    [Receiver] Not a beauty, but (almost) a BEAST!

    This is my quick and dirty shoebox feeder, made out of a (horribly inexpensive ) recycled fruit crate:

    - Raspi B+
    - Powered USB - Hub
    - WiFi connection
    - 5V supply with ferrite core filter
    - test antenna on the top (antenna that was delivered with the stick, shortened to 6,5cm)
    - productive antenna under the roof
    - Aircraft noise feed to
    Code:
    www.DFLD.de

    Software

    On Raspi under the roof:
    FR24 feeder
    DFLD feeder
    XRDP remote access

    On my Windows Workstation:
    Remote Desktop to the Raspi
    Dump1090
    VirtualRadar
    DFLD Historical Noise record
    DFLD Real-time Noise radar

    Great, congratulations!
    It does not matter how it looks, as long as it performs good. Any way it is good looking as well.

    - test antenna on the top (antenna that was delivered with the stick, shortened to 6,5cm)
    Is 6,5cm length of removable part?

    That is a mighty neat build! Care to elaborate what is in the box, besides the FR24 receiver?

    Did I understand it right, that this is a box that you intend to recycle to become a FR receiver?

    It is up and running as F-KSAT2, not yet mounted at it's planned location, which will be about 6 miles North and 55' high. Right now sitting in a patio chair with the antenna propped up, testing the box functionality and tweaking the remote controls.

    Polycarbonate enclosure
    Solid state 150 BTU cold plate, coupled to a custom heatsink and fan inside the box.
    LTE modem
    web controlled temperature and power relay modules
    internal and external temperature probes
    4 port ethernet hub
    110vac>48vdc power supply
    48>24vdc converter (for modem, relay module and hub)
    24>5vdc converter (for FR24 receiver and temp module)
    LTE/GPS combo antenna (modem LTE and FR24 GPS)

    Lots of room left in the box for other receivers/gear.

    That's excess cable from the LTE/GPS antenna. It's a mobile antenna. I may chop it off and put on new SMA connectors, but not likely. Good SMA crimp connectors cost a few bucks each and it works fine like it is.

    The FR24 antenna port is fed from a SMA bulkhead connector on the bottom of the box where all the other connections come in.
