The Easy-digi circuit is a common design. Nothing more than a few transformers etc. Maybe try adding Kevin Loughlin's DuinoVOX design to the Radioino controller via some sort of menu function to enact the VOX part? Good isolation is a must IMHO.
There are many speech processor designs around for the FT-817. Many of them live in the mic cable as an addition to the cable rather than an upgrade inside the mic or rig itself such as this one (prolly based on Jeff's design?) http://www.box73.com/product/4
