    Web Portal and Collectd/rrd graphs automated installation

    Planeplotter is still around, however I find extremely frustrating to use. It sorely needs refactoring to modernise the user interface. It has a lot of functionality that other software doesn't offer - for example obtaining locations using radar sweeps and they were the first to implement an...

    Web Portal and Collectd/rrd graphs automated installation

    Currently I'm feeding planefinder, flightaware, fr24, adsbexchange and will feed 360radar if they ever reply to my email about it.

    Web Portal and Collectd/rrd graphs automated installation

    Yes, I just reinstated my ADS-B receiver after it being off air for quite a while. I had quite a bit of software to update..

    Good grief that was 4 years ago. Where does time go?

    Plane Finder Client New Version! 3.4.25

    I installed it last night and it was working, but appears to have stopped at some point a few hours later. There was nothing untoward showing in the logs and the error log was empty. A few comments - The 3d polar view is very nice and should be quite useful for showing dead zones due to...

    ADF4351 signal generator

    The current outright world record for a circumnavigation is held by a sailing boat. 15 days faster than a nuclear submarine. :D

    Plane Finder Radar

    That's quite an improvement. What is the receiver based on? I assume that it has considerably better dynamic range than the dongles 8 bit ADC. Is it software based, or are you using an FPGA?

    Plane Finder Client New Version! 3.3.222

    I've been running the update for a few days now. All seems OK and no errors reported in the log.

    Web Portal and Collectd/rrd graphs automated installation

    Yes, it's possible to monitor mlat traffic levels using collectd. If you have dump1090-mutability version 1.15, and the the most up to date files from dump1090-tools then collectd will create an rrd for mlat. User jprochazka on the Flightaware forum has made an installation script that can be...

    ADS-B DIY Antenna

    N connectors are pretty robust. They also have built in weather sealing in the plug.

    ADS-B DIY Antenna

    I need to do some more testing, but the scanning program takes a while to do bigger sweeps. I'm pretty sure there is something not quite right with the connector though.

    ADS-B DIY Antenna

    I haven't put it in to the main set up, but I've been experimenting with a spare dongle. It seems that there is significant attenuation at 1090MHz as well, since the aircraft count drops quite a lot when the stub is attached to the T connector. The length of the stub is correct according to the...

    ADS-B DIY Antenna

    I decided to make a tuned stub filter to try and reduce the signal strength of the annoying cell towers at 950MHz. It seems I got my measurements OK, as there is a big reduction in signal strength at that frequency. Blue is without stub, green is with it. The only thing is that I'm a bit...

    ADS-B DIY Antenna

    dump978 only runs on Linux as far as I'm aware. It might be possible to compile it on windows, but I don't know how to go about doing that. The repo for it is here: https://github.com/mutability/dump978 OBJ (Oliver) is the chap who wrote the mutability fork of dump1090 among other things. He...

    ADS-B DIY Antenna

    dump1090 mutability is a fork of the previous dump1090 versions. It does the same job - decoding ADS-B transmissions, but has a few extra features. It can run the dongle at a higher sample rate, which improves decoding (with the downside of losing Mode A/C reception. Not a problem unless you...
