Some behind the scenes chat about the Canberra Deep Space Communications Complex.

Dave - I'm sure I speak for all your viewers in asking you to pass on our thanks to Richard for taking the time out to host you and to patiently explain the details and to throw in some many anecdotes and stories. These videos are some of the most illuminating and fascinating ones I've ever watched.

Sure, just stick your foot between a telescope with the mass of a large office building and the asphalt just to see if you can feel it moving. Heck, I love the casual nature of your meet-up. Makes me so happy to see people meet who share their interests and professions. A rare sight on YT, especially in this field. :)

Bloody brilliant! While I am quickly bored by long-form interviews, this casual "while we wait" chat is beyond fascinating. Let Richard ramble, then insert relevant questions as needed to keep him rambling on. I've only been to Canberra once while driving from Melbourne back to Sydney, stopping only for lunch. I evidently stopped at the wrong place. I'd love to be a fly on the wall in their lunch room.

Nice to see Richard is a RPi fan

[@zapfanzapfan]

Fantastic guide!

[@CarstenGroen]

Great video Dave! (and Richard is an excellent speaker, very interesting to listen to!)

[@paulloveless9180]

KC8SGJ here. Watched the entire series. Farking brilliant content

[@hoofie2002]

Another fascinating video - well done

[@rfengr00]

Nice video. Good to see the actual dish for Apollo landing. The one in The Dish is an observatory.

[@WouterWeggelaar]

Thanks for posting this Dave! I thoroughly enjoyed it. When I heard the word ITAR I cringed a bit. Funnily enough I partially owe my job to ITAR, because people that do not want to have the ITAR hassle come to my company for alternative products. I build satellites and ground systems, and the US has lost their edge to the EU because of ITAR... Regarding the question at the end: I some times feel weirded out when I come to work because it hits me I am building satellites. We specifically build nano satellites, and we work small teams, so everyone gets to enjoy a lot of the technical challenges and achievements!

[@sparkplug1018]

Even though RF and communications systems are a bit beyond my understanding, I really enjoyed these videos. You all are great presenters that really know your subject.

[@philno]

i do love these vids dave

[@LevonAvagyan]

Oh no! I wanted to see klystron tube! :-D Great video! Thanks for sharing!

[@EEVblog]

It's in the other video.

[@douglaskoo2354]

that's very informative !!! keep it up

[@Tore_Lund]

Absolutely marvellous. The amount the technical details in these 5 videos is gold. One thing never answered though, is how does Voyager 2 aims its dish? Is that taken care of from Canberra too, or is Voyager 2 taking care of that autonomously? I know the Voyager probes had an attitude alignment system that follows a few stars and the sun, but is that still sufficient and still working?

[@SirDoomwalker]

Thumbs up! :)

[@RobertSzasz]

Could they use the antennas as a phased array transmitter? Reuse some techniques from MIMO to connect to multiple craft around another planet?

[@EEVdiscover]

We talked about that but didn't get it on camera. It's possible.

[@frogz]

dont know why this is so facinating.... did they let you take home any spare equipment to play with? lol

[@FurrySergal]

Hey Dave! This might not be a popular request but would be extra trouble to upload a relatively uncut \ unedited version of each video? Not sure if that's an unrealistic request or not.. I just like every little detail personally (:

[@EEVblog]

I've included everything of value now in all these videos.

[@alphanimal]

So what's the difference between no enough power or not enough gain? From my understanding power is energy/time, gain is just a ratio for increasing the power by a certain amount?

[@17plus9]

Same input power / different gain.

[@Mythricia1988]

It's about focusing the available energy into a smaller area (smaller cone), so with the same power you can get more range (more gain in a specific direction), for example. Poorly explained, but that's as far as my own understanding goes.

[@kissingfrogs]

Didn't quite catch it at 2.22 Rides on an oil layer 7000 ???? thick.

[@ZsoltBottka]

rides on a film of oil, 7 thousandths of an inch thick (.007 inch or 0.1778 mm)

[@kissingfrogs]

ITAR I promise I will look away

[@axeman2638]

Lol Dave still thinks NASA landed men on the moon 50 years ago and that we still haven't been back despite all the advances in technology. Pretty dumb for a smart guy Dave.

[@alfoncejean8826]

well what you are implying is even dummer. So I would not worie about Dave....
