Narrative:
On arrival at aircraft, mechanic was working on first officer communication control panel. After liftoff, unable to receive or transmit to ord. Squawked communication failure on transponder, maintained VFR on top and turned on course. Also attempted to listen on VOR. Relief pilot removed first officer's radio control panel and communication was restored to captain's side. ATC advised that communication failure was well done but squawk should have been 7600 versus 7500. Called company and suggested swapping second observer's panel for failed unit. After checking out the part numbers, company maintenance approved the swap. System restored to normal. Flight continued to destination.
