You're welcome, Chance. Since I only tested this on one system and then burned the image, please let me know of any issues/errors you encounter.

Remember that you'll need to configure Darkice and figure out what streamer you're going to feed. I'm using Icecast running on a small Atom processor box to feed my home network.

At present, I'm still using the GUI but it would make sense for a version intended just to stream, to use the CLI only and save a couple of GB of size. That's still on the list.

Hey John,

Thanks a million! This was on my weekend list of things to do and I was just about to dive into to figure this all out. You just saved me a whole Sunday afternoon. I'm downloading the image now!

I had the very busy local feed (24 channels) running here for a couple of months and it seemed perfectly happy. So I think the system may be more stable than one might suspect.

I may go to Broadcastify, but they don't want you to stream TAC talkgroups, and I'd like to include those (quiet as they are) for the couple of local departments I listen to. So for now, anyway, I'm just streaming locally with Icecast.

(Does the Broadcastify DarkIce install as a Debian package, or does it do an out-of-dpkg install? I wanted to stay with .debs wherever possible.)

Hey John,

Everything worked perfectly. Only one change, I installed the DarkIce build from Broadcastify which included the MP3 encoder.

I'm feeding Sachse, TX. I use to carry a neighboring city with more activity, but since they went encrypted, it is just Sachse now.  I only mention in case you tune there, it is quiet 97% of the time.

I'll probably switch back to my other PI with a scanner while away from home, until I see that this runs stable for a while.  I'm betting I'll need something to restart RX.PY every so often....   But so far so good.  And no nasty background noise of the Whistler scanner headphone jack!

Thanks again.

Occasional stalling seems to have been an ongoing problem for me with the RPI3. Most of the time it'll run for day or weeks, then out of the blue the audio ceases to be sent to broadcastify. If I pull up the terminal screen the tsbk counter is running and the darkice process is present, but silence... Curiously the same symptoms have never manifested themselves on my other (main) stream hosted on an intel powered laptop.

Very soon I'm going to be moving away from using the PI3 as a host so hopefully reliability will improve. I obtained an Intel NUC7I5 that is going to run both feeds in parallel with the new web-based terminal as the front end. It cost 20x more than the PI3, but if it increases reliability and doesn't need so much babysitting it'll have been worth it.

I have been jumping all over the place trying to find a solid solution. I haven't had a decent opportunity to do a deep dive so basically like spaghetti, just throwing it to the wall until it sticks.

1. Ubuntu VM on Windows Host. I7 worked nice for learning and watching graphs, but did not want to tie up main machine to broadcast. 2. PI3, before I knew about Max and Botboad branches. Just can't tune quick enough. Misses short transmissions. 3. Dedicated 5th Gen I5 Desktop with Ubuntu host install, no VM. Tunes much faster, rarely misses. Audio always ends up crashing at seem point each day.. 4. Pi3 with John's image. Much improved. Idiot proof. But still late entry into many conversations. Tried cheap RTL and NoElec. 5. Just arrived, got the PI 3B+. Slightly faster CPU, better heat-sink. Going to try and overclock this evening.

I'll probably circle back to number 3 and turn on verbose and start digging. Eventually want two feeds which desktop can handle.

For what is worth, I have been having very good luck using the Pine Rock64 SBC as a replacement for the Raspberry Pi-3B. I can tell you that it runs circles around the Pi and moreover it can be outfitted very inexpensively with eMMC very inexpensively that make the Rock64 run even faster. I can’t testify as to how well it will simultaneously support streaming as I have yet to configure it to do so.

The Ayufan OS’s have been improving in reliability but at present I have been having very good stability with the DietPi Linux image running OP25 with not freeze ups at all running the http console and switching among plots.
