A question for you, London ATC controllers :
Compared to the others European countries, the UK ATC radio transmitters have a very poor quality. Any improvement in the future ?

Kirk... my comments on the QNH etc are still valid. You seem to have missed my point in that many of the items/phrases we read back these days have little validity in todays airspace management situation. They just occupy airtime for little practical use.
Reading back the QNH has never prevented a known accident! Setting the wrong one may have caused one, but that is a pilot procedure - not a function of ATC. In a multicrew airliner SOPS should cover such things off within the flight deck.
The bottom line is that the ICAO recommended phrases are way out of date and need to be reviewed. On the other hand, if everyone even used them it would be better!

Fly_by_night. The UK area systems use slightly offset frequencies from 2 or 3 transmitters at different sites. It is normally a function of the receiver if the quality is poor - not all are very good at deciphering this method of transmission. The audio quality is now worse than a few years ago,I think, due to the change in headsets used at LATCC.

Triadic- you are showing your location a bit. In Oz, where everyone is more or less on the same page, readbacks very rarely show up errors. But in busy multicultural environments, where English can be the second or third language in use, it is critical to have readbacks. Many errors detected.
As to mode c, it is necessary to validate it because different agencies use different equipment- Dubai App. even uses diff. to ACC. Data link is even more fraught with danger than voice- ask the guys who use it in OZ oceanic and West group and have to suffer the monthly round of 'look at all the messages that were misinterpreted and could have gone horribly wrong'.
