Hi Erik

I slowly learn to treat the TinySA the right way.
One funny detail is that the vertical grid lines for the Log sweep show up when Center frequency is set to 0 and the span to max frequency.

The ini file need and update like Herb has pointed out as the Level per dB must be 32 and not 2 and Herb mention the -125 should be changed to -128 why I have not figured out.

Kind regards

Kurt
