                        5. Enter the path to the beta folder in K3 Utility → Firmware tab → "Local folder for firmware files".

                                                        6. After you have made the change in Step 5, make sure you *DO NOT* check the K3 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                        7. Connect the K3/K3S to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                                                        8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                        9. Click "Send all firmware to K3." This will cause the firmware to be sent to the K3S. You will see that the K3S appears to restart itself. Monitor the Activity Log until it is complete.

                                                        10. After completing a new software download to your product, please power cycle the K3 OFF and then back ON before using it.

                                                        11. Please report any new firmware issues to support@elecraft.com

                                                        W2 Firmware and Utility

                                                        W2 Current Production Firmware:

                                                        V1.00, 4-12-2010

                                                        All W2 SWR/Power meters ordered today will have Product Firmware loaded as they come out of the box. Monitor the Elecraft Email Reflector where announcements are made when new releases become available. 

                                                        Elecraft delivers new features in firmware. As a result, you should consider the Release Notes as an extension of the Owner's Manual. Documentation for the new features will be found there and will not appear in the Owner's Manual until the next major manual revision is released.

                                                        Current Production Firmware Release Notes

                                                        • SWR ACCURACY: As a result of our continuing product improvement, a different algorithm is now used to calculate the SWR value. Besides offering greater accuracy at lower power levels, the SWR data available from the Serial Port now reports the range of 1.00:1 to 99.99:1, giving much finer resolution of SWR readings.
                                                        • SWR ALARM CHANGES: The trip points for the SWR Alarm now match the SWR LED’s on the front panel of the W2. The range is still 1.1:1 to 5.0:1. Sending the W2 a “[” lowers the trip point, and “]” raises the trip point. Note the decimal point is implied in the serial response, i.e. “[25;” means the trip point was lowered to an SWR of 2.5:1 and “]40” means the trip point was raised to 4.0:1.
                                                        • SWR ALARM RESPONSE TIME: You can use the “PTT RY” RCA connectors on the back of the W2 to help protect your amp in case of high SWR. The response time that it takes for the relay to trip has been improved and can now catch an “I” sent at 60 WPM.
                                                        • SERIAL COMMAND CHANGES: The Serial Command set has had some minor changes in output format. 
                                                        • See W2 Firmware Release Notes for complete revision history

                                                            Beta Test Firmware Installation Procedures

                                                            NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.


                                                            A little more detail

                                                            We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this.  Beta firmware means that, while the W2 engineering team has fully tested the firmware, it has not yet been deemed ready for Production status.   You can always return to the last firmware you have downloaded by following the steps in the W2 Utility’s Help section.


                                                            To load Beta Firmware, follow the steps below:

                                                            1. Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                            2. Now, we will download the firmware in Zip file format. In a web browser, type in this URL:

                                                             ftp://ftp.elecraft.com/W2/firmware/beta

                                                            If you do not see the correct version of the zip file, press the RELOAD / REFRESH button on your browser to update your browser cache.

                                                            3. Right-click on the .zip file containing the beta firmware.  Save the file to your beta folder you just created.

                                                            4. Unzip the files into the beta folder.

                                                            5. Enter the path to the beta folder in W2 Utility → Firmware tab → "Local folder for firmware files".

                                                            6. After you have made the change in Step 5, make sure you *DO NOT* check the W2 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                            7. Connect the W2 to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button. 

                                                            8. Review the release notes. To find them, select the "Help" pull-down menu.

                                                            9. Click "Send all firmware to W2." This will cause the firmware to be sent to the W2. You will see that the W2 appears to restart itself. Monitor the Activity Log until it is complete.

                                                            10. After completing a new software download to your product, please power cycle the W2 OFF and then back ON before using it.

                                                            11. Please report any new firmware issues to support@elecraft.com

                                                            Elecraft delivers new features in firmware.  As a result, you should consider the Release Notes as an extension of the Owners Manual.  Documentation for the new features will be found there and will not appear in the Owner’s Manual until the next major manual revision is released.

                                                            Current Production Firmware Release Notes

                                                            • RCV MODE "HI CUR" THRESHOLD CHANGED: The threshold at which "HI CUR" (excessive current drain) warnings appear in receive mode has been increased. Some users with all options enabled (including the sub receiver, internal transverter, and K-Pod) were seeing spurious HI-CUR warnings and disabling of one speaker channel.
                                                            • KPA1500 ATU TUNE INTEGRATION: When used with a K3/K3S and the ACC cable, the KPA1500 completely controls ATU TUNE, requiring just a single switch tap. The amplifier automatically starts/stops TUNE mode at the K3. Use of the AUX cable between the amp and radio is also required to use this feature.

The FTDI driver allows your computer to create a virtual COM port so that the Utility can communicate with the Elecraft product.

                                                             

                                                            Beta Firmware Installation and Release Notes

                                                            Beta Firmware Release Notes

                                                            No Beta Release available at this time 

                                                            Beta Test Firmware Installation Procedures


                                                            NOTE: Beta test firmware may have new issues that we haven't caught during field testing. Please report them to support@elecraft.com.

                                                            A little more detail

                                                            We make it a little harder to load Beta firmware mainly because we want you to be sure you want to do this. Beta firmware means that, while the K3, K3/0 Mini, K3s engineering team has fully tested the firmware, it has not yet been deemed ready for Production status. You can always return to the last firmware you have downloaded by following the steps in the K3 Utility’s Help section.

                                                            To load Beta Firmware, follow the steps below:

                                                              1.  Create a new folder for the beta firmware on your Desktop or some other easily found location. Use the a different folder than the default folder found in the Firmware tab of the Utility. In this way, you can revert to the last Production firmware easily.

                                                                2.  Now, we will download the firmware in Zip file format. In a web browser, type in this URL:  ftp://ftp.elecraft.com/K3/firmware/beta 

                                                                If you do not see the correct version of the zip file, press the RELOAD/REFRESH button on our browser to update your browser cache.    

                                                                  3.  Right-click on the .zip file containing the beta firmware (e.g. k3fwXrYZ.zip for revision MCU X.YZ and all associated files). Save the file to your beta folder you just created.

                                                                    4.  Unzip the files into the beta folder.

                                                                      5.  Enter the path to the beta folder in K3 Utility → Firmware tab → "Local folder for firmware files".

                                                                        6.  After you have made the change in Step 5, make sure you *DO NOT* check the K3 Utility box titled "Copy new files from Elecraft server". This will overwrite the Beta firmware if clicked.

                                                                          7.  Connect the K3, K3/0 Mini, K3s to your computer and be sure it is turned on. Select the Firmware tab and Click on "Check versions now" button.

                                                                            8.  Review the release notes. To find them, select the "Help" pull-down menu.

                                                                              9.  Click "Send all firmware to K3." This will cause the firmware to be sent to the K3, K3/0 Mini, K3s. You will see that the K3, K3/0 Mini, K3s appears to restart itself. Monitor the Activity Log until it is complete.

                                                                                10. After completing a new software download to your product, please power cycle the K3, K3/0 Mini, K3s OFF and then back ON before using it.

                                                                                 

                                                                                  Please report any new firmware issues to support@elecraft.com
