Narrative:

During a charter flight; our HF radio could not transmit to report our position. One HF was under MEL and the other had tested good to transmit and receive from ZZZ radio. When we discovered airinc could no longer hear our transmissions we used a part 121 aircraft in the area to relay our positions for us. Once we arrived at ZZZZ it was determined that they have no avionics repair capabilities on the island. Our company; a part 135 air carrier; decided to MEL the other HF and to issue a one-time ferry permit authorizing us to ferry the plane to a us radio repair shop. We noted on the flight plan in the remarks that we had no HF and would be making position reports via sat-phone. Upon taking off [and] talking to center on VHF we again stated our situation and that we are on a ferry permit to get to a maintenance shop capable of HF repair. The controller stated after a delay that an HF radio is required equipment and that she was going to forward our message on to oceanic but also added that paperwork was going to be filed about our flight. I am now concerned that company may have overstepped its authority in issuing the ferry permit without first clearing it with oceanic. In the future if a situation like this ever presents itself again; oceanic absolutely must be involved in the process; we need them on the same page as us.
