Re: xtal issues?

The fact that the odd behavior is on the high side is a clue. That's where you're passing through the parallel resonance of the crystal. The only things that pop to mind right away are drive level and sweep speed. Any chance the drive level might be too high? I think the level is adjustable in the Midnight SNA. Pretty sure Dave has the sweep speed set in firmware appropriately for crystals

If you haven't already,you might also pose the question over on the SNA group to see if it's been observed by other NAT/SNA users.
