 # Main features:
- - OneOfEleven mods, including AM fix
+* many of OneOfEleven mods:
- - fagci spectrum analyzer (**F+5** to turn on)
+   * AM fix, huge improvement in reception quality
- - better battery percentage calculation (based on real measurement, battery calibration recommended)
+   * longpress buttons functions replicating F+ action
- - battery calibration option available available in the menu (instructions below)
+   * fast scanning
+   * channel name editing in the menu
+   * channel name + frequency display option
+   * shortcut for scannlist assignment (longpress `5 NOAA`)
+   * scannlist toggle (longpress `* Scan` while scanning)
+   * configurable button function selectable from menu
+   * battery percentage/voltage on status bar, selectable from menu
+   * longer backlight times
+   * mic bar
+   * RSSI s-meter
+   * more frequency steps
+   * squelch more sensitive
+* fagci spectrum analyzer (**F+5** to turn on)
+* some other mods introduced by me:
+   * SSB demodulation (adopted from fagci)
+   * backlight dimming
+   * battery voltage callibration from menu
+   * better battery percentage calculation, selectable for 1600mAh or 2200mAh
+   * more configurable button functions
+   * longpress MENU as another configurable button
+   * better DCS/CTCSS scanning in the menu (`* SCAN` while in RX DCS/CTCSS menu item)
+   * Piotr022 s-meter style
+   * restore initial freq/channel when scanning stopped with EXIT, remember last found transmission with MENU button
+   * reordered and renamed menu entries
+   * LCD interference crash fix

-❗❗❗You can now calibrate the battery voltage reading in the radio menu.

-<img src="images/batcal.jpg" width=300 />
-
-To enter the calibration:
-
-1. turn the radio on while holding PTT and the first side button 
-2. go to BATCAL option and adjust the voltage with UP/DOWN buttons
-3. confirm the setting, calibration will be saved to EEPROM

-# New/modified function keys
-
-* Long-press 'M' .. Copy selected channel into same VFO, then switch VFO to frequency mode
-*
-* Long-press '7' .. Toggle selected channel scanlist setting .. if VOX  is disabled in Makefile
-* or
-* Long-press '5' .. Toggle selected channel scanlist setting .. if NOAA is disabled in Makefile
-*
-* Long-press '*' .. Start scanning, then toggles the scanning between scanlists 1, 2 or ALL channels
-
-# Some changes made from the Quansheng firmware
-
-* Various Quansheng firmware bugs fixed
-* Added new bugs
-* Mic menu includes max gain possible
-* AM RX everywhere (left the TX as is)
-* An attempt to improve the AM RX audio (demodulator getting saturated/overloaded in Quansheng firmware)
-* keypad-5/NOAA button now toggles scanlist-1 on/off for current channel when held down - IF NOAA not used
-* Better backlight times (inc always on)
-* Live DTMF decoder option, though the decoder needs some coeff tuning changes to decode other radios it seems
-* Various menu re-wordings (trying to reduce 'WTH does that mean ?')
-* ..
