What's in this update

MCU 1.41 / DSP 1.13

  • AF GAIN SMOOTHER AT LOW END: The AF gain control now has finer gra​nularity at the low end. To accommodate this , the gain range is now 0-60 (was 0-40).
  • INTERNAL SPEAKER BEHAVIOR IMPROVED: (1) Fixed bug that caused audio output mute/unmute cycling on strong signals. (2) Gain distribution changed to reduce speaker overdrive condition related to CODEC output. (3) Audio EQ optimized for speaker.
  • FM DEVIATION AND FM MIC GAIN SETTING BEHAVIOR CORRECTED.
  • NEW LED BRT MENU ENTRY: Applies to ​the TX, delta F, OFS, and VFO B LEDS (not the LCD backlight). Allows brightness of these LEDs to be adjusted, but only in the case where the LCD backlight is off. During adjustment of LED brightness, the LCD backlight will automatically be turned off if it was on, then turned back on when the menu is exited.
