I see Auntie Beeb retired from that site a few years ago but the sign out front refers to Merlin Communications. I see Merlin is considered a Telcom, so how much of Rampisham is actually putting out RF?
Not much now, most of the towers have gone and the only one that are left either have satellite links, mobile phone equipment (although that is limited to a short stayed mast in front of the main building) and a low power TV relay.
In it's heyday it had BBC world service, Russia Today, Deutsche Welle amongst other broadcast using 34 wideband curtain arrays and 10 500kW transmitters.
It was quite a sight when you passed it (it was on a secondary "A" road between Crewkerne and Maiden Newton) but looks a bit forlorn now.
It's location is supposedly on a main electricity line and was originally built for war use, with civilian use coming later on.
As for being owned by Merlin/Babcock, despite merlin being a telecommunications company they ended up owning all? of our SW sites.
