Has anyone built Ashhar's Specan?

Craig Wadsworth <cwadsworth@...>

I'm preparing to build the spectrum analyzer board designed by Ashhar Farhan.  See this link if you are not familiar with the Specan:
If I understood Ashhar correctly, a spectrum analyzer will be needed to balance the uBitX's output amplifiers. Building a working, legal, uBitX is my primary goal.  Building a working Specan would be part of the journey to a uBitX.  What has been your experience?  Comments? Advice? (Constructive) criticism?
Thanks and regards,
