LimeSDR not receiver GNU Radio

I transmit a signal at a frequency of 433.075 Mhz (the spectrum analyzer is definitely transmitting), but it does not receive it, what should I do?

I presume you are transmitting carrier wave at 433.075MHz only with different device? Then your receive center should not be identical because in the middle of screen you will have bump (LO leakage). Change Center Freq in Soapy LimeSDR Source block.

Thank you!
