As Bob mentions there may be more to it then just nailing that particular command. But worth taking a look after I deal with the wwvb psk issue. As far as the 5 to 3 V I would just use a 3 term reg like the cherry semi chip. But there are plenty of alternates. It will take 5 in and give 3.3 out at plenty of current. I think the discussions useful as to exactly what the correct new rvcr would be that is available and for $5. ;-) Regards Paul
