Hello everyone, i am a new uBitx user, I have built uBitx v5 and loaded CEC firmware for Nextion 3.2 inch display. Moreover, I have incorporated a second Arduino Nano to use it as a . I have gone through Ian's (KD8CEC) instructions to enable I2C S-meter and so on and what I see on the display is according to those instructions. The question is: Do I have to calibrate the I2C S-meter in some way, e.g. using a signal generator and applying -73 dBm (S9) to the antenna port of the uBitx? Has any of you done such a thing before?
