I have recently received a LimeSDR and I am trying to use it connected to my Ubuntu 16.04 system. I have built LimeSuite and SoapySDR and installed gqrx successfully.

When I run lms7suite I can successfully connect to the LimeSDR, but when I try “Calibrate RX” I am getting an error “Rx calibration: Rx Calibration: bad SEL\_PATH”.

Any ideas on why this would be happening?

Hi John,  
Currently RX calibration does not work with LNAH. Switch the active path of the RXFE to either LNAL or LNAW.

Does RX calibration still not work with LNAH ?
