Re: [Elecraft] Used antenna - Arecio antenna collapses
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). 73, Ed - KL7UW Date: Wed, 2 Dec 2020 14:51:02 -0500 From: Bill Frantz To: elecraft@mailman.qth.net Subject: Re: [Elecraft] 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.

Re: [Elecraft] 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. 73, Drew AF2Z On 12/02/20 10:12, Michael Walker wrote: Sorry, not funny.
