@Zack , if that’s quicker or easier, I may give you access to the PC via Teamviewer. Just tell me.

@Zack, @andrewback,
Is this an issue with the Lime stack, or could it be the board itself which is defective? Both USB LimeSDR were received 15 days ago or so, and it’s weird that one behaves so differently. If that’s hardware issue, how should I proceed to ask for a replacement?

Hi @ChrisLM,

Sorry for a late response. Contact Crowd Suplly for replacement, please.
