Re: LimeSDR Noise Spike

When making a screenshot, it is desirable to avoid cutting anything off. In your case you have trimmed off the outer edges of the SDRC window to show only what you think is important. The bottom edge of the window includes useful status and the top and sides often contain settings. Knowledge of this information is often critical to reproducing or otherwise figuring out what is going on. So, if you use the screenshot tool (the little camera icon) in SDRC you will always get a full capture. Do not edit it and always attach it as a file instead of embedding it so that the tiny text is legible.

It’s nothing more than a screen shot taken of what I saw after adjusting the gain settings and calibrating. No evasive editing whatsoever. What “material data” are you looking for. I can generate more of these if there is something specific you would like to see.
