Hi Jeff,

Not sure which version board you have, but could it be usb/lsb related (despite the 160m absence which I presume was in LSB)?

If it is, I would look at the Arduino clock issue which I suspect should only affects V3 and V4 boards (V5 has a different 2nd IF frequency). 

I have a few post on this subject in this forum.
