You seem totally confused about the difference between an Air Ground operator and an Air Traffic Controller. Mind you, whatever their merits otherwise, the operators of Popham add to that confusion on their website by their reference to the Air Ground Communication Service as "ATC" ("because that's how other people refer to it"), in quote marks initially but then eventually even dispensing with them in a further reference. To my mind, they should be told by CAA to get their house in order and refer to the service correctly - as should a certain other aerodrome not a million miles away that advertises "Air Traffic Control" on the tower building - again, only an AGCS.
