Hi Magnus its was a pity they didn't manage to communicate with some of my
office collegues so as to to confirm the "hand" of the polarisation they
were using though :-)) Goodhilly changed the feed for the other polarisation
on the day of the first test, and it was a bit of a TV disaster. Lanion had
a horn so had the same sytem. The horns are long gone except for the
microwave background experiment but the Goonhilly Down dish called "Arthur"
after a certain medieval king who spent his time whopping Danes :-)) I dont
think the dish still carries traffic but it is capable, fully steerables are
not needed for telecoms now. Arthur is now a "historic monument" so we do
get some things right !!
