QNH

[Ropey Pilot]

Have those who are trying to fit words to the codes read the initial link by albatross?

There may be well known mnemonics to aid memory of often used codes - and possibly even assisted in their initial allocation, but essentially the codes came before the widely used 'memory aids' - one only has to look at the number of them to seee that they cannot all stand for something.
Possibly those who only hear QHN/QFE don't realise the number of others and assume those two must have a meaning.

Even today - in the ATPL we have (including mnemonics I was taught):
QDM: Mag heading to [Direct Magnetic]
QDR: Mag Bearing from [Direct Radial]
QTE: True bearing from [True Eminanting (from)]
QUJ: True track to [True to the flag (Union Jack - starting to reach a bit I know!)]

And I have certainly used:
QSY: Leaving frequency (normally with mil controllers)
QGH: According to the link it is simply asking for clearance to use an approach - I was under the impression it was itself a specific type of approach where ATC homes in on your tranmission (instead or RADAR) and talks you down. Done a few (with real RADAR backup - I may be stupid but I'm not suicidal!)

HD, from albatrosses link:
QNE: What indication will my altimeter give on landing at ... (place) at ... hours, my sub-scale being set to 1013.2 millibars (29.92 inches)?

On landing at ... (place) at ... hours, with your sub-scale being set to 1013.2 millibars (29.92 inches), your altimeter will indicate ... (figures and units).
