Re: Gain range - again!
Finally worked it out - I need to use the LNAstate parameter of mir_sdr_RSP_SetGr() to switch the LNA and mixer gains. The API Specification document would be less confusing if the Gain Reduction Tables were not in a completely separate section (or even document!) from the functions they relate to, ...

Please can someone tell me why the minimum value for IFGR allowed by SoapySDRPlay is 20 rather than 0?
Thank you,
