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.

DSP Visualisations

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

GB7CAM Packet Node

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

AI Signal Classifier

Machine Learning

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

Radio Memory Builder

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

MMDVM Digital Voice Hotspot

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

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.
