## Discrepancy

AIRCRAFT EXPERIENCED AN IN-FLIGHT COMMUNICATION MALFUNCTION. THE AIRCRAFT’S COMMUNICATION SYSTEM BECAME STUCK IN THE TRANSMITTING (TX) POSITION, PREVENTING THE CREW FROM RECEIVING ANY TRANSMISSIONS AND EFFECTIVELY BLOCKING THE ACTIVE FREQUENCY. TROUBLESHOOTING WAS  ATTEMPTED BY SWITCHING BETWEEN COM1 AND COM2; HOWEVER, THE ISSUE PERSISTED. AS A RESULT, THE CREW ELECTED TO SQUAWK 7600 TO NOTIFY ATC OF A LOSS OF COMMUNICATIONS. INTERMITTENTLY, THE CREW WAS ABLE TO RECEIVE (RX) TRANSMISSIONS FROM ATC AND RECEIVED FURTHER INSTRUCTIONS IN THE EVENT COMMUNICATIONS WERE LOST AGAIN. THE FLIGHT CONTINUED AND LANDED SAFELY IN HONOLULU.
