Perhaps an artificial intelligence can help automate your station? They work for free, 24/7/365. Sara, the AIVMS AI
, can even announce news, weather and traffic reports just like a normal radio station, along with user definable song introductions.
A nice feature is that you or any other internet user can call into the station and connect with her Skype VOIP client to make "on-air" announcements, song requests, etc..
Sara will automatically answer incoming calls and prompt the caller (Hello, you are on the air live). She will then pause the broadcast, and route the VOIP audio to the internet stream. When the call is complete she will resume the broadcast.
You can download AIVMS
and try it out for yourself to see if it will meet your needs. Once installed, just select the "DeeJ" command from her menu if you do not have a mic to issue voice commands.
