Narrative:

An E145 contacted me on the departure west frequency. The route of flight for aircraft X was such that the pilots should have contacted east departure. Later; an A319 contacted the departure west controller. The route of flight for aircraft Y was such that the pilots should have contacted the east departure controller. The FAA says that this happens (aircraft using the wrong frequency for the mem 7 departure) infrequently. I send in these reports to show that it happens multiple times on a daily basis. The FAA has made several changes to controller procedures at mem due to an near midair collision between aircraft that had the wrong frequency; but nothing has been done to address the real problem of pilots not getting the proper frequency from the mem 7 chart. I have made several suggestions in the past. I wish someone would do something.

Title: MEM DEP CTLR DESCRIBED REPEATED EVENTS WHEN DEP ACFT ATTEMPT TO ESTABLISH CONTACT ON THE WRONG DEP FREQ.

Narrative: AN E145 CONTACTED ME ON THE DEP W FREQ. THE RTE OF FLT FOR ACFT X WAS SUCH THAT THE PLTS SHOULD HAVE CONTACTED E DEP. LATER; AN A319 CONTACTED THE DEP W CTLR. THE RTE OF FLT FOR ACFT Y WAS SUCH THAT THE PLTS SHOULD HAVE CONTACTED THE E DEP CTLR. THE FAA SAYS THAT THIS HAPPENS (ACFT USING THE WRONG FREQ FOR THE MEM 7 DEP) INFREQUENTLY. I SEND IN THESE RPTS TO SHOW THAT IT HAPPENS MULTIPLE TIMES ON A DAILY BASIS. THE FAA HAS MADE SEVERAL CHANGES TO CTLR PROCS AT MEM DUE TO AN NMAC BTWN ACFT THAT HAD THE WRONG FREQ; BUT NOTHING HAS BEEN DONE TO ADDRESS THE REAL PROB OF PLTS NOT GETTING THE PROPER FREQ FROM THE MEM 7 CHART. I HAVE MADE SEVERAL SUGGESTIONS IN THE PAST. I WISH SOMEONE WOULD DO SOMETHING.
