That's odd, the orange wire on my Ubitx is the input to the audio amp, the wire colours and positions on the socket is the same as in the wire-up but the orange wire definitely goes to the TDA2822 pin 7, there's also a C78 connected to pin 7 that's not on the schematic.? The (full) audio feed is on the yellow wire, an oscilloscope confirms this. The orange wire need a DC path to ground for the TDA2822 to function correctly.? It seems there's an error on the wire-up drawing.
