Stumbled across this by chance while looking at the coal mines in the area.
Most of the electrical fittings are still present.
Theres also a large room which must have have housed the majority of the radio equipment, all that remains is one empty rack labelled 'BT Tan Hill to Bowes Radio Link'
A generator is still in place.
Also some parts of the fuel tank
All the dishes have been removed leaving a nice climbing frame in the middle of the building.
The search for coal mines was also successful.
