## Discrepancy

HF NR 2 RADIO TAKES EXCESSIVELY LONG TO CHANNELIZE AND WILL NOT TRANSMIT.  ELECTRICAL SMELL NOTED DURING CHANELIZATION PROCESS, BUT DISIPATED AFTER HF WAS TUNED.  MAINTENANCE INSPECTED HF RELATED WIRING AND CONNECTION AND COULD NOT FIND A FAULT.  THE HF NR 2 TRANSCEIVER AND BOTH CONTROL PANELS WERE REPLACED AS A PRECAUTION.
