Questions:\r
-1. SM1000 designed to be operated with 6-16V power supply. Would should recommend 9-15V. Should we recommend PS? Many will operate at 13.8V(rig supply). Do we risk ground loops, etc. using rig supply?\r
-2. Should C37, C39, C40 be 50V? Or, only caps connected to VIN?\r
-3. Are you going to supply speaker? Need J4?\r

+ DR 29 Sep 2014: tested with IC7200 at full power using same\r
+ 12V battery as SM1000. No problems observed, so I think we\r
