LimeSDR mini poor performance

Hi

I have a new LimeSDR mini and my tests was very poor

First I need to set the gain above 50db to get good calibration, otherwise I get MCU 5 error

FM tx runs very poor (2mts max … with hackrf I can receive signal in all of my home 3 rooms away)

When I test GPS Spoof like GPS fake out project whit the @cswiger grc (at 30db gain both TX and RX) he upload a picture of a FFT plot transmitting at -64db and me setting gain to 60 I only see -70db

Also if I ran LimeUtil --timing I get lot of errors

lot of this:

Timing tuning operations:
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(100 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(101 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(102 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(103 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(104 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)
SetFrequencyCGEN(105 MHz) failed
TuneVCO(CGEN) - failed to lock (cmphl!=0)

lot of this:

CGEN PLL tuning: 19.2089 ms
SetFrequencySXT(100 MHz) - cannot deliver frequency
SetFrequencySXT(101 MHz) - cannot deliver frequency
SetFrequencySXT(102 MHz) - cannot deliver frequency

SetFrequencySXT(107 MHz) - cannot deliver frequency
SetFrequencySXT(108 MHz) - cannot deliver frequency
SetFrequencySXT(109 MHz) - cannot deliver frequency
SetFrequencySXT(110 MHz) - cannot deliver frequency

also

Is my board faulty ?

Thank you

=> Board tests PASSED <=

Elapsed time: 2.62 seconds

So, I assume that is normal this behavior, only TX at 50-60 db, the errors in the command and also high heating after 10 minutes of use
