A Ham Radio Field Station

Signals from the Rhine & Beyond

Trail notes, QSOs and handlebar hours from Koblenz. Summits · parks · portable antennas · loaded panniers · a soldering iron still warm on the bench.

Station Keeper

file no. 001

Part engineer, part radio amateur. One foot in the compiler, the other in a well-worn cycling shoe halfway up a Hunsrück summit.

I'm Patrik, callsign DO9PSE, broadcasting from Koblenz at the confluence of the Rhine and Moselle. Licensed since 2004 and still tinkering. By day I write software; by evening I'm chasing propagation on twenty metres or winding a common-mode choke at the kitchen table.

Most trips I reach under my own power. A loaded bikepacking rig carries the radio, the wire and the coffee; the legs carry the rest. This station runs on curiosity and 5 watts of QRP.
