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).

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.
