The SNR units should be standardized into a single metric, something 
actually useful like ESNO or db. If that isn't available then we should 
aim to eyeball / manually calibrate impossible boards against known 
reliable demods on the same feed, it should be close enough.

This requires patience and time from the right people with the right
