All Just to confirm that PowerSDR is the latest 2234 version downloaded with all the attendant files from the SVN today. I edited the initozy11.bat to reflect my current firmware Merc 3.1 Pen 1.6 and Oz 2.1. Rx going nicely. The ANF sounds much better when selected with no observed distortion. Shel CT1IZU 1346707982.0
