Confirming our QSO
Amateur radio, mostly from Norwegian mountains and parks. I write about my SOTA and POTA trips, the antennas I try out, and the software I build for the hobby.
Too much ham radio software is closed source, so I wrote VardeFM: an open-source FM data modem that works with Winlink Express, Pat and other VARA apps as a drop-in replacement. It has made its first trips over the air, and I'm looking for people to help test it.
For almost two years I've been building VoiceQSO, an Android app that turns a recording of your contact into a finished log entry. It went into production this summer, and it syncs with QRZ.com, Wavelog, ADIF and Cabrillo.
My latest project is Kallesignal.no, an online course in Norwegian, built from my LA2T course slides, that takes you all the way to the amateur radio licence exam. It has 129 short lessons, animations you control yourself, and mock exams built like the real one.
How we decoded the Modbus-over-BLE protocol used by the HC BMS Android app, including the GATT layout, the six polling requests, frame formats, and the OTA bootloader trap that almost bricked our session.
While being under the weather, I spent some time doing POTA and SOTA hunting. The existing tools are pretty good, but I always felt it would be great to see activations on a map, not just a list. So, I created an app for that: SpotMap.
