Sure, I know Jim beat me but he's young..  Of course we were both waiting for the filter loading/saving scripts to get fixed.  In the end, Jim fixed them.

Anyway, I got the controller on HAM4 now too.  Attached are two plots of calibrated spectra, top from 23 Sept with the Level1 controllers and the lower from this afternoon with the Level3 controllers.  Certainly compromises in place but good between 1 & 10 hz.   I'll look for the plotting tool jim used to compare to HAM3.
