File – Filename: x6100udimg-251213001.zip – SHA256: 47d136b51d6077c1b138e029e800dcb20386a6bf45d80b72805e32c1e91fcaa9

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
