Hi Vule,
?
Raj has more experience with the uBitx than I do. However, the symptoms you describe indicate a stuck K1; here, the Nano is commanding the relay to be off, but the TX is still on and not indicated on the display.
?
You can try tapping K1 to see if that clears the TX before power cycling the radio.
