That's a generalisation - that the RPI3 are unreliable. It'd be nice to
throw high-end hardware at everything, but if you had a very large
system to build - I don't think you would be doing that. And we do have
a very large system to build...
Lists aren't about one person building one machine, lists are about
system-builders assembling a nation - and that process being doable with
quality dividends, so it is easy for one person to announce costs being
minimal for one system, but if that single device were implemented
globally, that would be six or seven figures. That'd be nice for those
who supplied that device, but I don't think they'll get it.
I mean to say, app_rpt can, and should, be on every transmit and receive
interface on every mountaintop. Be honest - conversion of all systems
is our goal, not because we might, but because of the immense
flexibility it would forward, without really any effort at all. So how
to actually get that? Using a $300 box for every TX and RX? No, it's
not going to happen. Using a <$100 box with four TX and four RX
interfaces? Just maybe..

The Pi is already good to go, and some of the channel drivers will
already use the onboard I/O.
There just isn't a driver that does ALSA audio, DSP, generic GPIO, and
voting. If there was, we'd never be having this discussion ever again.
Also, it'd be dead trivial to write a config script to set the whole

All the really great ideas get implemented at some stage. The person
who WANTS to do it, notes it and puts it on the back burner - to be
implemented NEXT. All visionaries implement the BEST idea, not their
own idea. Discussions like this only pave the way, or is it 'a' way..
Or maybe, digital is better...
