QO-100 Transceiver full SDR

F1ATB · Jun 23rd 2020

If you are interested by a transceiver based on SDR and remotely controlable from anywhere via your local network, I have detailed the solution I developped and used daily. It's based on 2 HackRF One SDR and 2 Orange PI nano computers. The signal processing is done using the graphical tool gnuradio-companion and detailed here:

The web interface "Remote SDR" will follow.

Your remarks are welcome

As long as it stays "local"

Interesting. I am not sure what an Orange PI is but that's a useful tutorial on how to use gnuradio.

There is also the option of using an Adlam-Pluto and an Ethernet adaptor. Not sure using a HackRF is a good idea for new designs in 2020, plus you only need one Pluto as it does Duplex and it works out quite a bit cheaper.

Colin G4EML has developed some software, also Gnuradio based, for the PI https://forum.batc.org.uk/viewtopic.php?f=129&t=6602 that makes a stand alone transceiver, not just for QO-100 but all bands from 4m to 6cm. It's not duplex yet, but can be.

On a PC Simon's excellent SDRConsole can drive the pluto and several other network based SDRs.

Now the complete description of the remote SSB transceiver with RTL-SDR or Hack RF is available. It adresses the signal processing with GNU Radio on an Orange PI, the post processing in Javascript and the web interface. The sourge is available also on GitHub.
