Relayed by Chris Suslowicz:
At OSE8 (Skelton A) one dark, damp night, a TA (Technical Assistant, aka erk) was using the station bicycle (no, not that one) to trundle out to a remote array switch when the Overseas Service (aka World Service) aerial feeder decided to arc during a radio play. The erk returned eventually to the control room looking white and shaken and reporting that he'd been half way to the switch when a ghostly voice had boomed out "THIS IS THE VOICE OF GOD...".
During the war, all the arrays were guarded by the Home Guard, etc., who reported the same sort of thing but also new recruits would occasionally return to the guard post twitching and claiming they were under attack. It just so happens that in the dark, a sheep coughing sounds completely human.
 Overseas Extension No 8, half of the huge Skelton site near Penrith in Cumberland (then). It ran pairs of 50Kw Marconi SWB18 Txs into Sterba curtains via 600 ohm (?) open wire feeders with one set of arrays slewable and reversible (think HF stacked yagis) via an enormous patching panel operated with a _long_ pole.
Chris. (Apparently _all_ the control room telephones for the transmitter sites had standard bakelite telephones. Standard except for the rotary dial, the exposed parts of which were made of wood to prevent you getting RF burns from exposed metalwork....)
