Projects

A home for the things I’m building around amateur radio — packet infrastructure, machine learning for signal identification, SDR experiments, and tools that make the underlying DSP visible.

Each project has its own page describing what it is, why I built it, where it’s at now, and links to related writing. Some are live services, others are ongoing experiments and works in progress.

Raspberry Pi SDR

A self-contained, off-the-shelf device that shows IQ data live on a touchscreen — and lets you listen to what you’re looking at.

GB7CAM Packet Node

A licensed packet radio node and supporting web infrastructure for the Cambridge area.

Radio Memory Builder

Generating organised memory-channel files for Yaesu FT5D and FTM-310 radios from the RSGB repeater list.

DSP Visualisations

Tools and writing that make IQ data and digital signal processing visible and intuitive.

AI Signal Classifier

Machine Learning

A machine-learning system that identifies amateur-radio modes from RF, with the goal of automatic decoding.

MMDVM Digital Voice Hotspot

A Raspberry Pi and MMDVM hat running WPSD, giving full-power-free access to the digital voice networks from home.
