Narrative:

I was working departure east radar when aircraft X checked in on my frequency. Aircraft X was filed to go out one of the western departure gates and should have been on the departure west frequency in accordance with the mem 7 departure procedure. I instructed aircraft X to contact the west departure controller on the appropriate frequency. On this occasion; nothing out of the ordinary occurred; but in the past this has led to problems including operrors; one of which was nearly a midair collision. Hopefully; someone will do something about the poorly written and displayed mem 7 departure before something even worse and more tragic happens.
