Upload compiled github version and name it as 0.8.4.5
Found bug (AIC datasheet very poor) on CH1 (search why H version work better on 0.8.4.3 on CH1 measure) update github code
For better CH1 measure good set 10Hz bandwidth and made full calibration.
My H4 allow measure on ~ -35dB in 2.4-2.7GHz range
About Brightness, i remember about this option, but Ken, AA6LK:
One of the new feature of the H4 is the LCD brightness adjustment. However, the current numeric pad entry method is not intuitive, so I have been thinking of changing it to sliding bar display and use jog switch left and right to change birghtness between 25% (DAC=800) and 100% (DAC=3300). So I think I'd better add my change based on yours.
I upload code and think soon this feature will be added
