“Roger” or “Copy” or neither

Yep, QNH is still sea level pressure - 1013.2 millibars or HPa in modern language.

Thank you. My question was what the "NH" used to mean.

1013.2 is "standard", from the International Standard Atmosphere and is not the same as QNH which can vary by the hour. When setting 1013.2, you are flying at a Flight Level, on QNH, it's an altitude. On QFE, a height (above the airfield).

Ohh be careful. The QNH is not a fixed value. It’s a local setting based on local sea level pressure. 1013 or 2992 if you like spam is a Standard setting used when above the local transition level so the all aircraft fly at heights ( known as flight levels) relative to each other .
Of course 1013 could by coincidence be the local QNH.

Roger is quite a useful term. I don’t get the use of “over” but “out” makes sense - to means I’ve finished talking and I don’t expect you to be listening out for me any more so I don’t have to say when I’m leaving the frequency/shutting down for the night.

With a normal duplex call the conversation normally runs smoothly as it doesn't matter if they talk over each other, but with a simplex channel 'over' is necessary and acts as a prompt to speed up calls. Without it, a recipient wouldn't know when it was his turn to reply without waiting for a long enough pause. It can feel tiresome to a beginner but should feel natural.

Mornington Crescent!

The CQR was, of course, developed by Sir Geoffrey Ingram Taylor, a professor of engineering and pilot who had worked at Farnbrough during the First World War. He seems to have had at least one eye on an intended use by seaplanes and flying boats.
 
If any one used Roger on my boat I consider some one's calling me to start a conversation not closing down a conversion.

If its crew I has then what do they won't, and the must put 10 quid in the drink's kitty
