Today I added links to the (updated) documentation.
It documents the new proto-2 version schematics and pcb (with SAW filter). It also has the newest firmware version (V55) that communicates with the PC application, programmed in Tcl (latest version, 6, provided).
It has pcb Gerber files and assembly drawings. The new BOM includes placement coordinates for the components.
These docs should be enough to duplicate the project !
