Tacolneston and Mendlesham spring to mind.
Read somewhere that Tacolneston used HP to cut down on co-channel from/to Rowridge & Kirk-O-Shots, but there was a Dutch or Belgian TX already using that channel/frequency with HP & they had to have a very sharp null towards Holland/Belgium to placate them.... I was thinking of the early 50's when there were just the 5 (or 6, was Rowridge classed as high power?) main high power VP BBC TX's on air. I know as the late 50's progressed into the early 60's band one became stuffed to the rafters with BBC VP & HP TX's. If a frequency band could explode then the UK band one would have done...
