    * `ENABLE_ADJUSTABLE_RX_GAIN_SETTINGS` keeps the rx gain settings set in spectrum mode after exit (otherwise these are always overwritten to default value), this makes much more sense considering that we have a radio with user adjustable gain so why not use it to adjust to current radio conditions, maximum gain allows to greatly increase reception in scan memory channels mode (in this configuration default gain settings are only set at boot and when exiting AM modulation mode to set it to sane value after am fix)
    * `ENABLE_SPECTRUM_CHANNEL_SCAN` this enables spectrum channel scan mode (enter by going into memory mode and press F+5, this allows SUPER fast channel scanning (4.5x faster than regular scanning), regular scan of 200 memory channels takes roughly 18 seconds, spectrum memory scan takes roughly 4 seconds, if you have less channels stored i.e 50 - the spectrum memory scan will take only **1 second**
    * `VOXSen` fixed and improved VOX sensitivity setting from menu. Added `VoxDel` - VOX delay setting allowing to set value to `0` for no VOX delay which might be useful for packet radio enthusiasts (APRS etc.).
+   * Fixed AM AGC so **AM demodulation is crystal clear**, no audible clicks, no need for `AM_FIX`.
 
  ## Keyboard shortcuts
 * In `VFO mode` long press `5` to enter `scan range mode`
