If you look into sdrTest – main you can see the current list –

A quick summary of the options-

-debug – turn on debug print out
-am – set mode to am
-fm – set mode of fm
-nbfm – set mode to narrow band fm
-usb – set mode to upper sideband
-lsd – set mode to lower sideband
-gain 1.0 – set audio gain to maximum gain
-fc 1e6 – set center frequency to 1 MHZ
-f 0.76e6 – set receive frequency to 760,000 HZ abs(f-fc) needs to less that 0.5*samplerate;

-device 0 – select SDR device 0

-audiodevice 1 – select audio output device 1

-timeout 10 – play for 10 seconds then quit the program.

-samplerate 10e6 – set sample rate to 10 MHZ

-faudio 48000 – this is the default audio rate and you normally do not change it, expect when you are writing to a file

-antenna “Tuner 1 50 ohm”

In you case
Rx antennas:
Tuner 1 50 ohm
Tuner 1 Hi-Z
Tuner 2 50 ohm

-set rfnotch_ctrl true – turn on the notch filter (i.e. kill AM and FM bands)
-set dabnotch_ctrl true – turn on the dabnotch filter (i.e. kill dab bands)
-set biasT_ctrl true – turn on voltage to power external antenna device

in you case the set options are, but I not sure what the rest of them are for –

Setting Info:
key rfgain_sel value 4 read 4 type 3 min 0 max 0 step 1.17877e-310
key iqcorr_ctrl value true read true type 0 min 0 max 0 step 1.09123e+265
key agc_setpoint value -30 read -30 type 1 min -60 max 0 step 0
key extref_ctrl value true read false type 0 min 0 max 0 step 1.15312e-271
key biasT_ctrl value true read false type 0 min 0 max 0 step 4.97896e-313
key rfnotch_ctrl value true read false type 0 min 0 max 0 step 1.09123e+265
key dabnotch_ctrl value true read false type 0 min 0 max 0 step 1.17877e-310

-dumpbyminute – dumps I/Q files every minute
-file fileout – writes the audio output to file out
-PPM -0.380 – does not seem work

What is missing is the control for the gains –

In you case –

Gain range RX min 0 max 48

Gains:
0 IFGR range max 59 min 20
1 RFGR range max 9 min 0

It only another 20 lines of code, but I have not gotten around to it yet since the defaults usually work OK.
