Error with LimeSDR

[vchekan]

I am trying to run LimeSDR board and depending on settings, sometimes it works, sometimes it does not. In particular, I get this:

[WARNING] GetDC_IQ_Interp(108.05 MHz, ch=0, tx=0): no matches between [107.05, 109.05] MHz
[INFO] SoapyLMS7::setFrequency(Rx, 0, BB, 1.36124e-07 MHz)
