Following on from discussions at the 2019 Martlesham and Crawley Microwave roundtables about the need for an SDR based Microwave transceiver, Noel G8GTZ has wrote a project proposal which set out the idea of a phased development based on the Rpi to provide an all mode transceiver for microwave bands up to 3.4Ghz and possibly 5.7Ghz, using the Pluto SDR hardware.
Colin G4EML volunteered to be the main contact point for the project and Heather M0HMO has offered to contribute to the project which will be hosted on GitHub
We are looking for others to contribute towards the code or publish designs in ScatterPoint for the additional system components such as Pas, LNAs and higher band transverters.
The original project proposal is available for download here: File:The Hayling project version 1.pdf
Early Prototype Nov 2019
Colin, G4EML demonstrated an early prototype in early November 2019 running on an RPi4 with USB audio dongle and a Pluto SDR enabling NB operation all bands from 70MHz to 5.6Ghz!
The protype was running a touchscreen gui written in c controlling gnu radio.
