MD80's aircraft with clearance to cross intersection on localizer approach started descent using DME from the previously set VOR. Approach controller reminded flight crew of altitude restr and they then realized the wrong VOR was tuned, set the right one and climbed back to intercept altitude.

Narrative:
Chicago approach gave us 160 degree heading intercept runway 22R localizer cross fnuch at 7000 ft. I read the clearance back and set the first officer up on the localizer frequency inbound. The controller then gave us slow to 170 KTS fnuch at 7000 ft hold 170 KTS to ridge tower 120.75 at ridge. I read the clearance back as we intercepted the localizer. At what we thought was 19.5 DME we started down to 5000 ft. At 6500 ft the controller repeated cross fnuch at 7000 ft. At this point I realized that I had not changed the VOR from obk to ord and we climbed back to 7000 ft. We were now at fnuch and continued the approach.
Original NASA ASRS Text
Title: MD80'S ACFT WITH CLRNC TO CROSS INTXN ON LOC APCH STARTED DSCNT USING DME FROM THE PREVIOUSLY SET VOR. APCH CTLR REMINDED FLC OF ALT RESTR AND THEY THEN REALIZED THE WRONG VOR WAS TUNED, SET THE RIGHT ONE AND CLBED BACK TO INTERCEPT ALT.
Narrative: CHICAGO APCH GAVE US 160 DEG HDG INTERCEPT RWY 22R LOC CROSS FNUCH AT 7000 FT. I READ THE CLRNC BACK AND SET THE FO UP ON THE LOC FREQ INBOUND. THE CTLR THEN GAVE US SLOW TO 170 KTS FNUCH AT 7000 FT HOLD 170 KTS TO RIDGE TWR 120.75 AT RIDGE. I READ THE CLRNC BACK AS WE INTERCEPTED THE LOC. AT WHAT WE THOUGHT WAS 19.5 DME WE STARTED DOWN TO 5000 FT. AT 6500 FT THE CTLR REPEATED CROSS FNUCH AT 7000 FT. AT THIS POINT I REALIZED THAT I HAD NOT CHANGED THE VOR FROM OBK TO ORD AND WE CLBED BACK TO 7000 FT. WE WERE NOW AT FNUCH AND CONTINUED THE APCH.
