## Discrepancy

PHX  FLT 807  EN-ROUTE PHX TO HNL.  THE CREW COULD NOT GET THE AIRCRAFT HF RADIOS TO TRANSMIT OR RECEIVE, REPORTING: "TRANSMISSION AND RECEPTION ON R HF AT 5547, 8843 KHZ INOP (OCCASIONAL XMISSIONS ON 5547, WEAK)" AND "TRANSMISSION AND RECEPTION ON L HJF AT 5547, 8843 KHZ INOP".  MAINTENANCE AND DISPATCH WERE CONSULTED.  A CIRCUIT BREAKER RESET ONLY BROUGHT BACK HF RADIO RECEIVING CAPABILITY.  THE FLIGHT COULD NOT CONTINUE ETOPS OPERATION, SO IT RETURNED TO PHX.  A DECISION WAS MADE TO LAND OVERWEIGHT DUE TO TURBULENCE IN THE AREA.  AN EMERGENCY WAS REPORTED TO HAVE BEEN DECLARED.  NO FAULTS FOUND.
