WatchDuty seeking someone to help fill in an ADSB hole in Oregon. If you are here they want to send you a receiver you can plug into your Internet (not sure if there's good Internet up there, however). #oregon#adsb#wildfires#CraterLake
@ai6yr It'd be nice if someone was working on a federated protocol of sorts for the collected adsb data instead of the fractured collection that exists now.
On your history, I think you can enable something in dump1090 but it's use at your own risk sort of thing last time I looked into it. It could be that it's rpi sdcard destroying type of thing is all.
@AE4WX RTL-SDR usb stick and (ideally) a good antenna, outside. I like the RTLSDR dongles (about $35.00). There are cheaper versions from China, but about 1/2 the time you get a non-functional one, so I stopped buying those.
@AE4WX Lots of designs. Ground plane is easiest to build. I built a collinear (ie piece of wire with little turns in it) for my home station. You can buy a commercial 1090 antenna too. The receiver I have with the best reception is just a collapsible TV whip on a magnet mount... But it's in a high mountain location.
@AE4WX@ai6yr
I use an RTL-SDR dongle, a tuned co-linear antenna with a filter and a preamp at the mast head as high and clear as possible.
This gives about 350km range depending on terrain.
Leaving out the filter, the preamp and the co-linear gives about 100km range using a simple quarter wavelength antenna.
Dongles from Flightaware include the filter but I prefer to put the filter before the preamp. https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/
@AE4WX@ai6yr
Oh yeah, I run the decoder on a Raspberry Pi which produces a BEAST stream, and use some dreadful text based code I wrote on my work-station to decode that stream.
@zl2tod@AE4WX Dump1090's web interface is sufficient for most of us. VirtualRadar is nicer, but being a Windows app is unreliable as heck (and requires windows or MONO, and is still unreliable as heck under either).
@ai6yr@AE4WX
Yep, Dump1090 and it's successors are good for real-time. The bucket of spaghetti and slugs I use tells me which aircraft have been seen when I wasn't watching.
@zl2tod@AE4WX I'm sure there is something out there for this, but I really need a historical archiving tool that holds history for a day or a few days so I can play back or search for specific flights (without relying on a third party website).
@ai6yr@AE4WX
I archive the BEAST stream en masse and use scripts to pull out individual aircraft, which aircraft were seen on which day, which days specific aircraft were seen etc. Clumsy and slow but it works with a minimum of coding.
