There are a lot of us out here that prefer to run hardened server-grade hardware at remote tower sites rather than Pi's or other small SBC's. --- Jeff
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..
I suggest finding a way to replace the I/O lines with something else because ANY dsp should work fine for the audio. I think the PI itself has them. Just have to write the code to replace it OR use "ON-EVENT" programming to read/write to them to follow ptt/cos.
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 thing up.
drivers? hardware? integration with existing codebase? takes time and (unpaid) effort. -- Bryan
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... S
