I initially remembered these as QFE = Field Elevation and QNH = Nautical Height which served me quite well.
I also recall seeing the following explanations which helped me, the first of which you've mentioned already. Although I'm just passing on what I've read elsewhere (or possibly on here) so I've no idea whether this is how they were originally derived:
QDM = Direction Magnetic (to the station)
QDR = Direction of Radial (thus magnetic bearing from the station)
QTE = True Emanation (true bearing from the station)
Where on earth we get QUJ from I don't know...!
