The Rise and Fall of the World's Largest Radio Telescope
You need to think big to find answers to the fundamental questions of the universe. How about building a 1000 foot diameter radio telescope into a natural sinkhole, with cryogenically cooled receivers suspended 492 feet above by bridge cables. That was the Aricebo Radio Telescope.
Completed in 1963, it was the world's largest single-aperture telescope for 53 years, only surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China. Following two breaks in cables supporting the receiver platform in mid-2020, the National Science Foundation decommissioned the telescope. A full collapse of the telescope occurred on December 1, 2020, before either repairs or co...

Fraudsters and Charlatans: The Problem of 'Fake News' on the Radio, 1920-1930.
Просмотров 1,7 тыс.4 месяца назад
When commercial radio came onto the scene in 1920, listeners were amazed. This new mass medium brought music, sports, religious services, and so much more into their homes for free. But amidst the singers, and the sports reports, and the religious sermons, there were also some fraudsters and charlatans. Early radio was an all-volunteer enterprise, and on many local stations, informational talks...
The Amazing History of Microelectronics

How we think about invention tells us a good deal about who we are and what we value as a society. The longstanding ideal of American inventiveness-the belief that Americans are a uniquely enterprising and creative people-contains assumptions that historically functioned to exclude and discount the contributions of marginalized peoples. In this presentation Antique Wireless Museum Historian Rod...

These old-school instructional videos are top-notch in disseminating information. Concise. Masculine no-nonsense tone. 🤌
Seems pointless, just buy new capacitors!
The attention to detail your crews put in is second to none, truly awesome work.
1940's solid state microelectronics Love it!
👍👌👏 Oh WOW, simply fantastic! What an effort this was. Thanks a lot for uploading and sharing. Best regards luck and especially health to all involved people.
Wonderful historical account.
I am really surprised they have an ALDA transceiver and Dentron Transceiver. Didn't know they actually produced the Dentron.
The Model 28's sound was apparently what was recorded in the teletype room of WCBS Newsradio 88 in New York as heard behind their anchors from around late 1972 to c.1987. The sound differs significantly from the 15's; also, they had three 28 KSR's in a corner of their teletype room, and based on the sound coming therefrom it was there where that audio was recorded. In a sense, its "light touch" sound, conveying a sense of elegance and class, fit in with parent CBS's designation as the "Tiffany Network."
This why crowns contain so much crystal😮 They comunicated with their crowns😊
Great subjects! Unfortunately, the echoey audio prevents me from watching this video. Suggest you fix and re-post. I visited the antenna a couple years before the collapse
Interesting story, life is not perfect lower your bar your missing out.
So where were the SETI at Home receivers, digitizes and digital data recorders located? I ran the SETI&Home screensaves on many my PC's from August 1999 up untill they ended the program.

Ohh I am having a moment !!!!!!
I heard an Arecibo broadcast on 430 MHz many years ago!! Good Vídeo!! TNX 73!!
this looks really interesting but i just cant
Excellent Presentation! Thank you.
Dr. Craft, During your incredibly interesting presentation I kept waiting for an amateur radio connection. I'm sure that Angel V. and other staff and visitors must have utilized amateur radio as a hobby and a link to the states. I hope the new visitor center also has a variety of repeaters that could be very useful in times of disasters Thus fulfilling one of the amateur radio fundamentals to serve the public good. 73
That echo is really distracting. 😥 I wish the audio was clear.
maybe he can reupload the video without that echo, normal audio.

Loved to listen to them in the 70s. Big signal in Chicago.
Sir AA8 you are very good you can teach me all the Amteur radio technic
Sir I am seriously enjoying your presentation
Question: what is the formulae in placing our Antenna up off ground at specific frequency
Question : what governs the antenna thickness in relation to the 50 watts RF output Transceiver
Sir I do like your presentation
This was great Im glad i happened upon it.. America really was no 1 , what a mess they've made of the west now.
Great talk using fascinating research. Well done!
That's a flouroscope XRD.
A really interesting presentation. I used an HRO as a teenager in the 1970s and it was fascinating to find out more about these great radios. Thank you so much!
I got an old Philco radio from my grandpa and I know nothing about creating circuit boards. Is there a place I can buy a pre-built battery eliminator?
Great presentation. A worthy endeavor!
It's wonderful to step back in time and see the greatest generation getting down to the business of saving the world from tyranny. Each of them were contributing their small part to ensure victory. I'm sure many of the women in the film were quietly praying for their husbands, fathers or brothers while working hard every day. It reminds me of the famous poster of the woman rolling up her sleeve with the title, "We can do this!" and another one that says, "Do the job he left behind". Thanks to all of you who made the world safer for future generations. I hope we can do the same if it's ever needed.
Very well done and interesting video. I have a different theory, as a pilot’s daughter but I learned a lot! Thanks for making this available for all of us who continue to have Amelia living in our hearts 👍🏻🙏
$5,000 a year salary before the war must have been really spectacular to translate radio transmissions.
Amazing the skill required by the mostly women tuning these crystals. Amazing the precision achieved with such old machinery. Interesting to see how people interacting so directly with physical science. ie. squeeze the crystal and measure the voltage. These are artists.
"out standing in my field" ABSOLUTELY AWESOME. 630 seems very cool
Thank you for this, I was thinking the other day how much id like to see historical education. Instant Subscribe
Absolutely fascinating:]
To get to optimal acceptance is crazy 🤪
Started in the late 50's playing with an old Zenith console shortwave radio, my Elmer in 1962 was my Jr High shop teacher, W0DPB....gave me the novice exam which I finally passed, was WN0EQV...first workable station was an Eico cw transmitter with a 6146 final, Hallicrafters SX140 receiver and a folded dipole made from 300 ohm twinlead.........played with a Knight kit tube type CB after that..........1974........same elmer gave me the novice exam again, WN0NBA...............later that year, FCC exam in St Paul, MN........passed General exam with the code at 13wpm............still a ham WB0NBA....50 yrs same call.....some years of little activity, but still at it! , built and operated lots of Heathkit stuff in the 70"s.........didn't have much money then. still have a couple boatanchors ( Swan 500C and Kenwood TS520) that I operate along with modern Yaesu stuff.......not much effort to get licensed nowdays, get online, couple weeks memorizing test questions, get out your checkbook or C Card, buy latest gear, now your'e an Extra class in a few months........very apparent when on the bands nowdays..
She was using a fluoroscope to find that axes...ohh boy this is the crystal version of the Radium girls.
Well that make the movie “The Dark Crystal” just a little bit darker.
Not the exposure to x-rays
I wonder if the workers dressed up for the filming ?
What if used nitrogen gas to cooling vacuum tubes?
I cannot believe that all of these processes and methods were thought of by other humans. The amount of engineering and testing to make these precise machines is insane.
Helped jig tune and ship 100's crystal filters almost all passed QC,crystals were lapped on site an amazing substance!!!
CRYSTAL ARE NOW GROWN BY A COMPANY IN OHIO AND JAPAN !!!!
Great video!
