NASA's Apollo TV Lies Revealed - PART 3 - The crop

[az09]

Hi all i am new here and this is my first post/thread starter.Hope you are all keeping well.First may i sate that i am NOT a believer in the Moon Hoax theory.I am posting the below in an attempt to gain better understanding of the subject matter contained in this video.

quote from source from u-tube video;

"Back in Part 2, I conclusively demonstrated that NASA has indeed LIED to the world about the true purposes of the quindar tones you hear in the GCTA footage, and in Part 3 you will see examples showing the various editing techniques they exploited in order to erase or cover up the majority of the quindar tones that were actually being created by the digital editing system".



While i am no expert in "quindar tonnes" i am still trying to see where this video is going.Can anyone please shed some light on this , i would be most grateful, cheers in advance.





Found this video, its part 3 ,CANNOT FIND PART 1 AND 2.Looking for them.

This has been mentioned before I think? The search just fell over on me. Google throws up some with this board. Here is one.

Think the video is about a certain person trying to prove it was a hoax and the astronauts were cued by the tones. From memory.

The rest are quite easily founf on yuotube by Lunacognita I think. Pop that in the search.

And did we have digital video editing in the late 60's?

I watched the first 5 minutes of the video and couldn't really tell how it related to what the was trying to show.

He leaves out any connection between how showing a few stretches of video with only the astronauts talking proves anything about the quindar tones. Same thing with the "backroom chatter." Why does playing the video at half speed make any difference? He makes simple assertions with no logical connection. So much for proof.

He also fails to identify the source of his video, a crucial error. The "backroom chatter" was recorded separately from the video and astronaut audio. The backroom conversations had nothing to do with the quindar tones which were only linked to the capcom. Any pairings of audio and video were made during the production of his video. Not by NASA.

I've known about this one for quite some time. Quindar tones have a very well documented purpose: they mute and unmute uplink audio.

Apollo uses a "full duplex" communication system. The ground transmits to the spacecraft on one frequency, and the spacecraft transmits back on another. This permits both ends to talk and be heard at the same time (except for the human difficulty in doing so) but it also means that without extra switching each side would hear background noise and side conversations not intended for them.

The return link from Apollo solves the problem very neatly with a simple switch on each astronaut's microphone. Unless the switch is pressed (PTT mode) or turned on automatically by a sufficiently strong voice (VOX mode), silence is transmitted.

But this doesn't work in the forward link to Apollo because there's a long series of analog telecommunication links from Houston to the ground uplink site, and these lines add noise and crosstalk that would otherwise be annoying to the astronauts. So the Capcom sends a special tone burst at the beginning of each transmission that is picked up by a detector at the uplink site and enables the audio path to the transmitter. When he's done, a slightly different (lower) tone burst turns off the audio path, and the astronauts hear silence.

This function becomes utterly obvious from even a few minutes of listening, but the person making the claim you refer to seems utterly immune to reason.

Ah thank you ka9q, now i understand what this person that made this video about Quindar tones was trying to say or prove.You have made a good case of highlighting flaws in this persons reasoning, cheers.

Welcome to ApolloHoax, az09.

You have some threads back at DIF that have been mostly ignored by the users there, maybe you could present some of that information here.

[ka9q]

Quindar tones are a good example of something created to solve one problem that inadvertently takes on a secondary function, so when the original problem is fixed in another way and the technique removed, people ask for its return.

Quindar tones were added because telephone circuits in the 1960s were all analog, and subject to considerable noise and crosstalk. The Shuttle introduced an all-digital voice communication path, which didn't have these problems. But the astronauts found that they liked the Quindar tones as indicators when the Capcom was speaking, so they were put back on.

A similar situation occurs in ham radio FM repeaters. Early repeaters repeated the "squelch tail", a burst of noise that a FM receiver makes between the time that the signal goes away and the time the squelch closes. This was eliminated by various circuits that either speed up the squelch or run the audio through a short delay line to allow the squelch to see slightly into the future. But many users liked the squelch tail as a "go ahead" indicator, so the repeater controllers reintroduced a short beep tone, known as a "courtesy beep".

'roger bleep' as we called it.

Would love too, if you could kindly point out the posts you are referring to i will take it from there, cheers.

Sure! DIF is experiencing a dorsal-ventral inversion again, and I have to make a bunch of pie, but I'll try again later.
