SDRCAP

A software defined radio recording library in python.

Organized as a Python Pip Poetry project. Currently only limited support for RTL-SDR via pyrtlsdr package with others to be added.

Setup

Installing

1. Obtain pyproject.toml & poetry.lock
2. in root of project, run

poetry install

Both toml and lock files are currently version controlled

Running

Try out the example!

poetry run python examples/example_usage.py

In general, the library is organized around you calling the library -> hardware device interface -> functions We define the hardware device interface in the python file and class name:

For RTLSDRv4 devices:

from sdrcap import rtl_interface 

Output

Currently the recording output supports CSV and HDF5 filetypes.

Dependencies

setuptool is needed for MACOS to import packages

A environment setting script is set to bind the poetry environments rtlsdrlib but shouldn't be necessary if you are explicitly doing:

poetry run python ${target}

instead of:

poetry shell
python ${target}

due to differences in potential python environments. If you want to use it run:

source set_env.sh

then run:

sudo -E python ${target}

where -E attached to sudo retains the environment variable you sourced from the shell script.

TODO's

For RTLSDR: 0. Support multiple devices

1. Support all rtlsdr.rtlsdr.BaseRtlSdr API options
2. Support asyncio streaming
3. Support/ expand TCP server client functions -> rtlsdr.rtlsdrtcp
4. Add compliant encryption for data at rest, data in air
5. Add on more advanced data transformation, interpolation, sniffing and analysis features

In general: 0. Solid support for receive only functionality cross SDR's

1. GNU Radio integration/ experimentation
2. GUI client app?

SDR devices to add (not in order): 0.
