Narrative:

We were level at FL320 in trail of an MD80 and encountered wake turbulence with approximately 300 foot altitude deviation and 30 degree right roll. I turned off the autoplt and continued the right turn to gain separation. While this was happening; we coordinated the turn with ATC and requested a return to FL300. ATC gave us permission to descend and we continued the flight at FL300 for about 30 minutes and then climbed to flight plan altitude of FL340. The wake turbulence was encountered with proper in-trail spacing but our aircraft was 200-300 ft low due to all altimeters being set incorrectly. At transition altitude; the first officer was answering a call from the back and the captain was accepting a frequency change from center. During the radio and PA calls; the altimeter call was missed and remained at the field setting.

Title: AN MD80 FLT CREW ENCOUNTERED WAKE TURBULENCE FROM ANOTHER MD80 AT ALTITUDE; RESULTING IN ALT DEV AND ROLL.

Narrative: WE WERE LEVEL AT FL320 IN TRAIL OF AN MD80 AND ENCOUNTERED WAKE TURB WITH APPROX 300 FOOT ALTITUDE DEV AND 30 DEG R ROLL. I TURNED OFF THE AUTOPLT AND CONTINUED THE R TURN TO GAIN SEPARATION. WHILE THIS WAS HAPPENING; WE COORDINATED THE TURN WITH ATC AND REQUESTED A RETURN TO FL300. ATC GAVE US PERMISSION TO DSND AND WE CONTINUED THE FLT AT FL300 FOR ABOUT 30 MINUTES AND THEN CLBED TO FLT PLAN ALTITUDE OF FL340. THE WAKE TURB WAS ENCOUNTERED WITH PROPER IN-TRAIL SPACING BUT OUR ACFT WAS 200-300 FT LOW DUE TO ALL ALTIMETERS BEING SET INCORRECTLY. AT TRANSITION ALTITUDE; THE FO WAS ANSWERING A CALL FROM THE BACK AND THE CAPT WAS ACCEPTING A FREQUENCY CHANGE FROM CENTER. DURING THE RADIO AND PA CALLS; THE ALTIMETER CALL WAS MISSED AND REMAINED AT THE FIELD SETTING.
