Gr-limesdr bug

I am testing the newly implemented gr-limesdr source.

But I found some problems.

  1. the 2 receiving channels can’t output the same signal as LimeSuite does.
    This is the screen shot when I am receiving same signal using 2 receiving channels in LimeSuiteGUI’s fft viewer (18.01 phase alignment branch).

Then I created a simple flowgraph using gr-limesdr as the source.

This is the output of the frequency sink when there is no signal ( it’s already different)

This is another output of the frequency sink when I was transmitting an FM signal on that band.

  1. another problem is when I switched the calibration to ON. There will always be a insufficient gain problem. But if I do the calibration in LimeSuite, there is no this kind of problem.
