I visited Pleumeur Baudou shortly after it opened, my father was an engineer with the French Telecom ministry (PTT at the time) and he knew people there. I remember the gigantic offset horn and the maser amplifier. Too bad I do not have pictures from this event.

I'd love to read the story. I visited Telstar ground station in Pleumeur-Bodou, France once. There is museum there now, called "Cite des Telecoms". They preserved original horn-like antenna used for Telstar communication and lots of original equipment. If I remember correctly there is even old hydrogen maser displayed. Place worth seeing.
