To add the function button, look on this webpage https://github.com/amunters/bitx40 where it says:
"v1.07 Added functionality via the Function Button: Use a pusbutton to momentarily ground pin A3 (orange wire). Do NOT install an external pull-up restistor!"
The Raduino schematic on this webpage: http://www.hfsigs.com/bitx40v3_circuit.html shows that A3 from the Nano goes to pin 5 of the 8 pin connector. So the function switch should be wired between that orange wire coming from pin 5 of the Raduino's 8 pin connector and ground. (The tuning pot is wired to pins 1,3,4 of that same 8 pin connector.) The solid copper plane on the back of the Raduino is ground, you could just solder a wire to one of the mounting holes at a corner of the Raduino, run that wire to the other side of the new function switch.
