Hello,
i'm using a ver. 4 Ubitx with 2.8 " Nextion display, using in CW there is a strange problem, something the radio it's "freezing" during trasmission and i can't send no more CW and also i can listen the sound of a strong MW transmitter near my house when it's making this problem. I have made a short youtube video with this strange thing:
Can be some RF getting into the Arduino Nano ??? Or the Diplay ??
