Field Dossier // Operator
Welcome to HB9HCR
Chris here — a Swiss OP, vintage 1980, active on HF, UHF and VHF.
Three months of self-study, zero electronics background, and one exam later: HB9 licensed in 2019. Still proud of that one.
Then the silence hit. No contacts, no experience, no patience — and just like that, the fire went out.
At the start of 2026 I joined HB9UF and USKA, and lit it back up. My shack? Anywhere under the sky, running up to 100 whiskey.
So every QSO you log with me came from outdoors, with real effort behind it.

Bunkers On The Air
Activating bunkers for WWBOTA has become my favorite radio activity.
I enjoy the cooperative soul the programme has and I have set my personal campaign to personally activate as many objects as possible in the Limmatstellung.
Doing so, I am happy about every single award I get.
A few years serving the Swiss Armed Forces as a sargeant connected me with these historical sites — some of them became a home for a while.

§ Historic Background
Within a 10 km radius of where I live sit about 300 relevant objects — the region falls inside a natural choke point valley called Limmattal.
Known as Sperrstelle Urdorf, it was the key installation in a larger, in WWII nationally significant defensive line called Limmatstellung.
Built to stop enemy ground advances toward the Reusstal and the Gotthard Massif, the direction the Swiss would have retreated to under invasion.
Across the valley lays a 3 km wide tank obstacle cutting straight through our backyards, flanked by numerous machine gun nests, cannon emplacements, and infantry and nuclear shelters.

The Limmatstellung doesn't give up its concrete easily. Every clasp below is an operation. A handful of bunkers activated together, set by set, log to log. 22 operations consisting of 272 bunkers grouped in 58 sets. And the valley still has more silent positions waiting to be remembered in frequency.

§ Long Distance
The Maximum Usable Frequency map shows the highest frequency likely to skip off the ionosphere and reach distant stations right now — the higher the MUF over a path, the better your odds on 20m and up.
§ Short Distance
The FoF2 map tracks the critical frequency of the F2 layer straight overhead — a rough ceiling for what will reflect back to earth nearby rather than punch through to space, useful for regional contacts.
