Always-On SDR: Building a Multi-Band Radio Intelligence Platform on Kubernetes I have been quietly building something i am pretty excited about. The idea started simple enough: i wanted a permanent, always-on radio monitor for 2m. It grew into something considerably larger. Today the stack covers 2m, 70cm, and the full HF spectrum from 3–28 MHz simultaneously: recording, decoding, transcribing, and tagging everything it hears, around the clock, with no manual intervention. ...

Introducing Sola Coffea After approximately three years of development, I am pleased to announce that Sola Coffea is now available on the App Store. It is a native iOS application constructed for individuals who approach their coffee with deliberation, whether you are cataloguing single-origin beans, calibrating espresso extractions, or discovering new establishments while traveling. What originated as a simple coffee logging concept evolved into a comprehensive platform encompassing brew analytics, social features (coming in V2), shop discovery, and a dedicated business tier for roasters and cafe proprietors. ...

Navigating to a Grafana instance via a mobile browser is an exercise in frustration. You encounter compact text, unresponsive panels, and an interface that was never designed for smaller displays. So I decided to create something better. ...

Setting Up an ADS‑B Flight Tracker with a Cheap Antenna on Kubernetes (RKE2 and ArgoCD) This is the Kubernetes version of my earlier Docker‑based ADS‑B guide. In this setup, everything is defined in YAML and deployed via ArgoCD, and changes are tracked in Git and synced automatically to the cluster. Access is handled through an NGINX Ingress with TLS from cert‑manager, which is how I publish the ADS‑B UI at adsb.w3rdw.radio. If you’re comfortable editing YAML and committing to Git, you’ll feel right at home. ...
