Xiegu have released a new firmware, I have it here: https://drive.google.com/file/d/1Migt0oaKqmdex93P_YmAM5b4YmGMOALI/view?usp=sharing

SHA256: B5B32930627C1AC98C428ADB2C5AA228DDCD65FAFA73942F65C3CA840EB992D7
App: V1.1.4 Feb 16 2022,17:15:50
1. Add FFT peak hold switch, GEN > DISPLAY SETTING > FFT PK HOLD
2. Fix bug "Gate Way" can't save in "WLAN" setting page
3. Change rx volume from 0-50 to 0-55(5dB more than prev version)
4. Change CW decoder's threshold to a higher level(better robustness but needs higher SNR)
5. Calibrate the RX S-Meter giving more accuracy
6. Add ALC level indicator(at the top-right of the bandscope area, below the tx power strings)
7. Optimize the Fw flashing logic(base board will boot-up itself after flashed the Fw)
Base: V1.1.4 Feb 15 2022,13:19:59
1. Fix bug built-in MIC feedback to speaker sometimes
2. Fix bug base board some times not booting at power on
3. Optimize ALC algorithm
4. Optimize SWR algorithm, less jumping around
5. Optimize switching power synchronization algorithm, less birdies
Tips:
☆ ALC tricks
a) ALC level equ to 0: over driving, decrease input signal level
b) ALC level equ to 100: under driving, increase input signal level
c) When doing Digi,the audio baseband signals are almost constant amplitude,
adjust the soundcard volume to make ALC level between 20-80 to get good linearity
Enjoy... Gaz
