[Hackrf-dev] HackRF Amp, RF and LNA gain setting?

[Sims, William Herb (MSFC-ES63)]

Guys and Gals,

I am trying to pass arguments to the HackRF One unit via the gnss-sdr program.

I have determined that to turn the bias on/off the argument label is

bias=1

What are the argument labels to turn the amplifier, LNA and IF amplifiers on?

Thanks in advance,

Herb

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
