SAM Broadcaster? Forget it.
We used SAM Broadcaster - briefly. We found that it was rather unstable on Windoze 7 (though it wasn't bad on XP), and would spontaneously crash, often requiring a complete reboot. When the Win 10 nagware started, it became completely unusable!
We made the biggest change possible - we moved to Ubuntu and "Rivendell" for our 24/7 streaming service. It took a little time to learn our way around the new OS and software, and to integrate it with our record library (which has always used Ubuntu).
We stream using Icecast, and the results are superb. Quality is high, stability is perfect and the "live" option works flawlessly for programmes with live presenters.
There was a fairly steep learning curve, and there were a few configuration niggles that were sorted out with the help of the very active Users' Group. We now use entirely FOSS software and operating systems throughout our studio centre - saving us a fortune in licensing and support costs!
