Whatever HF operator over the atlantic you are talking to, try call sign & frequency first, and you might ie add "position" if you intend to do a position report, but nothing more than that. This gives the operator time to switch to the correct frequency and prepare for you. He's not a controller, he's an operator monitoring multiple frequencies at the same time.
Once you get the get the "go ahead" from him/her you can throw in whatever you want to do/know. You will notice that on many occasions he already knows what you're after, and throw you some freq's and a selcal check without you having to ask for it. Things like CPDLC you do need to add though, because that' something they cannot know (as far as I've been told)
