Thanks for such a clear succinct presentation. You have very good teaching and comms skills
A fun experiment is to compare uncorrected scans where the galactic plane crosses the ecliptic captured near the equinoxes to measure the orbital vector magnitude and therefore measure the distance to the sun! I managed to get within 3% of the actual distance using this method from my backyard!
I am eager to learn more about what amateurs can do in the field of radio astronomy and I've found your videos informative and inspiring. This is great work and I'm very much looking forward to the next episode. Thank you also for the accompanying links.
Brilliant video, hope you have a whole series of these planned, discovery's, findings etc...this is absolutely fascinating and expands on the normal visual astronomy were flooded with on UA-cam ❤
Simply wonderful, the best practical information so far. So much info is too basic to do anything with or so complex you could build a star ship. 🤣
Thank you very much and you should make a radio telescope kit "book" and sell them at Barns and Noble. 😎 Please make more helpful astronomy videos.
An interesting note, I created a spreadsheet to calculate the combined LSR vector based on a date entry. I discovered that in late November, the LSR vector almost exactly aligns with the galactic pole making the doppler correction projected onto the galactic plane nearly zero!
Very well done! More videos please.
The Virgo Software looks to be really worth a look.
I am going to try it out ! Thanks
I realized that by the time I finished this video, I traveled over 26 thousand kilometers. I've gotta take a nap. Thanks for the great info. I've been reading Garrett M. Graff's book, UFO, THE INSIDE STORY OF THE GOVERNMENT'S SEARCH FOR ALIEN LIFE. He frequently discusses the attempt to recieve extraterrestrial signals via the hydrogen line. Your videos have helped me better understand the concept. Thank you!
Really enjoying your content! Teaching with one manageable bite-sized project at a time is such a great way to tell the story of astronomy. You are doing really great work can't wait to see more!
Hey Kevin, your videos are super awesome and so helpful learning radio astronomy from scratch! I gonna build my own radio telescope from the infos I gathered from your Channel! Keep posting more videos! Thanks 😍
every now and then youtube's AI actually suggests stuff that (i think anyway) is really good. thanks photonic
Good explanations - very clear! Thanks for sharing.
Wonderful, 🙂
Cloudy night fun!
This is such a cool project! A definite standout
Great video, simplistic explanation & a good starting point for amateur radio astro. Keep going!
Been excited for this video for a while, glad it is out :)
i stumbled into your channel and I noticeed that its been two years that you have posted a video. I liked it anyway and I am wondering if you are going to make any other video
É incrível sua explicação, continue fazendo seus vídeos, estou construindo o meu radiotelescopio.
We are waiting for Pulsars!
HA!... a SmartPi case! I just got one of those
PLZ MADE MORE VIDEO
The LSR(K) data velocity correction factor varies continuously. It is dependent on the Observers Long/Lat Location on Earth / Date / Time / RA and Dec position of the telescope and can vary ~ +- 30 Km/Sec each day ( sinusoidal).
Ideas for a small Neutral Hydrogen ( H1 ) Radio Telescope Project ( presented this Summer : Society of Amateur Radio Astronomers conference SARA ) ua-cam.com/video/C6NCefVxNL8/v-deo.html
That's why I added code to the Virgo project that uses the time, lat/long, and other factors when calculating VLSR. Fortunately, the astropy library has methods that keep it from being too complicated.
By the way, thanks for adding the link to your talk. I missed the SARA conference this year.
@@BlueCordVideo Yes, that correction calculation is Not Trivial ! I initially used an on-line calculator w/ Excel to find a 2nd order poly fit curve. I now have a Matlab program from JJ Maintoux. Thanks for the ok on the link. Alex KK4VB
I wish I had found your presentations a year or so ago. Excellent Material.
One of the most difficult tasks in beginning Radio Astronomy is finding basic material .
Why parabolic antenna is preferred over elliptical antenna?? For astronomy
Excellent video. Do you have a source for the feedhorn antenna design? Maybe also a parts list? Just in case someone wants to recreate the project.
I used the guide published by Harvard (lweb.cfa.harvard.edu/~npatel/hornAntennaAASposterPDF2.pdf).
Can you do a video on setting up and using Virgo software with Raspberry Pi?
превосходно
Hi. Great video. I hope you are all right. My question is how to make the calibration file? Close the receiver input with 50 Ohm load is ok. But what is the command line command that needs to do? I read the Virgo user manual but I didn't find it. Please tell me the
Ух тЫ! Молодец! Давай ещё сделай исследования! Если дополнить твою антенну системой автоматического позиционирования, то можно с большой экспозицией следить за конкретной точкой в космосе.
что они ловят этим рупором?
Can I use a parabolic, dish antenna instead of the horn antenna?
Yes, as long as it is large enough. The small Direct TV dish I used for a previous project wouldn't work, but one of the older style satellite dishes would.
Hey dude I’m watching your all videos in 2024 why did you have stop making those video ?
Hi, What is the link to the first video you made in making the radio telescope? I clicked on your Photonic header but did not see the first radio telescope link. Thank you.
It is the video entitled "The Hydrogen Line in Radio Astronomy" (ua-cam.com/video/IXFq02OK23s/v-deo.html)
Sir, I am using old computer.. It is not compatible with sdr software... So I am trying to buy new laptop... Can you give any suggestion(recommend) for laptop which in affordable rate..
Hey that's really cool. You are really knowledgeable. You are good. Almost like a Broadcast Engineer Ham. And it looks like you have had plenty. Of tickling technical courses. For your fancy. Radio Telescope.. That is so Awesome! Does it also get, C-Band Satellite TV?
I just love this! And were you the guy? That Broke-In, as Imitation Max Headroom years ago? I just knew it was you! We've caught you!
No I don't work for the FCC. I just want your Autograph.
And so you're looking for Hydrogen? You know we also make it on earth? Right? You don't have to go far. Not even 93 million. Sony can do it for less. No baloney. Even Toyota. If you're not certain about a Honda? But you meet the Nicest People on a, Honda. Jet. That looks really nice if you can afford one or two. The kind Joey O'Steen would get so he could Minister God on his, elaborate vacations. Around the world. In his own private Jesus Jet. Powered by Jesus. For, Jesus. With Jesus's's's official Emissary Joey O'Steen. In the, Image of Jesus. With a tie. And beautiful Teeth. With beautiful caps. His beautiful poor Social Security only existence, parishioners. All paid for. And also to keep mud off of his Jesus carpets. After about 17 of the 2015 Hurricane, survivors. Tracked some mud on his Jesus carpets. Forcing his poor parishioners. To pay $7 million to re-carpet the entire place! Because you cannot be getting mud on Jesus carpets. Jesus said no! Do not do that to me on the floor. Of the 20,000 seat former NBA, MAGA Stadium Church. As it is also Lakeside. Lakeside Manor.. Lakeside, terrain. Terrain! Terrain! Pull up! Pull up! Terrain! And pledgor dollars today. To his flag. Of the United Church of Merica. And to their Reap Public. For witch it stooded. One Nature on to another. I declare my Country, Merica!
Who we! Ye ha! And the Kanye,, you came in on! Trumpy Wins Again! Before the elections! Woo hoo!
