After my early tests with SvxLink-LCD, I realise that the Pi-Plate was not the only possible display unit in circulation, and I had both of these. Pi-Touch may still be available. Check the availability from thePiHut.com
As it turns out, the build structure was very similar to the LCD, but requiring a local webserver within the Virtual Environment created for it.
The full instructions for the system can be found here – https://github.com/f5vmr/svxlink-touch/#readme
