Narrative:

During preflight at mco; I incorrectly xferred the departure control frequency from the ACARS pre departure clearance to the flight plan form. Correct frequency was 120.15 and I wrote down and selected 120.5. We departed runway 36L at mco with instructions to fly heading 010 degrees and a SID altitude of 5000 ft. I was the PF. After departure; we flew assigned heading and leveled at 5000 ft. I don't know what response PNF got when checking in with departure; but I never heard any xmissions from departure control while I was hand flying up to leveloff. After leveling at 5000 ft; we noticed we had no contact with departure control and were attempting to find the correct frequency. We then heard a call on VHF #2 on 121.5 from departure with a turn to 270 degrees and to contact him on 120.15. We immediately complied. We were in the turn when we contacted departure control. He said we caused traffic problems for him and others. I was surprised that we could have caused problems while so close to the airport on an assigned heading and altitude. (We were still south of the orl VOR.) I should have doublechked the departure frequency on ACARS pre departure clearance and the departure control frequency that I wrote down against the departure SID. This would have caught the error. I also think fatigue was a factor. I am a reserve pilot; and was on my 7TH duty day in 8 days. I just got off a trip with 2 consecutive nights of red-eye assignments (segments). I had 1 day of rest; and an XA05 morning departure on a 3 day trip into scheduled days off. I don't think I would have made this error if I had been better rested.

Title: FLT CREW OF B757 SELECT WRONG DEP FREQ OUT OF MCO. TFC CONFLICTS RESULT BEFORE MISTAKE CAN BE CORRECTED.

Narrative: DURING PREFLT AT MCO; I INCORRECTLY XFERRED THE DEP CTL FREQ FROM THE ACARS PDC TO THE FLT PLAN FORM. CORRECT FREQ WAS 120.15 AND I WROTE DOWN AND SELECTED 120.5. WE DEPARTED RWY 36L AT MCO WITH INSTRUCTIONS TO FLY HDG 010 DEGS AND A SID ALT OF 5000 FT. I WAS THE PF. AFTER DEP; WE FLEW ASSIGNED HDG AND LEVELED AT 5000 FT. I DON'T KNOW WHAT RESPONSE PNF GOT WHEN CHKING IN WITH DEP; BUT I NEVER HEARD ANY XMISSIONS FROM DEP CTL WHILE I WAS HAND FLYING UP TO LEVELOFF. AFTER LEVELING AT 5000 FT; WE NOTICED WE HAD NO CONTACT WITH DEP CTL AND WERE ATTEMPTING TO FIND THE CORRECT FREQ. WE THEN HEARD A CALL ON VHF #2 ON 121.5 FROM DEP WITH A TURN TO 270 DEGS AND TO CONTACT HIM ON 120.15. WE IMMEDIATELY COMPLIED. WE WERE IN THE TURN WHEN WE CONTACTED DEP CTL. HE SAID WE CAUSED TFC PROBS FOR HIM AND OTHERS. I WAS SURPRISED THAT WE COULD HAVE CAUSED PROBS WHILE SO CLOSE TO THE ARPT ON AN ASSIGNED HDG AND ALT. (WE WERE STILL S OF THE ORL VOR.) I SHOULD HAVE DOUBLECHKED THE DEP FREQ ON ACARS PDC AND THE DEP CTL FREQ THAT I WROTE DOWN AGAINST THE DEP SID. THIS WOULD HAVE CAUGHT THE ERROR. I ALSO THINK FATIGUE WAS A FACTOR. I AM A RESERVE PLT; AND WAS ON MY 7TH DUTY DAY IN 8 DAYS. I JUST GOT OFF A TRIP WITH 2 CONSECUTIVE NIGHTS OF RED-EYE ASSIGNMENTS (SEGMENTS). I HAD 1 DAY OF REST; AND AN XA05 MORNING DEP ON A 3 DAY TRIP INTO SCHEDULED DAYS OFF. I DON'T THINK I WOULD HAVE MADE THIS ERROR IF I HAD BEEN BETTER RESTED.
