Station description

It was initially at the home of the operator Sidney Dennis at Park Wood Farm, Upper Dicker. It was located inside a cupboard in a locked room in the house.

During the war, in 1943, Sidney Dinnis moved to a tenanted farm a few miles away closer to the coast, Priory Farm, Wilmington near Polegate, East Sussex. This land included the Long Man of Wilmington or the Wilmington Giant. This was of course turfed over. He had a wireless aerial up the chimney. The Farmhouse was demolished and replaced in 2013.

Mr Percy Ade, thought to be involved at Cowbeech Outstation, lived in the next door Wilmington Priory in 1939 and through to his death in 1948. He may have been an Operator or an Observer.

As children in the 1950s his grandchildren knew the subsequent owners of the Park Wood Farm and played in the wood behind the farmhouse. A bunker was situated at the higher end of the wood surrounded by a wide spread of low growing brambles. Documentary evidence from a war diary at The National Archives has proven it to have been built by the army as an experimental bunker whilst based in the area for a period of time and not SD related.
