Raspberry Pi type B + DVB-T Dongle to feed FR24

[andyk1]

WHY... I wanted to Move FR24 to a much less power consuming machine... 290-350 watts at idle. I do turn off the two outer monitors when not needed but still at approx. 200 watts.

Ok anyway i solved my problem. sometimes airplanes occour with my radar I make some pictures for you

used the Little antenna directly from the dongle

Well I have a home Built from the ground up AMD 8350 cpu, 32 gigs mem, 850 watt power supply, HIS 7970 vid card with 3 gigs mem Pushing 3 (three) 24" monitors , 230 gig SSD for C:\ Drive, About 7 Tera bites of useless storage space on 3 drives D:\, E:\, and F:\ Drives. Only two Blue ray and DVD burners hehehe. Oh and water cooled with 340 mm radiator and a 240 mm radiator. Keeps my room toastie in the winter. Is that enough Power...

I did try the Hyper-V on an older generation 2 processor machine with quad core Xeons - a machine that would have been very happy running vSphere, but with Hyper-V performance was dire. A modern i7 based machine ran it well. It seems that SLAT is more important than power. Sorry I don't know the AMD processor numbers, seems like a great setup - very much an overkill for flight tracking, so agreed about why to run on a Pi / BBB.

Great cover from the simple antenna, Have a look at the dipole or franklin dipole (made from co-axial cable) here http://forum.flightradar24.com/threa...antenna/page12

Mount it as high as possible (top of a bamboo cane fixed to edge of the roof) ... should make a huge difference.

Yep I hear ya. I am going to install a Linux version soon But haven't decided which yet. Am working on my antenna issue. I need to build a new one outside of PVC pipe and I didcovered that the cheap Antenna amplifier actually did help. The cheap one I mentioned way back. It was made for television reception up to 900mhz but I read when I started they will work and damn if it doesn't. It's one with a pre amp at the upper mast head and a power injection (12 volt) at the end of the coax just before the sdr dongle. Soooo that tells me it's an important ingredient to this mess I am building.

If you could move that setup or just an antenna to say house top level you would get more than just a few sometimes I would be willing to bet...

You have both Ethernet and wifi plugged in at the same time?

Am really confused on which antenna to try. Did you build that antenna Peterhr on the antenna tread?

The last one you and Herman where talking to abcd I think. The franklin Co I believe?

[peterhr]

I built a co-linear out of coaxial cable maybe 5' long and stuffed it into a 3/4" / 21.5mm PVC water tank overflow pipe (which I then stuffed into a 1" speedfit plastic plumbing pipe 'cause it looked frail in the wind.

I'm thinking about a Franklin - but what to make it on so it's not attached to something that blocks signal

Ya that's my problem. PVC is out for me as I saw the test results. Fiberglass is better but still a db loss. Thinking of some way to bend copper or brass rods or something

support the franklin on the bit's that stick out ... they're not doing anything in the way of receiving anyway.

btw. Maybe you could apply for an f- receiver they're looking for Woodward, OK, Lawton, OK & Tulsa, OK and you're in the middle.

There is already one here (F-KPWA1) and yes I know there looking for more but just NOT where I am. I don't think it would be a benefit to them to have two Boxes 15 miles apart or so I'm guessing.

Antenna is kicking my butt. I think in the long run it would be cheaper and wiser to get one already made like the one at the rtl1090 store I can't remember the name of. Just need the one with 30 meters of cable. I can't tell if that one already has the pre-amp at the mast head or if you can add one.

I keep being driven back to this one and I think for the money and performance shown it's the best bet. http://h2204566.stratoserver.net/Sma...s-b-usb-dongle

Haven't seen much talk about it but the stats seem good to me. Not sure if this is the one ABCD? on the other tread was talking about as his link was dead on my end and I couldn't see what he was talking about. Antenna's are not my best either but I do understand how they work and the principle behind length and frequency's. The other thing to consider is a filter to is a good quality filter to filter out in coming freq's such as FM which is here anyway very strong. They do make 1090 filters I saw but don't have a link. The cost was approx. $39 US dollars but can't find it again. Have to search YouTube again for it. There are so many things now to concider getting optimum performance out of this thing it's funny. a good ANTENNA being the main factor. From there everything else seems simpler to figure out. A good quality pre-amp at the mast head is also a must for long range reception of the very distant ads-b signals.

Any one can get the cheap SDR dongles to work. Depending where your antenna is located depends on your performance. To get out and "touch" the longer, higher, further signals takes thought, work and dedication for sure. Lots of sleepless nights thinking about making it better. Well back to tinkering with this thing.

So the bit's that stick out, are those facing down? I can't find a picture of one in use to see how it's mounted. I can't even tell if it's vertical or horizontal mount hehehe

On the 'Best Antenna' page http://forum.flightradar24.com/threa...antenna/page12 the diagrams show a 6.8cm 'loop' between the dipole sections ... use those (multiple) for support.

I'd love to try it, but I can't see when I'll get time to do mast stuff in daylight, especially since the evenings are now closing in and weekends are busy. (maybe I should put a pully on the top of the mast so I can quickly pull temporary setups up without having lots of disassembly, re-assembly.

Hehehe Same here. Days are getting shorter and I need a way to get to the top of the mast easier. Not an easy thing raising and lowering a 45 foot (15 meter) mast over and over. I'm stumped which way the two ends face. Horizontal or vertical like yours on bamboo pole.
