Still can't believe they let us walk around on the old satellite dish, although apparently they used to play cricket up there!

New subscriber from Tom Scott.
Honestly, your almost-too-professional-for-this-age style is so refreshing. The biggest compliment I can give you is that you remind me of Carl Sagan.
He likes CGP Grey, and was introduced to me by Tom Scott's January break full of wonderful creators! Thank you KZread gods!!!❤️ Really interesting videos and a wonderful way to present mate! Hope you get much more attention, that you justly deserve, in the future!!

0:55 WOW. How have I never seen this before? I've never even considered why the two are always perpendicular and not e.g. in the same plane. Such a great animation

That was a phenomenal explanation of radio wave transmitters and receivers, I feel like I finally understand it thoroughly.
0:55 I think this is the first time I've seen someone properly explain how EM waves are generated. And I have a STEM degree lol. Also came over from Tom Scott, been watching through your backlog the last few days

I was absolutely blown away by that animation. I also had to pause to exclaim my excitement when the host explained AM vs FM information coding. "I studied physics for 5 years and I didn't know that what those stood for!"
0:47 I can't believe that none of my science teachers have ever explained electromagnetic waves this way. Thanks mate. That was such an elegant explanation..
I've seen a lot of physics illustrations in lectures and youtube videos, and these are some of the best I've seen. Very intuitive and stylish
Such amazing production quality for a small channel, you deserve to hit 1mil this year!
me again. this channel needs to be more visible to the algorithm
I'm so glad Tom Scott hosted you on his channel! If he hadn't, I never would have found this channel or any of its wonderful content. I look forward to the next video!
Wow! Congratulations on 37K, keep up the good work!

One word to describe this video and this channel: STELLAR! 😁 Keep up the AMAZING work! PS: The subtitles are very very appreciated. One of the key qualities, I believe, of a great channel is that it provides amazing subtitles and to see such a small channel with such high production value is utterly mind boggling! 👌 Thanks to Tom Scott for brining me here and thank YOU, the team, for making these videos!

There's so much here that I didn't know I didn't know! Particularly how exactly the shapes of antennae/dishes spread/compress the waves, and the difference between amplitude/frequency modulation
Hey! So excited to see how your channel evolves and it's nice to be part of the community relatively early on. I'd love to help out with audio or anything related to France if there's ever the opportunity. All the best !
7:19 nice pun with astronomical! If I had not already subscribed after seeing Tom Scott’s video that definitely would have gotten me to do it lol.
I just finished watching all videos of this channel. amazing work. thanks to Tom Scott for introducing me to your amazing work.
I can tell this is the type of channel that’s only going to bet better with time. Love the content!
Damn the production value is so good! I can't believe this channel doesn't have a million subs or more, it definitely deserves more

Amazing video, amazing explanations, can't believe I haven't seen you before and can't believe you aren't getting the rows you deserve.... Keep it up! I know I'm gonna keep watching!
This is the most intuitive and comprehensive explanation of what radio waves are I've ever seen, and I went to tech school to study radio transmission theory
Also, a very good explanation of the difference between AM and FM radio.
I'm amazed how brilliantly you summarize those topics and include surprisingly good visuals.
Man, your at 38k subs and you're making content I'd expect from a multi-million sub channel, keep up the good work and keep up the quality content. I look forward to seeing when your channel gets big.
Thanks for traveling quite a bit for us!

How didn't I get this in my recommended tab earlier? This is amazingly done!
These are the best visual representations of how radio works that I've seen :0
Guess you just got a new subscriber :) What an astounding production value. Keep up the awesome content!
This is really interesting, thank you! I grew up close to the ASTRON and the old CAMRAS in the Netherlands, but somehow never really grasped how it worked. Now I know! And man am I jealous they let you up there!
This is my new Favourite channel. Love it. Absolutely brilliant.
You’re a great teacher. Keep it up!
6:30 This is Parkes Observatory or DSS-49. I also like how you can see at 4:44 the old ESTRACK Antenna base right above the horn antenna. The dish itself now made it all the way to Santa Maria.
Atomic Frontier had 3.65K subscribers on November 11, 2020. On January 14, 2021 (~2 months later) it's become 37.4K subscribers! 100K by March?
Scoot beamed me over too. Thanks to all involved. Nice video...
Unreal channel. Saw you on Tom Scott and am an avid follower now!
Thank you KZread recommended algorithm...this channel is great!
Thanks tom for introducing me to this channel, great stuff so much simpler and easier to understand explanations
This channel is the treasure I got from Tom Scott... Great work mate 🔥🔥🔥
Still very glad i got to find this channel through Tom Scott! Very educational and intersting! Keep up the good work 💪
Thanks for captions!
wow, love this video! the format is perfect for me and its such high production value!
During Apollo 13 the Honeysuckle Creek tracking station near Canberra couldn't pick up the LEM's faint radio signal. The engineers managed to reconfigure the dish of the Parkes Observatory to receive the signal from Apollo 13, helping in the rescue of the crew.
Best channel I've found in years
cant believe a 70k subscriber channel has such well made videos.
You should have 1M subscribers! I really like your explanations. Thank you
Just watched the work you did with Tom Scott. And this video. Great work.
very glad i found this channel!
I remember checking your channel right after Tom Scott uploaded and swing you had 5k Subscribers, Wow you've grown quickly
Your content is great and well presented, this is a great example of effective science communication! Keep it up!
just has i'm done watching the rests of your videos. Great timing!
Fantastic video and explanations!
Absolutely wonderful presentation and filming. Your ability to communicate details is exceptional. So glad Tom Scott introduced me to this channel. Looking forward to your next video.
I assume you know where i come from, but man am i happy i found my way here, and also engagement so you can educate more people.
I'm very glad I've subscribed. You're videos are really cool.
So informative. I love it.
Just finished watching every video, I cant wait for more!
Fantastic quality!
Good lord that Hello Internet jingle hit me hard in the feels, since it looks like they're done with the podcast altogether now.
First time I've seen this scoop. Awesome!
I you were a stock i would put all my money in you. Guarenteed you gonna get 1 Million subs this year.
this is one of the best explanation ıhave seen about of how radio works. ı think you make a great research befor making this video.
What a good channel
I'd love to see a video on polarization, effects of the ionosphere, etc.!
Wow, great content and a Tim. Instant sub!
I found your channel though Tom Scott’s video and I love your content!!!
Excellent video, never seen a horn antenna before.
I hope the HI-atus isn’t affecting your outback drives as of late! Absolutely beautiful explanations and visuals

Neat video! But there’s more to radio than just AM and FM, there’s also phase modulation, which is arguably a special case of FM. Then there’s composite techniques, like quadrature amplitude modulation, which is used in high-tech radio protocols like wifi. The thought that FM carries more data than AM is mostly misguided, both have a data throughput proportional to their bandwidth (measured in Hz) and their signal to noise ratio, as per the Shannon-Hartley theorem. Same for noise immunity, to some extent. FM broadcasting stations are at higher frequencies than AM stations, and so they have a lot more bandwidth to put the same audio data through. If you crammed the same data in AM and FM channels of equal bandwidths (say, 44kHz), with the same SNR, you’d get similar levels of fidelity. Interference from lightning and such would effect both modulations, but in different ways. QAM, which is a form of AM, is used for higher speed wifi protocols, but when interference over a certain level is detected, I believe it switches to PSK, phase shift keying. If you’re interested in low power long range radio, look into LoRa.
You left out phase modulation, but that is probably going one level too deep. It is mostly used for space comms. Because the amplitude modulation can suffer badly from noise, and the frequency can change a lot (Doppler shift), but phase modulation is effected less.
Amazing content, earned a sub my guy

Content is great, audio is great, the number one thing to improve is the video. For example the focus, mininmal colour grading and white balance, exposure (check how your face is exposed, often too bright or dark), and especially choice of lens. Usually the field of view is very wide, your face is hard to see at all. I have no doubt this will keep improving with more experience though!
Great video mr dingles keep it up
7:08 one of the few times in history of the internet where you can say the sizes are still to scale
Tom was right, this does feel like an early 2000s BBC documentary
*nitpick* 5:15 when moving the bulb, you're not changing the amount of light being emitted, but you increase the volume of the cone the same amount of light is being emitted into...
