There are two orange wires in the supplied wiring harnesses that connect to the Raduino.
One of the orange wires goes to pin 15 of the connector labeled "OSCILLATORS" in the schematic,
this wire should be connected to +12v as shown in the wireup diagram.
The other orange wire goes to pin 5 of the connector labeled "CONTROLS" in the schematic,
this wire goes directly into the A3 pin of the Mega328p on the Arduino Nano processor.
The schematic is here: ?http://www.hfsigs.com/bitx40v3_circuit.html
The wireup instructions are here: ?http://www.hfsigs.com/bitx40v3_wireup.html
Sometimes shorting a Mega328p pin to 12v (such as the A3 pin) only blows the IO cell for that pin,
but since nothing works at all anymore it seems you have blown the processor and it must be replaced.
You might try buying a new Arduino Nano processor board off the web (perhaps $4 USD),
but installing that on the Raduino board will require removing the 30 soldered pins of the blown Nano first.
You might buy a new Arduino Nano plus one of the Si5351 breakout boards and a 2x16 display, create your own Raduino.
Neither of these will be trivial to do if you are not experienced with this sort of thing.
Perhaps I am wrong and someone will have a suggestion for an easy fix.
But I think your easiest solution is to buy a new Raduino from HFSigs.

For a mistake, I've connected one of the orange wire that came from the Arduino Nano to the power supply, so Arduino dont't never works.
Can you help me?
I need the program in Arduino Nano, so I can substitute it (Arduino with a new one), in this way my BITX 40 can works again because it works really well, is a greate trasceiver and its very useful for portable use.
