Got it working, tapped in just after c106 and used the ground for the missing variable cap. I'm still working on getting it tuned up. Its off frequency and not sure why. I'm using this formula to tune, clk0 is the bfo.
void setFrequency(unsigned long f){
? if (isUSB){
? ? si5351.set_freq((usb_bfo_freq - f) * 100ULL, SI5351_CLK2);
? ? si5351.set_freq((usb_bfo_freq) * 100ULL, SI5351_CLK0);
? }
? else{
? ? si5351.set_freq((bfo_freq - f) * 100ULL, SI5351_CLK2);
? ? si5351.set_freq((bfo_freq) * 100ULL, SI5351_CLK0);
? }
? frequency = f;
}
Added a pic where I attached a mini coax to go to the raduino
