I do not seem to have that option for recalibration. I'm on version 1.09 of Dr Lee's software.
However, Allison was right on . I recalibrated a couple of times and receive has returned and transmitting about 5 watts.
Thanks for straightening me out before I ripped the unit apart.
Has any one had trouble with the Nextion screen going off after a while?
After about 2-3 minutes, the screen goes dark. Sometimes if I immediately turn the encoder , it comes back on,
but some time I have to reboot.
