What streaming platform is easy to use?
I use https://www.internet-radio.com/ for my station. They have a PAYG package and then various pay monthly packages. I’ve never had a problem with them.
You’ll also need to think about playout software and the studio. Will it be live broadcast or music only or voice tracked?
I had a look at https://radio.co recently and it seems to have a really clean and easy to use interface. That may be another platform worth considering.
