Oh, no! I butchered the name of our hero engineer. He's Frank Landspurg (not Dave Landsman). After a long carreer at Motorola, he passed away in 2014. His obituary says that he was most proud of his supporting the Apollo missions. We are very proud of him too! If anyone knows any of his surviving relatives, let us know!
Amusingly carrier works so well in this case and I appreciate two things here, one is that you speak in English for us and two, that career and carrier sound much the same when you say them. I love what you do on this channel and sit open mouthed through most of the episodes.
"CuriousMarc here, we managed to get ahold of five F1 engines, so we're going to see if we can get our restored Apollo spacecraft to actually land on the moon"
@@twotone3070 The process of activating the damaged heating element in the cryogenic oxygen tank (colloquially "stirring" the tanks) is what triggered the cascade failure that crippled the service and command modules on Apollo 13.
He’s our hero. Unfortunately I butchered his name in the video, he's Frank Landspurg (not Dave Landman). He passed away in 2014 after a long carrier at Motorola. His obituary says that he was most proud of his work for the Apollo missions. I'll pin this info as a correction.
I hope Mark Watney has added you to his contact list. This is a blast from the past my grandfather was one of the engineers that worked on comms at Colins radio in IA in the 60’s. We would often go outside and watch the moon. He told me we will be able to talk to people as they walked around on the moon. I was 5 years old and its a memory that I will have forever.
Every single one of these videos, I am amazed at how much technology we had even back then. You guys have done absolutely fantastic work documenting this and demonstrating it. Without this series, there would be a big void to be filled, that would probably never see the light of day. Thank you so much for this.
It came a long way since Marconi. That was the peak of high frequency analog communication! Soon after, digitization started, and now we are working with SDRs.
Each generation considers itself the smartest of all but when you look in the past carefully no fools gave us the basis to move up... We are standing on the shoulders of giants.
This takes me back to studying Morse code as a child: ".... . .-.. .-.. ---" I actually ordered and checked out a training manual on vinyl record through the inter-library loan program and had to wait a week or two for it to arrive. I might have to pick that hobby back up again.
Now you lot just need an Apollo CM to put all that hardware into. It's awesome watching you all restore this equipment and teach all of us how it works in the process. Thank you!
This is exactly what should be done with all the dusty space and computing equipment floating around museums. Almost everything could be revived with time and effort. I think this is one of the most important projects on RUclips.
I'm sure 100 years in the future, someone will say the same thing about the P-Touch label in comparison to the 3D holographic video labels used like we do QR codes today.
I was the a/g comm tech at the Guam tracking station. My job was setting up UHF links for them to talk confidentially. If you have any questions please ask
Well, I know what I'm watching first thing tomorrow morning! Our Apollo communication engineering dream team repairing and demonstrating 50 years ago technology, that we love, in a way no other could explain!
Absolutely amazing work, I came across this channel completely by accident and I'm glad I did. Your knowledge is amazing and the equipment is breathtaking, these videos far surpass (at least for me) any documentaries I have seen about Apollo. It started as a coincidence and today I regret that I cannot be at such a great project in person. Thanks for the opportunity to see this project at least with YT. I wish you a nice day and a pleasant Christmas 🙂 Tom
I don't have the same amount of kit and test gear but I DO have the same Icom 7300 ham radio the team are using so I have a strange glow of pride and kinship 😂
I didnt understand most of this but still think its brilliant that you guys go to this level to bring the Apollo hardware and software to life again. Fantastic!
Marc you and your team continue to amaze! Thank you for your hard work, repairing and demo'ing this wonderful hardware! THIS is the best site on the RUclips platform!
Excellent work, as always. It's pretty mind-boggling to see what went into just radio communications to/from the moon. Nowadays you could probably get the downlink going using a digital TV tuner with an overinflated ego, AKA an SDR.
I know that there is so much research and work that goes into all this reverse-engineering but I must say that we all appreciate these historic efforts. It is one thing to look at a bunch of legacy hardware, talk about it and lament it passing; but it is a whole-nuther thing to bring it all back to life for all to see. Very commendable effort, and you and your team should be very proud of these exceptional achievements. Also, telling the historical story is admirable as well. Thanks Again & 73...
Excellent work untangling the RF for the voice downlink... Who would have thought back in 1969 that you'd be working on restoring the equipment here in the SF Bay Area? It is a pleasure to watch every episode! I feel this work is historic in its own right and I'm glad to be here to witness it. P.S. I was a little boy at the time of the moon landings and didn't understand the significance, now that I do, I just love every technical detail of it. I had an opportunity to meet Buzz Aldrin on the USS Hornet for the 40th anniversary... And see the moon rock at Chabot Space science center.
73's🎙KD9OAM🎧📻📡 🚧 As an electronics technician from the US Navy that was in the Pacific for Apollo 11's splash down. Our shipboard equipment was larger of course, but we used very similar equipment and procedures, to what I see you operate and restore in this video. Well done!
im so happy i found this channel ..i wuv what ya'all are doing there ...rebuilding americas history ..the nasa tech our granparents made "with maw bell "is what built our world we see today ..that may be a tall staement ..but look no furhter than your phone ..to know i am right ..merry x-mas marc and your faboulus team :) happy new year 2024 is gonna rock! :)
You guys are the best. I am an Apollo nut, so obviously I love this whole series. Thank you for all of your dedication, hours of reverse engineering and your top notch debugging skills. You fix extraordinarily complex electronics, but I retain probably 10% of it. However I have learned SO much from your channel. Thank you for sharing your knowledge. And happy new year!!!!
Yay! I've been enjoying the videos from other projects, but had been hoping for another Apollo coms installment. This is a great early Christmas present! Thanks, CuriousMarc and team!
I see a lot of hp vintage test gear, be nice to see test specs, signal mds, selectivity, noise figure, min Snr needed, pll lock range, in any case, I'll gladly take your hp test gear after your Apollo videos wrap up. 😊😊😊
Love this, I was 11 years old when I watched the first moon landing. At 16 I went to work at Goonhilly Satellite Earth Station where the first moon walk pictures were received off the Intelsat Satellite for broadcast in the UK and for some parts of Europe. As a Radio Amateur I have some of the test gear you are using including the Nixie Tube Counter and the Spectrum Analyzer - love HP kit from this era.
What...? Did I hear Usagi Electric doing Eugene Cernans' famous "I was Walking on the Moon One Day" song? Oh no, he was probably doing a Japanese song 🤣 I love this series, you'll doing an amazing job. Great it's all taped for prosperity.
One very tiny detail that I found interesting is that the original equipment was marked in KC (well, MC in this case) while the modification used KHz. Assuming the 768 KHz label was original, that's a nice illustration of when exactly that notation changed!
My thirteen year-old self hardly gave the technical aspects any thought. It was just what was expected and accepted (shrugs shoulders). But now... ...and what is equally astonishing is that "they" are struggling to equal the achievement. ps Chapeau l'équipe!
To say your making progress would be a understatement. To say I spend half of my working life undoing modifications to radios would be a understatement. Seeing the modification documented in the equipment in my world a unexpected joy. You were blessed by the RF gods. Excellent work by you and the team. Curious, since I saw a modern amateur radio in the video are you a amateur radio operator? Mike KC3OSD
fantastic work guys, are you planning on remaking a mockup apollo cabin to hold all pannels & boxes in place without risk of ripping cables or unplugging/replugging connectors the wrong way? Would love to help if ever needed.
I had a horrible flashback to retuning a 6 cavity input filter on a (tube) Motorola VHF mobile. I had an Eico RF signal generator for a source. (And an HT to verify its frequency.)
Fast forward fifty years and think of a future-Marc restoring a present day spacecrafts electronics (Dragon?). I’m not convinced it would be this interesting. We’d be watching s/w debug sessions.
Hey! A piece of test equipment I recognize and own! That looks just like my HP 3312A function generator! (Though it may be a slightly different version, can't quite tell.)
One of the crazy moon conspiracy theories I hear is how the president was able to place a “phone call” to the astronauts. It was common place for Marine VHF and HF to patch into PSTN. Would be amazing if someone could find the patching equipment from the moon landings.
Hey Marc, Nice video. Are you planning to do anything with the Biomed data side of things? There is a guy called Justin who runs the channel Better Biomed who would be able to help you with safely supplying of ECG / EKG signals.
Sadly we don’t have any of the biomed encoding and decoding original equipment, but we could try. Right now we are just struggling to get updata decoded. Maybe in episode 225…

"CuriousMarc here, we managed to get ahold of five F1 engines, so we're going to see if we can get our restored Apollo spacecraft to actually land on the moon"
I genuinely think they would, if they had the parts and funds. lol
You just need three astronauts, and can go ahead!
Hahahahaha😂
Would probably do it faster, cheaper, and safer than Elon 😂
No need for five, with the new, updated computers and communication hardware you will save enough weight to use less F1 engines.
