Internet radio, a simple computer with a microphone can do it. It's best to get a better sound card, condenser microphone, monitor headphones and professional mixer, which mainly depends on what you do, what you want to do and what effect you achieve.

Now there are also mobile phones, such as Momo. If you want to get it right, you can buy an external sound card for your mobile phone, and some directly bring applause and laughter.

If you want to use professional equipment like a regular radio station, it will be more complicated and not affordable for ordinary people. Mixers are digital mixers, condenser microphones and monitor headphones are several thousand dollars each, and audio workstations are not affordable for individuals. This is a big project.
