## Discrepancy

THE CREW CALLED IN WITH THE PTT SWITCHES STICKING WHEN SELECTED ON TRANSMITT MODE AND A FAINT BURNING SMELL.  CONTACT MAINTENANCE WAS CALLED AND RERACKED THE REMOTE ELECTRONICS UNIT AND THE CAPTAINS SIDE STARTED WORKING, SO THE AIRCRAFT WAS FERRIED TO PHX FOR FURTHER REPAIRS.  MAINTENANCE REPLACED THE AUDIO REMOTE CONTROL UNIT.
