I have been using this firmware ( https://www.dropbox.com/s/0fgdya5k2qrmsnu/binary20200717.bin?dl=1 ) on my V2, and have been very favorably impressed.
Smaller frequency steps above 140MHz: 6kHz at 4GHz, 3kHz at 2GHz, ......, about 400Hz at 150MHz (Factory firmware had 12kHz steps)
Interpolation of calibration, auto startup with Cal 0
Adjustable bandwidth from 3kHz down to 10Hz
Display color control
The only feature I would really like to see added is true CW generation.
