It was very marginal, but it did work! I need to get my 2.5 meter dish mounted and set up permanently for this, just haven't found an acceptable way to bolt it to the roof yet 😅

Awesome! I've been using some larger dishes for GOES recently, I'll do a follow-up video soon. If you can find an old C-Band dish (the bigger ones), or even just a slightly bigger KU dish like the "Alaska model", that would hold up better than my cardboard and foil tape! Otherwise Nooelec sells a grid dish on Amazon if you have spare $.

I absolutely love this channel, your ingenuity and disregard for the prevailing attitude that X equipment is “required” to do Y job is inspiring. Brings me back to when I first got into radio and electronics and wanted to do everything but had little spare income and no tools. Every aspiring nerd should watch stuff like this to realize that the underlying principles are what should guide you, not a Howto that says you need this product and that product to get started. Admittedly you are using purchased off the shelf products like an RTL-SDR, some things are definitely better purchased than home brewed, but your “let’s try it” attitude with stuff like expanding the dish area with cardboard and foil tape, should be celebrated. Keep up the good work!
Those totally work, and hobbyists actually use them for the second signal this satellite puts out. The signal captured in this video only puts out a fraction of what the satellite captures, the other signal is much wider, and weaker so a larger dish is needed.
Your brain is amazing... I hope you work in this sector if not you should get into it . Atleast get into teaching smart children to do this stuff we need brains like yours in this point on the human time line o wish I found someone like you doing this stuff when I was a kid
Very cool!! I was messing around last summer with a dish like that for GOES, but I never thought to slap some extensions on it like that! I'm currently building a collapsible umbrella dish out of a photography light reflector and some conductive fabric. Hopefully it will go well, it's awesome to see how such a simple fix yielded great results for you!
To do something like this long term.. look into getting a NAS, Network Attached Storage.. A mini one holds four hard drives and you can access the images and whatnot over the web.. basically its a file server and depending on the capacity of the drives you get, you can store well over 8TB of data
Probably, if you swap out the TV LNB for a feedhorn / cantenna tuned to the right frequency. I also have an old C-band dish I'm hoping to use for GOES soon!
I was so inspired from this video that I got my old derect tv dish out and got to work but I’m struggling badly I have all parts just have to figure out how to put the cantenna on Dish and make the dish bigger
There are a few websites out there with info about making and positioning the cantenna. I think I liked to a couple in the description, or this is one: lucasteske.dev/2016/10/goes-satellite-hunt-part-1-antenna-system/
I've been attempting this with A NooElec mesh antenna, a Sawbird+ GOES, and a NooElec SMArtee RTL-SDR, but try as I might, I'm not even having any luck even seeing the signal on the SDR# waterfall. I'm nearly certain I'm aimed where I'm supposed to be aimed, but I tried adjusting it left and right up and down gradually to see if I see anything pop up. I've had success in the past receiving those polar NOAA satellites with rabbit ears you mentioned, so I'm not a complete n00b at this sort of thing. At 4:24 you say you can "just barely" see vertical lines in the waterfall at 1694.0 MHz. Maybe the UA-cam compression is messing with it, but I'm not really seeing anything. Or are the lines you're talking about super faint and coming down from about 1693.5 MHz to 1694.5 MHz? Is it that wide a signal? Also - (If you can recall, or make it out from the video) do you remember approximately how many dB above the noise floor that signal was with your make-shift setup? Any help would be appreciated, but I understand you're a busy guy and might not have time to reply. Not a big deal! [my apologies for the lengthiness of this comment] [btw - Big fan of the channel! I've been checking out your stuff for over a year now, and really enjoy the "Just get it to work with whatever I've got" mentality. Greetings from northern Illinois!]
It is a pretty wide signal, depending on your SDR software settings you might not see the whole thing. I think I had to increase my sample rate to get a better view. Here's an example: www.sigidwiki.com/wiki/GOES_High_Rate_Information_Transmission_(HRIT) I don't remember the dB or much else about the technical details, it's been a little while since I did this. I have some other dishes I want to try, and I keep meaning to set up a permanent ground station for this. Just need to find the time among all my other projects! I do remember that getting the position just right took some fiddling. There's azimuth and elevation, and IIRC a skew angle (rotation of the dish / feedhorn). Plus the cantenna/feedhorn has to be at the focal point of the dish and any extensions. It was one of those things that I eventually got right with my garbage set up, but wouldn't last a light breeze or rain! That's why I want to use a real dish and a solid mount of some sort.
So did you ever find a c band dish? For easy way to get one is drive around the country side and you can usually pick them out and stop and ask them to see if they want to get rid of it for most will give away free if you take down. For that's what I did for my FTAsatellite I acquired a 10 ft unimesh dish that's motorized. And I use it for fta TV like wwe wrestling on 55 west and the nasal channels in 127 west. I'm trying to get goes 16 with the noutec dish and sdr but having issues with software to decode it.
I did get a C-band, yeah! It was full of hornets but I got it home and now it's junking up the yard and lowering my neighbor's property values :-D I haven't installed it yet, need to wait for spring.
@@saveitforparts what you should do is set it up with if it's motorized is install a new digital c band lnb and install a can antenna next to it on the side of the lnb so you can use it for FTAsatellite and goes satellite for c band fta has more to offer than ku band. You will need a 36 DC volt power supply and a control box like what you used for your goes dish or if you can find a used vintage satellite positioner in ebay for that's what I use to move the dish. Grease up the actuator also if it came with one for it will work better with fresh grease. Good luck.. robbie strike on UA-cam has good videos set up FTAsatellite

This one is a PTZ mount for a security camera, it's a Vicon MicroPan, model V3000APT. It isn't quite strong enough for the dish in all orientations, but it works OK.
They did quite a bit, the dish is too small to pick up the GOES-E weather satellite by itself. With the cardboard and foil it can just barely pick it up, and I was able to download weather data. It's not a good permanent solution since it's not weatherproof, but it was fun to make it work!
Yep, there are two active ones and some backups, I think they move the old ones around a bit to cover Europe and Asia sometimes. I'm hoping to do this again, but with a permanent dish instead of just cardboard and foil tape!
@@saveitforparts how did you get Sdr ++ on raspberry pi One more thing goes tools is now available on windows posted in July of this year, I wonder if you could try goes tools on windows because I’m having trouble with it
Do you need a smaller dish or bigger ? I have a portable dish in a case if you want it for free . It’s about 12” round and on its own brackets and case used for RV’s . Let me know and I have a couple of satellite meters for aiming the dish .
It depends on your equipment, some LNAs feed power back the wrong direction and need a DC block. I only came across that while reading about other people's setups online, I don't know which brands are better or worse for that.
@@saveitforparts If your going to all the effort of adding "sides" to a small dish, why not just try and make a choke ring antenna for this 1.6 ghz frequency and forgo the dish alltogether. choke ring antenna is pretty much a c band feedhorn WITH the scaler ring. So its like your cantenna with concentric rings. Very cool video, and effort
@@jeremycole3008 Interesting, I'll have to look into that! The signal from the GOES satellites is so weak that I think a big reflector is needed, but maybe that choke ring deal would work at the focal point?
@@saveitforparts Im thinking this: Speed of Light is 299,792,458 m/s in Air or Vacuum. If you assume the velocity in Aluminum is 95%, you get: 284,802,835.1 m/s. That number, divided by the frequency of 1,686,600,000 cycles per second, you geta full wave (in aluminum) of .16886211 meters or 168.862 millimeters. 25.4 mm per inch gives 6.6481 inches. The ring thickness is 1/4 wavelength, and the spacing between rings is 1/8 wavelength. 1.662 inches tall, and .831 inches inbetween. My CBand scaler ring measures an 1.08 inches tall and 1/2 inch wide, so I think these numbers should be good. The CBand feedhorn is 500 Mhz wide between 3.7 Ghz & 4.2 Ghz, so the accuracy of these numbers might not even be that critical
It's an offset feed, most modern dishes use that design to save money since they can be smaller. Think of it as being only the top 1/3 to 1/4 of a traditional satellite dish, the focal point is still in the middle but the rest of the dish is missing. www.datawelder.com/satellite/sFAQ/sfaq.html

you need to fix your Earth Model, the North and South Pole are tilted ... :D
I threw an old dish in my truck this morning lol
You DO KNOW how to make a satellite dish out of CARDBOARD and ALYOUMINeeeUM TAPE don't you! 👍 They work grrrrrrreat! 👍

Is that Khan in the U.S.S. Reliant circling the Earth? We’re screwed.
Ditching this beard was a right move
I've come to hate raspberry pi's so much good software has been made only for them but they are extremely expensive and I could buy a fully functional laptop or other much more powerful computer for 1/3 the price
Wrath of khan vibes with the globe demo.
Khaaaaaan!

Ok, we need a "solar rover" that we can control by "satellite" that we can send TO THA MOON ALICE! 👍😜😆😁👀🤣
Very impressive! Now you can move on to a more practical application......stealing cable tv channel signals for all your subscribers.
I have another video on free satellite TV, but all the stuff that's legitimately free (at least on this side of the planet) is religion and communist propaganda :-P
Hey, I build "ROCKETS" can we modify this so I can send a rocket to "NORTH KOREA"!? 😁👍
добрый день а возможно ли создать радиотелескоп по принципу вырыть в лесу неглубокий котлован , застелить котлован фольгой , и сделать антенну , самый главный вопрос как сделать приёмное устройство для прослушивания дальнего космоса и планет .
I suppose that's possible, if the pit is very precisely shaped! Interesting idea.
@@saveitforparts I'd love to see you give it a try! Even if the ground pit isn't the best way, just making a sat dish out of something a bit strange.
what is a ken tan
You mean a cantenna? It's the feedhorn made out of a tin can. Commonly used for WiFi, you can find more info and calculations for different frequencies on Google.
