What are the channels and names for all the kpop music?

Like every Saturday I watch Music Core but I don't know what time it comes on because i always go in the middle.And its on MBC. I also watch The M Wave on Sundays and same as the other IDK the time. And I have other Korean channels on my TV but I don't know if they have Mnet Countdown or w/e. And i want info on Inkigayo or Gayo dayum?
