SDR Options

This aims at covering all available SDR Settings for supported devices / sources. The goal is not to explain what every option does (for that, see the manufacturer's documentation for the specific device), but rather allow users to find the right flags in CLI mode.

Where possible, consistency was kept to be rather easy to "guess" if you know what you are looking for.

Airspy

gain_type : The gain mode used by the device :
- 0 is for Sensitive
- 1 is for Linear
- 2 is for Manual
general_gain : Overall gain for sensitive and linear mode. Ranges from 0 to 21, in dBs
lna_gain, mixer_gain, vga_gain : Used for manual gain tuning only
bias : Enable Bias-Tee power
lna_agc : Enable the LNA AGC
mixer_agc : Enable the Mixer AGC

AirspyHF

agc_mode : 0 for disabled, otherwise :
- 1 for LOW
- 2 for HIGH
attenuation : Attenuation in dBs
hf_lna : Enable or disable the HF LNA

HackRF

amp : Enable the main (non-programmable) amplifier
lna_gain : LNA Gain in dBs
vga_gain : VGA Gain in dBs
bias : Enable Bias-Tree power

LimeSDR

tia_gain : TIA Gain in dBs
lna_gain : LNA Gain in dBs
pga_gain : PGA Gain in dBs

RTL-SDR

gain : Device Gain in dBs
agc : Enable or disable the AGC
bias : Enable Bias-Tree power

SDDC (RX888, RX999, etc)

Note : Support for those is experimental. Things may not work as expected!

mode : 0 for HF, 1 for VHF
rf_gain : RF Gain in dBs
if_gain : IF Gain in dBs
bias : Enable Bias-Tree power

SDRPlay

Note : some options are device-specific!

lna_gain : LNA Gain in dBs
if_gain : IF Gain in dBs
bias : Enable Bias-Tree power
fm_notch : Enable the FM notch filter
dab_notch : Enable the DAB notch filter
am_port : Select the AM antenna port
antenna_input : Select a specific antenna input. 0 is the first input
agc_mode : AGC Mode, 0 is disabled :
- 1 if 5Hz
- 2 is 50Hz
- 3 is 500Hz

SpyServer

ip_address : IPv4 Server address
port : Server port. Usually 5555
bit_depth : Bit depth to stream at. Options are 8/16/32
gain : Device gain in dBs
digital_gain : Software gain, in dBs
