You could use a batch file... Dunno if you have any experience with batch files.
For example:
DJs.bat:
echo DJ Name 1 > C:\rds.txt
sleep 7200
echo DJ Name 2 > C:\rds.txt
sleep 7200
echo DJ Name 3 > C:\rds.txt
sleep 7200
echo Non-stop > C:\rds.txt
sleep 64800
DJs
What this does:
- Set text "DJ Name 1" in the file C:\rds.txt
- Wait 7200 seconds (2 hours)
...
The 24 * 3600 (1 day) - 3 * 7200 (the 3 DJ names) = 64800 seconds, so that makes sure that the next day you get the same times.
Then it starts DJs again.
Note:
- You'll have to start it at exactly the right moment.
- After a while you'll get an offset, after a few weeks you may need to restart it.
Note: You'll need a separate executable "sleep" for this to work! Can be found among others as part of the Unix Utilities (Windows port):

Maybe someone else can give a better (easier, more user friendly) solution...
