There are chasms in the ground - huge cracks in the limestone roughly three feet wide - that are so deep I couldn't see the bottom! The area surrounding the mast is quite popular with tourists and you are free to walk here, but you need to be very careful where you step, and not just because of the cliff edge. Stanton Moor and Bolehill were similarly moved to East Midlands, and this explains the unusual situation where their channels were interleaved with those of Waltham (now their parent station) in the original plan their channel allocations were based on Sutton Coldfield providing their feeds.
Update June 2013: Nigel Goodwin has been in touch and confirms that following the decision to change the editorial region for this relay (for what he describes as "political" reasons) it was found that only Stanton Moor provided the necessary incoming signal - reception from Waltham was impossible. It's likely that the Sutton Coldfield log is a legacy from the pre DSO analogue days, probably providing a West Midlands programme feed for the BBC channels. I doubt Waltham can be received directly, hence this arrangement. The mast is located some 700 ft asl, but is considerably lower than the surrounding hills.
The higher horizontally polarized RX yagi actually appears to be pointing to Sutton Coldfield - definitely not Waltham. There are two RX yagis, and, interestingly, Matlock appears to be a relay of a relay, judging from the vertically polarized one which points NW towards Stanton Moor, some five miles distant. It proved a bit of a challenge to photograph from the distance, and I hope you can even make out the mast in picture 2!
This is listed as a low power relay of Waltham, providing coverage in this very hilly and picturesque area. The tower is about sixty feet from the cliff edge, from where I took picture 7 looking down into the valley. High Tor is a 390ft high limestone cliff that rises sheer from the river Derwent's eastern bank, and is a popular climbing cliff. The Matlock UHF TX on cliff tops at High Tor in Matlock, Derbyshire. Matlock is a relay of Waltham (via Stanton Moor)
