The site opened for programme service on 14th January 1958 though there was some public disappointment about the comparative grades of service in some shielded locations in the deeper valleys of South Wales and in low-lying parts of Bristol and Bath. This subsequently led to the use of well-designed receiving aerials and more sensitive 'fringe' area receivers have to some extent overcome the low signal strength and 'ghost' images experienced in such localities.
