Absolutely FABULOUS!

the GPS satellites have workers inside who maintain the electronics . they need to call home and talk to their families !

WTF. This video totally made my day. Knowledge combined with a (maybe, non intentional) humor. I'm dying haha. The fridge server

You've really got that construction method dialed in - nice!

I want to visit you

hi sir. i would like to know about how many music choice radio station ku band have? thank you.

what a bunch of crap

Good job with this design, I know this is an older video but I built an helical antenna last week-end and it's really good. It's so light and has good gain. For hand tracking I think this is the perfect little antenna.

Love the "Russian warship, go f*** yourself" on your 3D printed antenna 😊

Hi,I have a few questions:can I pick the proba-2 satellite from Italy,Sicily?I don't think I'll be able to pick hinode or gac from here.Have you got some informations about other satellite that I can pick from here in S band?Because I just finished my setup (I'll try my dish and my wifi grid to see which has more gain)but there arent many satellites with useful data.Jason 3 some says that it only dumps now,and cloudsat and coriolis got decommissioned.Also,do you know if Elektro l-3 is currently transmitting?Because I can pick only the beacon in L band.

@7:00 lol

pretty cool stuff. I do want to get the clone hackrf because I don't feel like spending about 380$ on a real one would be a good financial decision. I know this is an older video but comments are always good for videos! Keep pushing, you are probably open the path for the future x-band amateur satellite community

Found your YT channel yesterday, been watching ever since. I've spent several decades in RF design etc, you only really learn by experimenting (and importantly failing), it's how our brains work. So don't ever think that any project that fails or just doesn't meet expectations is a waste of time and effort, it isn't !! .. you learn something new EVERY SINGLE TIME, plus you gain the all important EXPERIENCE, keep going ! .. By the time you're my age (60+) you'll have amassed a great deal of knowledge and experience to be able to do just about any project you like.

what is it used for?

Hello bro i m from india whe mostly use inverto lnb in our contry plz make a vedio on indian lnb and urs one.😊

Can you receive s-band signals (especially 2200mhz and above like proba, noaa poes hinode)connecting only the ham it down to the antenna and the RTL-SDR if not what LNA are you using on this video? So far I've tested the ham it down without an LNA with the L.O at 1500mhz on satdump, it picks up signals at 2450Mhz without any problems, so i guess at least it works

This is what you call: cosmic horror.

Great video, do you think a helical feed would work with this dish. 🤔

Why do you need a motor? Can't you just put them into position by hand and let the rotation of the earth move them across the sky?

You should buy penetrating oil, you can buy in diy stores like OBI. Works much better with stucked threads than WD40.

Use break cleaner!!

4:35 ~~reunification? more like annexatio~~ --I mean yeah, no way, Germany is finally united n stuff...

Ambitious! A great community ready to help! Keep us updated

If you want a non destructive way af adding leverage on initially freeing the shaft, you could try a jar lid opener. The lid opener comes with a belt that you strap around the handwheel and a long handle. When you pull on the handle it tightens the belt gripping the wheel and this gives you quite bit of leverage. This just in addition to the oils, wire brushes and heat thats been mentioned.

Remember about polarisation signal changing by different voltage bias, upling and downlink can be on opposite polarization angles

Love it! As others have said, WD40 is not a lubricant. Using a 50/50 mix of automatic transmission fluid and acetone is one of the best penetrating oils you can find. Adding heat with a torch or inductive heater is a great way to break stuff loose as well. I'm interested to see if you run coax or use a wave guide and how you plan to phase each dish. Which mixer/differential amp setup do you plan on using to filter out the noise?

Hi, very interesting - I'm looking forward to seeing how this project goes!

PS i see the threaded bolt is connected via 2 large square nuts that are connected to the dish mount disconnecting one from the mount you can now get a shifting spanner or stillson Pipe Wrench on it and try and move it up and down the thread ...it will be a bit of work but very possible ! again a hammer or mallet hammer would come in handy if that wrench still won't move it ! Gease keeps better lubricated longer than wd 40 . Again on the motor side i think a hand drill with its gearing would move that dish a stepper motor is a good idea but you need still gearing and how to connect it and all that a hand drill the only problem is the the bolt might be to big to fit in it , you could grind the the end section of the threaded bolt down till it fits in your drill ! Just then need a bracket to the mount so when the drill is working the drill case does not spin,pretty much like the home made actuators i have seen using a hand drill !...Yes you are right from my gate opener on my dish as a positioner it is harder to move the dish more force wise needed either end on the maximum low positions to back up moving position ...The gears in the Drill should still be able to handle what i see if you can move it by hand the drill sure will too . If all this works you can build a power supply for the drill and put timing in to start and stop it lots of ways to do this depending on your timing wants to move the dish . A drill is a very cheap solution as they can be found second had due to the battery or its charger is broken and of cause bigger the better ! ( stronger) i would go looking recyle places or on line should cost you either nothing or 10 bucks good luck watching with interest .

HI last year i got a second hand C band dish and it had been sitting in the one position for over 20 years so the elevation adjustment was as yours stuck with rust . Getting mine to move was a bit easier i used as others have mentioned a wire brush first to clean the rust from the thread and wd 40 as you but i used also grease ,i have 2 large nuts either side of the elevation adjustment so large shifting spanners and a hammer wacking those at first does work till the nuts start moving . I can't tell from your video as you were moving around a bit when focusing on the problem area if that large round adjustment has a place at the end to put a spanner you can do what i did if not i would remove the whole adjustment and put that large round hand adjuster in a vise and again do the same me and every one else and work on the thread and make it move via the other end once working put it all back . If you are planning motor control there are lots of videos on how to make a Actuator from a long threaded bolt and a hand drill ! I was given 2 old dc geared gate openers and have used one so far moviing my 2.5 m C band dish polar mount azimuth control , BTW great video very interesting love watching your work with satellites and the dishes ,the reason i have one now my self is due to you !

It's a cool project, but I think you'll get bogged down in mechanics. Why not focus on the electronics and the capture side of things and just move the elevation by hand every day? Seeing it actually work will give you motivation to then work on the mechanics, or maybe someone will sponsor a proper linear actuator for you. I think it's a much better way than starting with the least rewarding and toughest part. Good either way 😊

Carry on. This is amazing

Pleas dont Put any weight on the dish. You could bend it out of shape. Just clan the threads and soak them with some light oil like WD-40. After you freed them up I would grease them an use something to protect the threads from the elements. Maybe a fork boot cover from a motorcycle could work. For the motors I would try some nema 23 steppers (or bigger?) with a angle gearbox.

the interference could come from the laptop and/or camera, I don't think it could be anything else. I also think that the antenna can be even better by making a closed dipole! ( here in the Netherlands they also make and use closed dipole for 85MHz WFM ) it is also less sensitive to interference.

Only Czech aircraft - are you in Czechia? Edit: Nvm, saw the Grippen.

What happened to your own 2 mtr something dish ?

B Tak jo!

... тебе прислали SDR, который ты хотел?

Car parts to steer it literally. Worm gears, diffs, a steering wheel and an arc welder?

Look at me everybody, I own a potato! Was this thinking last night, where's my mate Derek at? Ahh, he's been busy out getting the keys to the universe. What amazing projects and potential man. So looking forward to what comes next. Car parts to steer it literally. Worm gears, diffs, a steering wheel and an arc welder?

Let's go!! I passed my struggle with acquiring H-Line with DIY radio last year lol. Currently building an Alt-Az mount for the dish (the dish was cheap C Band dish that now already has a lot of holes due to how thin the mesh is, lol), previously used an optical equatorial mount for "temporary data retrieval" for the dish. I used Nooelec Sawbird+ H1 amp/filter and a cantenna for the feedhorn (that simplifies things!). For software, I use SDRSharp with IF Average plugin, it's outdated but again simplifies things when you are trying to acquire your signal for the first time. SDRAngel is much more capable software but I found it not user-friendly and hard to use. Wish you luck with this project!

Check out one of the RTL-SDR radio astronomy groups. You can find very inexpensive hardware and software setups, just add antenna.

Cool! Looking forward to more vids on this for sure. Heat, WD40, heat, WD40, heat & repeat and it'll go.

To make it turn by hand you will need a lot of WD40 and time, if you don't have one try to borrow a Stillson style pipe wrench and grab the rod by the small unthreaded zone, with that type of wrench the more you pull the handle the more its teeth tighten against whatever you are trying to turn...

To start off with, get a nice wire brush wheel, put it on a drill motor and clean all of the rust off of the exposed threads. If after cleaning the exposed threads, it still won't move, apply a little heat and oil to the jammed parts until it does move. Then, once your get things moving, clean off the parts that were covered. Then cover everything that moves (especially the threaded parts) with lithium grease.

Search for linear actuator blueprints. You'll find out that you already have it there, "just" motor is missing. Once you free up jammed mechanism by good advices you got here, try to find out what torque is needed to turn the shaft. Old car wipers motors are pretty strong. If high precision is needed than you must go with stepper motors.
