LimeSDR Mini bug?

Hello,

I have a big problem with a LimeSDR Mini and I can not find what’s wrong if you have ideas to dig I’m interested.

I have a bandpass filter in the middle of the screen and nothing happens.

Regardless of the display frequency, I have the hole in the middle.
With SDR Console (V3) or HDSDR, it’s the same thing.

I tried a calibration that reused but it does not matter or I miss something …

No problem with the RTL dongle.

Thank you for your help.
