Isolated RF & DSP Conda Sandbox

Dev EnvironmentPre-configured

Overview & Purpose

Software Defined Radio toolchains rely on complex C++ and Python bindings that frequently conflict with standard OS package managers. TelcoChisel isolates GNU Radio 3.10, Gqrx, UHD, and vendor-neutral SoapySDR bindings inside a dedicated Conda sandbox environment named `telcosec-sdr`. This guarantees that Python pip installations or OS updates never break core RF transceivers or DSP flowgraphs.

Verification Command

Run the following to confirm this configuration is active on your system:

Isolated RF & DSP Conda Sandbox — Verification
conda activate telcosec-sdr && python3 -c 'import gnuradio; print(gnuradio.__version__)'

Configuration Details & Steps

TelcoChisel applies these settings automatically at ISO build time. The following steps document each configuration item:

  1. 1
    Activate the isolated SDR research sandbox: conda activate telcosec-sdr
  2. 2
    Verify GNU Radio version and core Python module import inside the sandbox: python3 -c 'import gnuradio; print(gnuradio.__version__)'
  3. 3
    Verify SoapySDR driver bindings inside the activated sandbox: SoapySDRUtil --info
  4. 4
    List installed SDR libraries and OOT signal processing modules: conda list -n telcosec-sdr

Troubleshooting

Common Issues
If `conda activate telcosec-sdr` returns 'conda: command not found', initialize the shell environment with `source /opt/conda/etc/profile.d/conda.sh` or ensure that the Conda initialization block in your shell profile has executed.

Frequently Asked Questions

Why use a Conda sandbox instead of native apt packages?

Native distribution repositories often ship outdated versions of GNU Radio or lack support for third-party Out-of-Tree (OOT) modules. A dedicated sandbox allows exact library pinning without risking system-level package corruption.

Can custom GNU Radio flowgraphs be run outside the sandbox?

Flowgraphs compiled into standalone Python scripts require the GNU Radio runtime, which resides inside the `telcosec-sdr` sandbox. Always activate the sandbox before executing SDR scripts.

Can I install additional Python libraries into the sandbox?

Yes. You can run `conda install` or `pip install` within the active `telcosec-sdr` environment to add specialized DSP algorithms, Scapy telecom extensions, or machine learning frameworks.
