well it's great that you mentioned that - I THINK I spotted a ZENER instead of a 1N4148 at D3.... though it's a bit hard to tell them apart... Perhaps a ZENER got into my signal diode drawer somehow (understandable!) .. although it didnt' make much of a difference in the end result... so i'm just circuit tracing around now - one WEIRD thing i noticed is that the ground plane of the top of the board is not connected to the ground plane of the bottom (apparently by design?) - odd... on the other side of the board it's connected to CN10's +5V pin....
