Used antenna - Arecio antenna collapses

If you want a good buy on a used, high gain antenna, the Arecibo radio astronomy antenna will soon be up for grabs. Sold as is, where is. Some assembly required.

Pick up only. Bring a big truck.

Re: Used antenna - Arecio antenna collapses

Sorry, not funny.

Arecibo was a great site and there are a number of Hams that are part of
the dish and who were employed thanks to the installation.

It is a pretty sad day, not only for the loss of technology, but also their
livelihood.

Re: Used antenna - Arecio antenna collapses

Tragic. Anyone who has visited it in the past will be saddened to see
its condition now.

I was there in the 80's. I went on a lark, traveling by "publico" from
San Juan where my ship was docked for a few hours. I had trouble even
finding the place until I found out it was referred to by locals as
"Esperanza radar". The trip and the view were memorable; seeing that
gleaming-white symbol of advanced technology filling the valley was so
impressive!

I used to tell people traveling to Puerto Rico to make sure and see
Arecibo. Now I guess I can tell them to go see the ruins.

Re: Used antenna - Arecio antenna collapses

There are some interesting tidbits about Arecibo:

Joe Taylor, K1JT, or wsjt-x fame, did some of the work that lead
to his Nobel Prize at Arecibo. His also mounted an 'expedition'
in April 2010 to use the Arecibo Radio Telescope to conduct
moonbounce with Amateurs around the world using voice, Morse
code, and digital communications. [Wikipedia]

The Arecibo radio telescope was used as a powerful radar to
study other objects in the solar system. Things at certain
distances could not be studied because by the time the
transmitted signal reflected back, the Earth had turned enough
that the radio telescope was pointed in the wrong direction.

It's definitely a sad occurence. I sympathize with the people
who use black humor to handle their sadness.

Really a shame to see its demise. It might not be re-built in Puerto
Rico due to exposure to Hurricanes and encroaching civilization
threatens the radio quiet area for useful radio astronomy. Wonder if
a new site might be chosen (someday)?

I copied the 432 MHz SSB signal from Arecibo using my 16-foot dish
and a hastily made 432 feed. I tried sending JT65 signals at 100w
but never got a reply.

In my college years radio astronomy was one of my career choices and
I even got an invite to do Master's study at Ohio State with Dr. John
Kraus-W8JK (who built the "Big Ear" radiotelescope). But was not to
be - I moved to LA in Nov. 1968 to start work with Hughes Aircraft on
military projects. (don't ask)

Later in 1972, I did some minor radio astronomy using a 26m dish at Goldstone.

A lot of neat science was done at Arecibo. Always wanted to visit
(too late now). I did get to see the Big Ear about 3-months before
is was torn down to build a golf course.

This where I could make a political joke (but won't).
