What did that transmitter console comprise of?

Has anybody noticed the women, flowers in their perfect hairdos, dressed very nicely! What a downward change! 🥲

Thank you for demystifying this.

Hi noise levels has done more to reduce the number of hams, than any other issue, in my opinion. I have had several intersted young people get totally turned off of Amateur radio- particularly HF once they heard the s9 noise levels that come with it. It is HF that is truely magical as it is infrastructure independant. Why bother with digital UHF etc when its not much different from internet coms? Further long time hams like myself have left the hobbie due to total receiver noise blackouts. I even travled 300 miles north to a camping spot...it was just as bad as in the city due to trailers in nearby camping spots using SMPS! The ARRL and radio manufacturers are not doing enough to save their own servival. Finally, the governemnt has No desire to protect FREE Worldwide comms ! They want to control all information and censor those who may disagree with Globalism. The death of infrastructure independant coms for the public cannot come fast enough for them. Thats bandwidth that cn be be sold for encyrted, pay to use comms Of the future. Hopefully the saviour will be a realizrion that world wide ionispheric coms are cheap , infrastructure independand and required as a backup for Making America Great Again.

Back when Britain was British 😊

All great white men

I have a RCA wireless microphone that uses the Little tubes.

Ed - Your statement at time hack 35:16 is inaccurate regarding Collins Radio and SSB: "Collins Radio was not first nor very innovative, but had aggressive marketing". Some Collins innovations in SSB technology include (1) the Collins Mechanical Filter for high selectivity in transmitters and receivers; (2) the Permeability Tuned Oscillator for linear tuning, accuracy, and stability; and (3) RF feedback techniques for high linearity in RF Power Amplifiers. Almost all of the Collins engineers, managers, and marketing (including Arthur Collins) involved with HF SSB development were also active radio amateurs. The Collins 75A-4 and KWS-1, introduced in March 1955, incorporated these and other technical advancements.

I used to listen to HCJB in the early 1970s on a old Halicrafters SW radio in San Diego, California. They had this interval music that was a solo guitar with birds chirping in the background that would repeat and the a voice would say "HCJB, Voice of the Andes from Quito Ecuador." The tune is burned into my brain. I would love to obtain a recording of the music for no reason other than nostalgia.

I wander if silicosis was a problem with them?

the women were so delicate, elegant and refined back then.

Imagine just sorting and playing with large chunks of quartz all day. Would be an amazing job.

That person tracing out the non usable portions needs more training

11/15/24 I had the good fortune to own a working "Scott Special" in 2011-12 Richard Lee Pres. NJARC

What year was this filmed?

Fantastic talk. Thoroughly enjoyed it as a receiving ham here in UK. Thak you for posting.

Same women licking Radium.

As amazing as it is, this is still primitive compared to what the ancients, and some with secret knowledge can still do. We stand on the shoulders of giants.

See the Stromberg-Carlson SP-965-C "Integrity Series" stereo system showcased in the Twilight Zone Season 1 Episode 28 "A Nice Place to Visit".

Here we see a pair of skilled American enchantresses making war crystals.

Excellent love tubes have many radios and Dynaco gear RCA, Zenith, RadioShack shortwave tuner, Dynaco fm tube tuners

Who let the wizard have a camera!?imagine what they have locked away in their towers.

I absolutely appreciate these historic documentaries. straight simple and fancyless, information easy to understand.

This video reminds me of the safety standards at Victor Insulators, in victor NY..

I had a preview of this problem about 15 years ago in São Paulo Brazil. The city is a forest of 30-40 story apartment buildings, so the population is very dense and the noise floor is quite high. My friend put an AM radio in the window of his office building and tuned the dial. There was not ONE station that wasn’t covered with high levels of noise. One AM station was 5 km away and running 100 kw. Since then, most of the city’s AM stations have been voluntarily shut down. I realized then that it was a preview of what was coming to the US.

Great Story,Thanks for sharing,been a ham since the mid 70's..73's WA4WXX

One of the best film - SOE W/T History ! Super quality and knowledge !

Incredible we as humans found out this long and meticulous process, to have a final product to help transfer sounds, voices and music through air. What a work it was. Or perhaps still is... Not sure how they make crystals today.

Love your CW Muzak to my old shell like ears. ☮️ 🤙 fm the land of the Vk6 & 🦘

9:17 the safety standards

I think it is possible to create a computer with no crystal oscillator for the computer chip. It's source code (frequency) is instead based on the magnetism of protons, electrons, and neutrons, using triangular, 3 charge (+,-,=) circuits. Which is not as much of a wave, but more of a geometric pattern, but made of waves.

Clearly and simply explained. It would also be good to explain why a Pi network network reduces harmonics.

the level of detail, craft(wo)manship, and labor made me realize my work pales in comparison, but their work is an inspiration

I really enjoyed this video. What a great show of what people can do if they really work together.

Fascinating video thanks👍

When Windows 95 came out a computer scientist was being interviewed about it on Morning Edition. He said that modern (1995) desktops are often compared to room filling vacuum tube computers of the 1950s. But, he said, there's really no comparison. If one were to build the Pentium processor needed to run Windows 95, just that one chip, out of subminiature vacuum tubes they would fill the Pentagon.

These crystals were made for equipment made keeping countless young people risking their lives overseas hoping to come home safely. Nobody could imagine at the time how or when WW2 would end.

Good Lord, the amount of processing.

I think if you had an HT4 in 1939 you be a Big Gun, 400 watts AM plate modulation. I could only dream of such a radio transmitter when I was young looking at 1945 ARRL manual. A superb heavy duty transmitter, amazing work feat of design and production. Regards Tony ham radio ve4akf

WHAAAAAT?! This is incredible! Rhetorical question: 1.) How did this even get discovered? 2.) How long did it take to figure out each step, and 3.) 1.) how long did it take to mechanize each step so it's a large-scale factory production?!

Very informative and helpful! Thank you for sharing this very useful and eye-opening information! 🗼📡📶📻

My grandfather built a crystal radio in his family's barn. His parents thought radio was the devil, which is wacky, everyone knows geology is the devil.

This is fascinating on so many different levels! 🤓

The fact that a plastic holder was used when immersing the crystals in the etching solution, highlights that "solution" is hydrofluoric acid. Even a little bit gets on you, and you're likely to have very negative effects down the road, if not within hours, because it soaks all the way to the bone. A tiny drop on one's skin, might not even be felt, which makes it even more dangerous, as every second it isn't wiped, washed, or rinsed off, means more penetrates into one's body. The dangers of working with hydrofluoric acid were already well known by 1943, when this film was produced, so I wonder, if they left off their gloves or other personal protection just for the film's aesthetics? I saw a lot of the women workers in their Sunday best w/ fingers full of jewelry, ready to be caught in machinery, touch electrical contacts, or trap chemicals between their jewelry & their skin. Were some even told to doll themselves or their hands up just for the film, or was such blatant disregard for safety just another day on the job?

I want to see the gas powered radio...🙃

Thank goodness someone invented the transistor.

AS a Scott owner, I knew some of this, but you added a lot.Great presentation

The Education of Little Tree...😯
