In this video I'm trying (again!) to get some L-band satellite signals with a re-purposed wireless networking dish. I've got a helical antenna feed made of scrap wire and a cookie can, a software defined radio, and a Nooelec SAWbird+GOES filter to boost the L-band signals.
I initially tried using my MobileDemand tablet / "mini cyberdeck", but it turned out to be too slow and laggy to record High Rate Picture Transmission (HRPT) data streams. A regular modern-ish laptop worked much better for that.
I'm using SDR++ to record the signals (www.sdrpp.org/)
I'm using SatDump to decode the data into imagery (www.satdump.org/)
Here are some resources I've found helpful for doing this:
sgcderek.githu...

The hardware I'm using can be found here:

The sun is a valid and very interesting target for radio astronomy. A solar tracking mount would just work, no need for modification. The sun is also useful for finding your dish's focal point. Put strips of reflective aluminum tape across the dish, point it at the sun, and find the brightest focal point with your hand. The phase center (what you want to put at the focal point) of your helical is probably ~0.2 wavelengths away from the ground plane.

Oh come on, everyone knows the sun is just an elaborate hoax put on by the government... /s And no, the focal length of a parabola is not dependent on the wavelength. What is dependent is the gain - the higher the frequency, the larger the dish looks electrically (size of the dish considered in wavelengths of the signal)

You probably want fewer turns on that helix. The gain of the feed needs to be "matched" to the F/D ratio of the dish. For a shallower dish (where the feed point is further from the dish) you want higher gain, and for a deeper dish, you want less gain (larger opening angle of the feed pattern). For a prime focus dish like you have, the formula to find the focal point is D*D / 16d. Where 'D' is the dish diameter, and 'd' is the depth. Just looking at the dish, I'd lop off a couple of turns on that helix. The "hazard" is that you under-illuminate the dish, and thus you're using much less of its reflector surface. So your nice 0.85m dish is actually operating more like a 0.5m dish, because you're only "illuminating" part of it.

@patchvonbraun
@patchvonbraun 10 ай бұрын
For a dish with a "usual" F/D ratio of 0.35 to 0.42, your feed needs to have a gain between about 8dB and perhaps 10dB at most. There are online helical antenna calculators that show that 3 turns gives you about 9.5dB and about 60deg beam width.
@eswnl1
@eswnl1 10 ай бұрын
Does it go both ways? If you over illuminate the dish, you pick up noise from the periphery of the dish and raise the noise floor. In that case you need to determine the precise beamwidth of your feed.
@patchvonbraun
@patchvonbraun 10 ай бұрын
You don't have to be *that* precise, in practice. Rules-of-thumb can get you fairly far. In radio astronomy, the tendency is to *slightly* under-illuminate the dish to reduce, as you point out, spillover and ground-noise pickup. In other applications, you might want to maximize the forward gain, even if it means a bit of ground-noise.

There's a trick in tying many-lead round-braids (turks head) that I think might help you here. First you get a sheet of paper as wide as the circumference of your tube, and as long as you want, set it out in front of you portrait style. Draw horizontal lines marking out the wavelength, and diagonal lines starting at one wavelength end and going to the opposite end of the next wavelength. Then draw 1 to 4~ vertical lines as appropriate for the size of tube. This is your drill guide, wrap it around the tube so the wavelength lines touch themselves and form rings. Drill holes anywhere the helix crosses a "vertical" (now lengthwise) line, and anywhere the helix crosses a wavelength line. Put firm fitting but removable nails in the holes and wrap against the pins. Simplification: Do most of that but instead of drilling holes, punch holes in the sheet and mark through them onto the tube. tip: Use tape to hold down the wire as you go. If you're willing, you could even do the markings method, and tape the wire down semi-permanently, with the tube becoming part of the antenna. Maybe add crosshairs to the tube and pretend you've made a radio-spyglass In round-braids, you lay out lines for every pass of the cord with phase offset wavelength lines, then notate all the overs and unders. The nails hold the cord where it will need to be for future passes, it gets really tough to keep everything arranged physically and mentally without an aid like this. If there's a vector graphics suite you're comfortable with, you should be able to make this pattern once and then scale it to whatever circumference and wavelength is appropriate.

Or even a used Microsoft Surface tablet (which is what I use with my SDR dongle) would work great. Also, have you considered using an old school antenna rotor to move the dish to track the satellites? Admittedly, I'm not sure how that would work, but I know they can turn a full 360 degrees.

How are you measuring azimuth? If you're using a compass, are you correcting for the magnetic declination at your location? The best way to "blind" point an antenna is set the elevation to the correct angle (measure it with your phone, or even a protractor with a string with a weight hanging from the protractor), and then sweep the azimuth to find the signal.

The intel Atom processors are largely just like any other x86 processor, just made for very low power on the order of 1-10 watts depending on model. I think the problem you're having has more to do with the early Atom's being 32 bit only, and most of the world has largely abandoned 32 bit over the last 10 years. The later 64 bit atoms are great, and I still have two of them that'll easily run modern Linux distributions. Too bad yours is 32 bit only. It's certainly possible that you might be able to re-compile your software as a 32 bit app.

I'm betting the Atom in that tablet can't keep up recording the samples to disk in real-time, and that's why your recordings failed. It might not even be able to read from the SDR in real time -- you can verify that by running "rtl_test" at a command line. Also, some types of old flash storage can have really low write speeds -- possibly lower than the ~2 MB/s you're reading from the SDR. A USB flash drive might be faster than the internal flash, but the extra USB bandwidth might make the SDR sad during writes.

If you're just running a SDR would you be able to get away with something like a Pi Zero W 2? If you need x86 you can do one of the Lenovo 1 liter PCs off ebay. Lenovo has their slim tip to USB C adapter for those and you'd be able to run it off a portable battery. I don't think any of mine pull over 30 watts in average use and idle around 10 watts. I use those instead of Pis now and it's really easy to just SSH/remote desktop into them with a phone or tablet for control.

There isn't a lot of difference - they're both 32 bit x86 cores - most of the differences are just marketing, and how much cache they have, and what other hardware has been disabled (probably because it didn't pass self test). The only requirement is you need a distro that cross-compiles all the packages to i386 (32-bit) yet, and like you mentioned, debian is one such distro that stuff has the full package suite available for i386. But at the same time, just throw that piece of crap away, and pick up a used Thinkpad for $200 - problem solved, and it's better in every way.

The power demand of SDR USB dongles can be an issue for laptops. My RTL SDR dongle for example draws about 160 milliamperes and was shortening the duration of operating sessions with my laptop. To solve this, I made a USB function-splitter Y adapter cable for my SDR dongle. The SDR data goes from the dongle through the adapter cable to the laptop per normal but all power for the SDR dongle is sourced from the other leg of the Y adapter which is plugged into a standard off-the-shelf USB power bank. For greater clarity, the leg of the adapter cable into which the SDR dongle is plugged has all four USB wires (data + & -, and DC power + & -), the leg that is plugged into the laptop has both USB data wires but no connection to the USB power wires, and the leg that is plugged into the power bank has both USB power wires but no connection to the data wires. The adapter cable works perfectly for me. One must of course take care to ensure correct polarity of connections when making the adapter cable.

Would an alt-az mount for astronomy purposes be useful for tracking? Some can be controlled via Stellarium. Not sure how the slew rates of such a mount would match that of satellite passes however. Good luck in your projects.

Satellite hams often use 2 rotors and a program called ham radio deluxe - try looking at that. Seems ham radio operators have solved some of those problems for you. Now, I have a question for you. I see you have lots of dishes… do you happen to have a 1.2 meter offset dish laying around? I’m needing one… are you near tennessee? I’ve got cash lol - I can buy one but shipping has now gone above the cost of the dish

I haven't had the $ for two rotors, all my stuff is dumpster dived or traded! Also no offset dishes at the moment, I think I even gave my DirecTV dish to a scrapper since it wasn't useful for anything. Sorry!

If you were to hang the dish above your head with a rope you would not have to hold it and it would be easier to aim.

Hey, almost forgot about it! I'm interested but don't know how I'd get it, where I'd put it, or what I'd do with it! I guess don't hold onto it just for me, if you can find someone else to take it. I don't get up your way very often and when I do it's usually in a carpool full of people and camping gear with no room for big treasures 😢

photography umbrellas aren't really parabolic - they're just parabolic-ish. They're just reflecting light in generally the right direction, not a super precise reflector. For RF, the surface accuracy of the reflector should be within 1/10 of a wavelength, so at 1.7GHZ, the parabola needs to be accurate to within ~18mm at all positions on the reflector. I very much doubt an umbrella is going to meet the spec

Do you have a video on designing antennas? If not i would love to see one! I am currently making a project using LoRa and i want to make a semidirectional antenna thats stationary and another onmidirectional antenna thats constantly moving but i cant find any good sources on how antennas are designed at a "for dummies" level.
@saveitforparts
@saveitforparts 10 ай бұрын
I'm not really an antenna expert, I just crib other people's designs online and experiment to find what works. There are probably some much better theory resources out there! Heck, the little NanoVNA thing I've got will apparently do a lot more antenna analysis that I know how to do.
