About me

I'm Allan, a Danish radio amateur — formerly OZ1DSK, now OZ7Z — with a soft spot for the bands from 144 MHz and up. Most of my time on the air goes to VHF/SHF contests — on my own call, often portable, and as one of the operators at the contest station OZ1ALS — and to 10 GHz EME, where the signal goes to the Moon and back.

I'm also the webmaster of vushf.dk and contest manager, so I look after the Danish VHF/UHF/SHF contests and the site where the logs are sent in and the results are published.

When I can't find the tool I want, I build it myself: a contest logger that runs in the browser, a Moon-tracking rotor controller written in Rust, and small ESP32 gadgets for the shack. Everything runs on Linux.

VHF Logger

VHF Logger in Simple mode: log list and a map of worked locator squares

A contest logger in the browser

Log VHF, UHF and SHF contest QSOs, see the score and the map, and export EDI for vushf.dk — no installation. When you want more: ON4KST chat, aircraft scatter prediction and sync with Tucnak and WSJT-X.
