Just to make sure I have thus straight: You do these steps three times, one at each power level for REFL and then, after reversing connections, 3 more times for FWD at each power level - right? When you do the Errata #5 - do you leave the cables where they were - in FWD position - or go back to REFL position - before you set resistance at pin 5? Thanks folks, 73/Tim
