You are right, Allison-san.
There should be a possibility of lower spurs on uBitx.
Thank you for letting me know it.

Hiro san,
The NCO (form of synthesis) is very clean save for harmonics due to square waveform.
However there are three oscillators and mixers and the resulting combines can and do
create spurs.
