FM Receiver with GNU Radio- Week 2

FM Receiver App – Week 2 Update

This week, I made progress in the following features:

Establishing a comprehensive project directory structure
Designing and prototyping the user interface (UI)

1. Repository Structure Setup

I used python project templates along with AI to helping shape the structure in a clean, scalable format.

Here’s the high-level breakdown:

fm-receiver-app/
├── docs/              # Documentation (Installation, Dev Guide, etc.)
├── flowgraphs/        # GNU Radio Companion (.grc) + generated Python
├── src/               # Main application (core logic, GUI, utils)
├── tests/             # Unit and integration tests
├── scripts/           # Dev utilities (build, package, test)
├── examples/          # Sample setups for different SDRs
├── packaging/         # OS-specific distribution configs
├── data/              # Sample recordings and configs
├── README.md, setup.py, requirements.txt, etc.

Some key highlights:

flowgraphs/ contains .grc and autogenerated Python scripts for different receiver modes (basic FM, RDS, etc.).
src/fm_receiver/gui/ holds all the GUI components, organized by responsibility (e.g., spectrum, control panel, RDS).
core/ contains the interface to GNU Radio, signal processing, and audio handling.
utils/ supports tasks like frequency conversions, logging, and file I/O.
Tests are separated into functional and integration layers to keep development reliable and regression-free.

This structure sets the foundation for long-term maintainability and team collaboration.

2. UI Design Progress

After drafting the initial layout with pencil sketches, I moved into high-fidelity Figma mockups and started implementing the first working UI in PyQt5.
