Narrative:

Our flight was cruising at its assigned altitude of FL320. We requested through hnl commercial radio, FL340, and turned off volume on HF, and were standing by for SELCAL on HF. Hnl commercial radio attempted contact thru HF SELCAL to inform us that our requested altitude was approved by ATC. We did not receive SELCAL transmission. Hnl commercial radio tried to contact us on VHF through relay from another aircraft in vicinity, however, VHF volume was inadvertently turned too low to hear transmission. We were out of communication with hnl for approximately 1 hour.

Title: HF COM LOST FOR 1 HOUR BETWEEN HAWAII AND MAINLAND.

Narrative: OUR FLT WAS CRUISING AT ITS ASSIGNED ALT OF FL320. WE REQUESTED THROUGH HNL COMMERCIAL RADIO, FL340, AND TURNED OFF VOLUME ON HF, AND WERE STANDING BY FOR SELCAL ON HF. HNL COMMERCIAL RADIO ATTEMPTED CONTACT THRU HF SELCAL TO INFORM US THAT OUR REQUESTED ALT WAS APPROVED BY ATC. WE DID NOT RECEIVE SELCAL XMISSION. HNL COMMERCIAL RADIO TRIED TO CONTACT US ON VHF THROUGH RELAY FROM ANOTHER ACFT IN VICINITY, HOWEVER, VHF VOLUME WAS INADVERTENTLY TURNED TOO LOW TO HEAR XMISSION. WE WERE OUT OF COM WITH HNL FOR APPROX 1 HR.
