[Solved via RMA] LimeSDR-Mini, Can't TX and QuickTest Fail, but I can pick up some things

Hi @jordan32710

I have got a similar problem with the loopback test failed. There is something damaged on the RF side or maybe the LMS7002.

Only -56 and -46dBs, must be more than -20.

Could you with LimeSuiteGUI run the FTT tool. Set up SXR Frequency at 100Mhz and run the FFT tool.
See mine below.

Do you have a signal at 100Mhz?

If you have a spectrum analyser could you connect the Lime RX to the spectrum analyser and check if you have some signal coming out?

I sent a similar post " Lime mini: RX issue with 100MHz and harmonics"
