ADSB Exchange Deluxe Dual SDR Feeder Kit - Aircraft Tracking

[@jaym1301]

For those complaining about the price, after buying a Pi 4 at current prices, a power supply, an industrial-quality SanDisk micro SD card, two good-quality SDR donges not the cheap TVRO ones, LNAs, a 1090 filter, coax , antenna(s) and a Pi case with a cooling solution, and factor in the value of your time assembling it all it will have cost you at least US$ 350.

[@TechMindsOfficial]

Spot on!

[@justplanefred]

It comes with the Antennas that that box comes with... I think you'd be about half that and about a half hour or so to set the whole thing up. Unless your adding a real antenna and coax.

[@jasonprivately1764]

Don't need a pi, nor the piggyback link to a corporation I allow to capture my data, which in turn feeds it back to me. Though for those that are using this device you can send all data To a program called " virtual radar server" and keep your data to yourself. This device is similar in methodology to AirNav's radarbox

[@K4HLW]

I noticed you mentioned the lack of a Bias Tee, that is because the SDR has a LNA built into it already, if your using an external one also make sure you lower the gain a lot, or set "adjust gain every 24 hours" to yes, or nearby aircraft will overload the receiver.

[@TechMindsOfficial]

Good point, but also depends on the type of coax used. At just over 1 ghz there will be loss.

[@jaym1301]

@@TechMindsOfficial The amount of attenuation depends of course on the type of coax used and its length.While there will always be feedline loss, the attenuation of 10 meters of LMR400 or equivalent is less than 2dB while 3 meters it's only half a dB. As Brian Cook mentioned, given that the ADSBExchange SDR dongle has its own internal LNA you would definitely want to reduce the dongle's gain if also using an external LNA along with a bias-T injector to power it. Otherwise you'll be losing aircraft from the tar1090 map due to strong-signal distortion and SDR front-end overload, especially those aircraft that are near your location.

[@K4HLW]

@@JxH think of it this way, chances are at least 25 other receivers are seeing that 747 flying at FL40 that is 100km away. But your receiver may be the only one picking up that piper at 200ft on final approach, or yes, that police helicopter over your house. Range and number of planes/packets received are easy metrics to build leaderboards over, but the techniques used to rise on those boards can actually lessen the value of your feeder to the system as a whole. So if you ask the people running the sites they will tell you unless the rare chance your the only feeder in some very large geographical area then they would absolutely prefer you turn the gain down and get that low police helicopter, or the last few data packets from that plane that just crashed nearby. Those feeders set up this way are much more liking to provide missing data.

I run a pi with a PoE hat which is in a waterproof box attached to the mast with a very short antenna lead

[@yaroslavartyukh964]

The only one good decision

[@TechUniversity1]

Anyone have any videos of what the inside of this thing looks like?

[@acedriver5380]

I am interested in buying an ADS-B reciver to spot Civil and Military Aircrafts, the thing is that I do not know on what or how Mlat works. and most planes I see on RTL1090 is only ADS-B converge. Is there a way to see MLAT somehow ? Thank you

[@Kpaojd]

How do I measure the coax length required?

[@perkunast9680]

Why is it not powered by POE?. Why run a second cable

[@ReefMimic]

Did I read somewhere you want the bias tee as close to the antenna as possible?

[@jaym1301]

That depends on how long your coax is.As a rule of thumb for any coax run of less than 10 meters, having the LNA built into the 1090 SDR dongle is fine.At 10 meters or longer, you should be thinking of using an SDR dongle with bias-T an a filtered LNA at the antenna for better SNR and linearity.

[@SimoneSessler]

Can I get access to the raw data that my unit collects if I want to build my own application?

[@TechMindsOfficial]

port 30003 I think is exposed.

[@texhow1]

Is this unit still available & what price please.

[@ME10920]

Needs to be half the price

[@timlc]

Yes, agree. Just spent a while locating it on their store, and was quite frankly shocked at the price. Going to stick with the SDR 1090 interface I think

[@chartphred1]

Agree. Way outa my price league

[@JS-iu3hd]

Half price would be less than the cost of the hardware. Doing the math this is likely marked up roughly $50 USD from cost. They are probably losing money on it if you count assembly time, shipping, selling fees.

[@jaym1301]

​@@timlc I've never heard of anything called SDR 1090.Do you have more information about it?

[@timlc]

@@jaym1301 sorry, bad text on my part. I meant the 1090 plugin (can’t remember the exact name of it) on my sdrplay SDR

Pity the second SDR can't be configured for voice.

Well yeah, but I meant integrated into ADSB Exchange itself without having ot molest the install.

[@wiedehopf9068]

You can run a normal Raspbian if you wish.

One day toy, if you are no James Bond to be ready to search Dr. Evil by his plane 😹

[@justplanefred]

Nice video on this product. I think they could sell it a bit cheaper not a lot because they still need to put food on the table and all plus they get the parts for this much cheaper I'd expect since I used the prices they sell the parts for as I have no idea what their mark up is. Maybe if it included that 5.5dbi antenna it would be more reasonable. Probably could even put a short rf cable that was a little higher than desired loss.

[@01mememememe]

Hope you was gifted the ADSB box, now the company has been bought you may wish to feed no longer

[@42markk42]

Way too expensive for what it is - Matt , I'd have liked if you had disassembled it to see what was inside and how it was built - Maybe another video?

[@TechMindsOfficial]

I’ll take a photo of the insides and post it on my Twitter in the next couple of days :)

[@wiedehopf9068]

The only fancy thing is the aluminium case and some heatsinking. It's mean for people who either need the case for some reason or don't want to deal with serializing the SDRs for 1090 / 978. Ready to go is something some people will pay a pretty penny for. The adsbexchange sd-card image is openly available if you want to use it for an RPi with an SDR.

[@justplanefred]

You could also go to the website... they sell all the pieces but the case and the Raspberry Pi that's in it. It's just a nice little package and all set up other than a few minor details which are mostly location based and that was shown in the video

What’s wrong with Sharing?

[@jasonprivately1764]

@@TechMindsOfficial , in actuality the concept of purchasing a device at a high cost for immediate and real time access, only to have to send it over an open channel to a site then having to wait for the server to send back the packets I just sent. While stuffing their database full of a my data and returning the local data I sent them. As my site is fixed and I have no need to collect data from other areas. By accessing my own data, the devices I use maintain security and have no access to the internet. No ports are open unless I declare them. The traffic is maintained and logged in house. While maintaining the highest granularity of data, I can record with limited latency, thereby allowing my programs and subsequent formulas to extract data as I require, as soon as available. Personally I otherwise have no opinion on sharing. It follows a case by case nature. No disrespect intended or implied.

[@TechMindsOfficial]

No problem, was just curious. Of course you can expose ports and use virtual radar server. But nothing that a cheap SDR dongle cannot so connected to a computer. I guess this device is for those that don’t or can’t setup their own adsb system. Cheers

[@jasonprivately1764]

@@TechMindsOfficial if the operational parameters were custom matted to specific to custom software/firmware i would look into a debug, however with the generic software made available and the plethora of available public domain software available plus the community at large, the thought of single use feature sets without having nothing more than simple practicality is falling away. Personally, if I were to go at this from a newbie start again. I would use that price point for a hack5 or other tighter tolerance unit. Or perhaps several flight-aware mini devices for adsb, mlat and voice each fed through a mixer to both feed a meter or virtual network analyzer

[@JuanSanchez-ik7wx]

$349 seems a bit excessive for the parts in this kit. Especially if you consider that our feeds will be fed to them so that they can charge viewers for using the website. Great business model though......charging customers to build a product that you can then turn around and sell. Something doesnt fell right about this.
