I like this project as it finally provides a way to retrofit an existing analog rig to do multiple digital modes. It and its user base should show potential manufactures what the community wants.
Sadly what seems to get the most interest is the DroidStar app. But that is okay too, as I see that helping fuel attention to the underlying software vocoder performance issues. I am hoping sooner or later someone with the software skills will step forward.
And for the app, I do think this makes more sense than having to buy multiple digital radios and a "hotspot", to effectively talk (maybe 10 feet over RF) over the internet on these modes.
