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

BladeRF

  • gain_mode :
    • 0 is device default
    • 1 is manual
    • 2 is fast AGC
    • 3 is slow AGC
    • 4 is hybrid AGC
  • gain : General Gain in dBs
  • bias : Bias-Tee power (BladeRF 2.0 only)

LimeSDR

  • gain : 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
  • am_notch : Enable the AM notch filter
  • 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 is 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

PlutoSDR

  • gain : Device Gain in dBs
  • gain_mode : Gain mode :
    • 1 is Manual
    • 2 is Fast Attack
    • 3 is Slow Attack
    • 4 is Hybrid

USRP

  • gain : Device Gain in dBs
  • channel : Channel ID
  • antenna : Antenna ID
  • bit_depth : Bit depth. Can be 16 on all devices, 8 or 12 on some

MiriSDR

  • gain : Device Gain in dBs
  • bias : Enable Bias-Tree power
