OK, when I add:

"RF=14,BB=16,IF=8"


I still see this from gnss-sdr:

Using HackRF One with firmware 2017.02.1
Enabled antenna bias voltage
Actual RX Rate: 8000000.000000 [SPS]...
Actual RX Freq: 1575420000.000000 [Hz]...
PLL Frequency tune error 0.000000 [Hz]...

Actual RX Gain: 14.000000 dB...

gr::buffer::allocate_buffer: warning: tried to allocate

Where the Actual gain is 14dB.  Nothing I do changes that value....

How do I know what the total value is (or if even these amplifier settings are even being written)?

Thanks,

Herb
