Bomere Heath ROC Post

A passing ex-BT engineer points out the location of this ROC post (YMGW passim). The posts were formed into clusters, and could communicate with each other, and with Group HQ, by means of a private circuit using a TeleTalk - shades of Orwell's 1984 telescreens. One post in each cluster was equipped with UHF radio, providing backup in the highly likely event of the telephone lines being taken out ... although presumably the aerial mast would have gone the same way. Bomere Heath was such a master post: there's an aerial connection point on the secondary ventilation shaft (above). Atop the primary ventilation shaft (below) is the circular mount for the ground zero indicator used to determine blast direction and elevation.
