Remote SDR – Examples of realization

by · Published · Updated

Many OM around the world have embarked on the realization of Remote SDR. Below are some examples.

Listening EME by BG0DXC / BG0AUB

Listening on 23cm. The low bandwidth required to transport signals over the network is appreciated with this remote station. Remote SDR is interfaced with WSJT-X which drives Doppler drift.

Realization of HA4BM from Hungary

Nice construction with an Orange Pi Zero 2 and an Adalm Pluto

Béla, HA4BM himself designed a box made with a 3D printer. The sources to achieve it are available here:

RPI4 ° POE + Adalm-Pluto

Another version with Raspberry Pi 4, a POE Hat and the Adalm-Pluto. The 3D box file is available here:  https://www.thingiverse.com/thing:4940238

Realization of HB9DUG

Raspberry Pi4 and Adalm-Pluto

Michel, HB9DUG has successfully ported a Raspberry 4 with 4GB of memory, Remote SDR. It is driving an Adalm-Pluto.

Since a version 2.4 exists and runs on a Raspberry Pi 4B with only 2GB of Ram memory. The procedure for installing an image is here: https://f1atb.fr/remote-sdr-v2-raspberry-4b-image-installation/

The average CPU load rate is 33%, which is good.

Htop gives a load of 1.29 splitted on 4 cores which correspond roughly to 33%.

Realization of F1ATB

The first realization of Remote SDR which allowed me to establish my first QSOs via the QO-100 satellite in May 2020.

F1ATB QO-100 setup – Raspberry 4B – 2 HackRF One

It is an old PC box which serves as a 5V and 12v box and power supply for the whole. The processing processor is now, september 2021, Raspberry 4B – 2GB.

Realization of F1APY/F6KAT

Superb QO-100 transceiver with an RTL-SDR key, a HackRF One and 2 Orange Pi One Plus.

PA Nokia UMTS and Remote SDR

Test conducted by EA3IGB Pau.

Give me pictures of your setups to publish them here.

Realization of G1BVI

TX with HackRF and RX with RTL-SDR

    Hi DR OM André,
    Congrats for this one excellent work for ham radio community.
    I would like ask you if is possible ADD TO SUPPORT to image for Airspy receivers like Airspy Discovery, R2 and MINI.
    Also Anthony F4GOH described how simply configure Remote SDR V2 on his website.
    Amazing support!!!

      Thank you for your positives remarks. In the coming months, I will continue with other SDRs as far as I can find the drivers to adapt to Remote SDR.
