If you have recompiled the firmware, what Si5351 routines are you using?
I suspect the code that the Easy Bitx build instructions point to is using the etherkit Arduino library,
though this is not clearly stated.? Also, there have been a number of changes to the
etherkit library over the years, so getting the correct version number is important.
If you are using firmware that you have compiled from source,
this library version issue is my best guess as to what your problem is.

I still suspect firmware.
Other possible causes might be:
? A short between BFO and VFO wires out of the Si5351, but that should be fairly obvious on the scope.
? An error inside the Si5351, but that seems unlikely
I doubt it is an error on the i2c bus into the Si5351, if that was the case it wouldn't work at all.
