I noticed that LimeSuiteCalibrate is missing on my 64bit arm install …

I was trying to see why this error is occuring but not on my 32bit install – both are Ubuntu16 and both were updated with in a week or less of each other … Updated/built/installed SoapySDR then LimeSuite …

Did you try with --start 30000000 ? You can’t calibrate below 30 Mhz.

LimeSuiteCalibrate is still missing …

As for limesuite --cal. Why would you not calibrate @ the lowest frequency you intend to use? Limitation of rx is not limited to the Lo generator … ie 30mhz-28mhz for I/Q calibration of rx 2mhz. Or is the limesuite --cal only for DC offset and not for phase and amplitude errors of I/Q quadrature systems?
