[time-nuts] 60 KHz Receiver

[shalimr9 at gmail.com]

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.

Could you tell me which book you have on mind ? 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.

BR,
