It is simple to add a own Rdio-Station to the bot. U have to open the /sinusbot/data/radio.json with an editor like Notepad++. If u opened the file with Notepad++ you have to see 1 long line. Now scroll to the end. Now you have to see "}]}" at the end, add a comma like this "},}]" and after the comma you have to add this ( pls edit it before )
{"n":"name_of_the_station","u":"stream_url_of_the_station","t":"type of the stream like acc, mp3","g":"description what the radio play like pop,rock,metal,etc","c":"comment","b":"bitrate_of the radio"}
for your example you have to add this
{"n":"Radio 538","u":"
http://radio.weatherusa.net:80/NWR/WNG676.mp3","t":"audio/mpeg","g":"daily music","c":"My favorite stream","b":"128"}
i am not sure about the stream_url and the bit_rate.
After you have added this restart the bot and search the Radio in the interface. Normally it work, if you do all right. I am using this for my bot..
But the simple way is to add your name to the admin account in the interface and write the bot in TeamSpeak in a private message "!stream stream_url"
