Nothing. It's just a code, the Q-code, to be precise :-) Maybe the Q has
a story, I don't know, but the latter two letters definitely do not.
Think of it as a numbered set of commonly used phrases.

Don't forget the Z codes.

They are all simple codes originally sent by morse. If you look at the
whole list there are loads of things to do with radio comms as well as
the various things to do with aerial navigation.

They are widely used in amateur radio as well as in flying.

Quite right. One may send quite a complex message using a few Q & Z
signals, text, and numbers.

Thanks to all who've helped me understand the orign of the letters in
QNH, QFE, QNE, QUH, WTF...etc...

One of my aerospace co-workers (and a fellow Flight Test Engineer) was
musing aloud one day: "We all know what it MEANS, but what do the
letters STAND for??? Where did they come from?" As if QNH stood for
"Quintesstial Normalized Height," and QFE stood for "Quiet Field
Elevation," or ???

I tried to warn him that it was foolish to try and make sense out of
any three letters...take "FAA," for example... ;-)
