<DIV>The snubbing diode is D1 on sheet one. K1 is powered off 3P3VA
so we don't <BR>have to bring the digital 3.3v line near the front end. I expect
you can <BR>guess how we found that out!<BR><BR>In which case one end of
D1 should be returned to 3P3VA rather than 3P3VD. I <BR>see that we have it
connected to 3P3VD on Mercury so perhaps best to leave <BR>as is.<BR><BR>Also
pin 1 on U50 and U51 should be connected to ground.<BR><BR>L3 should be
connected to 3P3VD.<BR><BR>Any more feedback before Tony starts the PCB
layout?<BR><BR>73's Phil ....VK6APH</DIV></BODY></HTML>
