Are you asking about the Official Q-code lists as defined by International

or
Common usage by Amateur Radio Operators ?

Official Q-codes are at URL:

Okay, that is a typical source I've seen. Now look at the specific
entries:

# QTH My position is ... latitude, ... longitude (or according to
# any other indication).

"My" Lat/Long.

# QTF The position of your station according to the bearings taken
# by the D/F stations which I control was ... latitude, ...
# longitude (or other indication of position), class ...

"Your" Lat/Long.
Both *seem* pretty clear.

----------

# QRA The name of my vessel (or station) is ...

Other ham sites imply this denotes grid square coordinates
("locator")--okay, that is just variation in common usage.

----------

# QGE Your distance to my station (or to ...) is ... (distance
# figures and units).

More "precise" geodetic (ellipsoidal) distance (for official
competitions, etc.)?

# QRB The approximate distance between our stations is ... nautical
# miles (or km).

Casual/informal spherical distance for general purposes?

----------

# QTE Your TRUE bearing from me is ... degrees at ... hours.
# or
# Your TRUE bearing from ... (call sign) was ... degrees
# at ... hours.
# or
# The TRUE bearing of ... (call sign) from ... (call sign)
# was ... degrees at ... hours.

Straight forward: "Your" azimuth/bearing to "me" (i.e., the "reverse
azimuth").
Or, is QTE for *both* the forward/obverse ("me" to "you") *and* reverse
azimuth?
If not,

# QTI My TRUE track is ... degrees. [AP13]
# QTI* My TRUE course is ... degrees. [AP14]

# QTL* My TRUE heading is ... degrees.

which (if either) of these would denote the obverse azimuth?
