One of three remotely controlled nuclear monitoring posts is located in a large German bunker at Gouray. Access to the bunker is down a flight of stairs to one side of the aerial compound.
Prior to 1991, this post would have been manned during exercises and would have performed the same function as a mainland Royal Observer Corps post, sending data back to CD Headquarters in St. Helier. The only evidence on the surface are the aerials, sensors and detectors for the monitoring instrument. There is also an FSM pipe nearby similar to those found at mainland Royal Observer Corps Posts. During an exercise the flat plate on top of the pipe would have been unbolted and replaced with a plastic dome. The external probe of a Plessey PDRM82F would then be pushed into this dome from inside the bunker using a long metal rod that can be fixed in place to the bottom of the pipe. This is no longer used as the post is now remotely controlled.
Only part of the bunker has been utilised with a central corridor giving access to a number of rooms. The Mini Instruments 7-50 recording device for measuring temperature, wind speed, wind direction and radiation levels sits on a shelf in the corner of one room with a desk and telephone below it. At the end of the corridor wooden steps lead up to the bottom of the FSM pipe. Any furniture has now been removed and the only other equipment belongs to Jersey Telecomm and a cable company who also share the bunker.
Those taking part in the visit were Nick Catford, Keith Ward, and Robin Cherry.
