I hope that Jerricho is correct and that there is no need for the "roger" after I have read back an instruction, because it sounds incongruous to say the least.
While we have the interest of some Canadian ATCOs here (and still loosely based on the thread title), could someone explain to me why we have to read our Oceanic clearances back even when we have requested them via ACARS and the clearance comes with an automatic "acknowledge" button to press? More importantly, could someone explain why I never get the clearance I request from Gander Oceanic by ACARS, but instead I get given the clearance that was filed on the flight plan?
I am just interested to know, because when we travel westbound, the complete opposite to the above occurs.
