I have no idea how many KIWISDRs (ver. 2016 by jks) have been released since 2016.

The purpose of this post is to call a collection from all over the world.

    The picture includes a linear power supply, a pre-BPF, kiwisdR+Aluminum enclosure, and wifi hub. The fan was intendedly moved to the outside to reduce vibration.

  • jimlill.com:8073 and jimlill.com:8075 are 2 of the 4 kiwisdr there. The other 2 are dedicated to wspr. I am currently suffering from some local noise that I haven't had time to chase.

    very good idea.

    Récepteur KiwiSDR de Trémolat, AutreRadioAutreCulture (Périgord, Dordogne, France).


    Antenna mini-whip Dual Fet, stainless steel antenna mast 50 mm in diameter at 3.5 m in height, 50 meters of silver RG 58 coaxial cable.

    Antenna filter.

    52 meters from the antenna, the receiver box is placed in a technical bay (19", 27U); Schneider case in steel, not aluminum, it's important. TP Link ethernet switch (there are several other switches before reaching the Internet router, the network is large).

    Interior of the armored box. Bel 784-HAA 512-AG linear power supply, 5 Volts and 12-15 Volts. Mains filter (RFI TE Connectivity 3A-250V). 12V injector (double coil) for the active antenna. The ventilation grilles are behind the power supply (cannot be seen in the photo).

    Shielded, grounded cover.

    Behind the rack, the surge protector and the arrival of the earth connections at a central point.


    • the mains power supply (230V + or - 1%) is produced by two OnLine Socamont inverters (2 x 6KW) and backed up by 2KWh of batteries. The wiring of the mains installation is carried out in "IT", without neutral. Several large sector filters are inserted (Schaffner FN2410H series).
    • During the day, the system runs on photovoltaic energy.
    • the night sky of Trémolat

    Best regard, Philippe

    My provisional (solar-powered) experimental setup on a wooden board:


    1. Kiwi in its original metal/plastic frame and with its unused GPIO lines led out (over series resistors) to a D-Sub socket.
    2. Homebrew 6-way antenna switch, controlled by the GPIO lines, and with the general 12V DC power supply input for the whole assembly.
    3. Shielded switching regulator 12V --> 5V with additional builtin chokes and pass-thru-capacitors for lowest possible interferences (kiwi sometimes shows SNR above 40 dB).
    4. Heavily modified ESP8266 Relay module, flashed with Tasmota firmware. Allows me to remotely turn the kiwi on; it can also measure temperature (DS18x20 Sensor) and the supply voltage via ESP's ADC input. With a simple self-written daemon interacting with the relay module, the kiwi can auto-turnoff itself if unused for more than, say, 4 hours. (I added a hardware turn-off-delay to the relay module, so the kiwi has enough time to properly shutdown after sending the "OFF"-command to the relay board.)

    As said, this was intended as a provisional test setup only, but is now already running for many years. Nothing is as durable as a temporary solution. ;-)

    No URL here, as this kiwi is still not publicly available.
