   Changes

   [Wi-Fi] – Optimized operating logic on the Wi-Fi settings page – Added HELP guidance within the Wi-Fi settings interface

   [AGC]

   – Adjusted AGC algorithm for improved signal-to-noise ratio (SNR)

   [RADIO SETTING1]

   – Renamed menu items 1 and 2 to AGC ​SLOW and AGC FAST – AGC values now represent time constants in milliseconds (ms) – Usage notes:

   • AM / SSB voice: AGC SLOW provides smoother audio
   • CW: AGC FAST improves signal detail and readability [Spectrum] – Added cursor mode for spectrum display operation – Cursor mode activation:
   • Set CENTER MODE to OFF in RADIO SETTING1
   • Use frequency wheel to align cursor with the desired signal – Operational tips:
   • Moving the cursor farther from the zero point improves SNR
   • Interference av​oidance method:

   – Shift tuned frequency to move the interference point – Align cursor with the desired signal to avoid interference Important Notes – A factory reset is REQUIRED after upgrading – Skipping the reset may result in:

   • Incorrect band data
   • Inability to switch bands
   • Frequency display showing 0

   V1.1.7 Release Note Image File SHA256: BF153B10AB3D942060E65BE35A64A2D6C419A5EFF8D941E5C8CE93CE6DD44305 APP: V1.1.7 Jul 26 2023,11:50:55 BASE: V1.1.6 Mar 7 2023,09:57:03 NOTICE: Consider this version experimental! For normal use we recommend version 1.1.6.

   1. Added wfview server to enable support for wfview, see included ‘x6100 wfserver.pdf’ file for setup instructions. wfview is a free and open source program that allows many modern Icom ham radio transceivers (such as the Xiegu X6100, IC-7300, IC-9700, IC-7610, IC-R8600, the IC-705, and many others) to be controlled via a computer. wfview shows the gorgeous spectrum display on what​ever display is connected, including projectors, touch screens, and TVs. wfview allows for full radio (remote) control from a computer keyboard and basic control from a numeric keypad. wfview can run on hardware ranging from the $35 Raspberry Pi to laptops to desktops. wfview runs on recent versions of Linux, macOS, and Windows. wfview supports rig control over ethernet/wifi as well as over the traditional USB serial CIV bus. wfview also allows older radios to be accessed over the internet, for full control and low-latency audio streaming.

   More information about wfview is found at wfview.org .

   Tips & Note: #### The X6100 internal WiFi antenna is only usable when adjacent to the access point.

   Consistent performance is achieved by connecting a wired USB-C LAN dongle to the HOST connector using a LAN cable between the radio and access point.

   Always read the enclosed update log!

   ATTENTION: If you have firmware older than the previous January 17 update, please see the below information regarding the battery management update;

   1. The built-in battery gauge is enabled to manage the battery cell. After the upgrade, the battery voltage will no longer be used as the management data, but the battery capacity measured by the battery gauge will be used as the management data. The relevant precautions are as follows:

   1.1 After updating the firmware, please perform 4 full charge and full discharge cycles in a row, after which the fuel gauge will measure accurately.

   Just after updating the firmware, before the 4 times of charge and discharge are completed, the displayed power error is large, so don’t pay attention to it.

   The charging process should be kept as continuous as possible until the charging instruction is completed, which is conducive to the accurate capacity​ determination of the fuel gauge. 1.2 The updated charging indicator status is as follows: Blinking: Indicates charging Steady on: Indicates that charging is complete Off: When the charging option is turned off in the menu, the indicator light will not be on. 1.3 After the update, when the power is lower than 10%, the battery symbol shows red and the interior is empty, and the device will automatically shut down. 1.4 The battery voltage is no longer used as the basis for the judgment of low battery.

   Jan 25 2022 important update with correction to 6m transmit frequency range (50-54 MHz) and change of low-battery shutdown level to ​prevent low voltage shutdown when battery gauge has not been calibrated.

   App: Version V1.1.3 Jan 15 2022,14:48:38 Correct the problem of wrong frequency division of 6m (original division: 50.1M~54.0M, modified to: 50.0M~54.0M) The conditions of low-battery shutdown are modified to: battery <10% and voltage lower than 7.3V to prevent low-battery shutdown by mistake when the fuel gauge is not calibrated.

   Base: Version number V1.1.3 Jan 25 2022,14:21:03 Fix the problem that the RTS signal of the CI-V/CAT port could not control the CW transmission ⇒ Xiegu X6100 Firmware Update v1.1.3 (2022-01-25) Always read the enclosed update log!
