Hello everyone, I have a uBITX20 V6 to which I installed the Display Nextion Base with FW KD8CEC V1.2 Hex Nextion. I find myself in the situation where the RF output power on all bands is 10W, except for the 40m band where it reaches 20W. The SSB and CW modulation is full and when receiving on another RX it is distorted. The trimmers for adjusting the Bias of the RF Finals are set as set by HF Signals. In fact, the original RF Power on artificial load was about 8W on 80 and 40m, and then decreased on the higher Bands up to about 3-4W on 10m. I guess now the levels of the three oscillators are too high. The HEX file doesn't allow me to see where to vary the four output possibilities of the Raduino (2/4/6/8mA). I have the CEC source files, but I don't have knowledge of programming with Arduino, from which to establish that the Display is Nextion and change these outputs; to then have the compiled hex file to be loaded on the Arduino Nano. Can any of you help me on this?
Thank you.
