## Discrepancy

FLIGHT 483 SNA-OGG.  DURING CRUISE FLIGHT, THE CREW NOTED THE NR 2 HF RADIO WOULD NOT CHANNELIZE, BUT RECEPTION AND SELCAL OPERATED NORMAL.  CREW CONTINUED TO OGG WITHOUT FURTHER INCIDENT.  MAINTENANCE PLACED THE NR 2 HF ON MEL FOR THE AIRCRAFT TO FLY TO HNL.  MAINTENANCE REMOVED AND REPLACED THE NR 2 HF RECEIVER TRANSMITTER PER AMM 23-11-00-5.  THE NR 2 HF RADIO PASSED A GROUND OPERATIONAL CHECK AND THE AIRCRAFT WAS RETURNED TO SERVICE.  THE NR 2 HF RADIO SUCCESSFULLY PASSED A FLIGHT VERIFICATION CHECK ON THE NEXT FLIGHT LEG.
