Re: Radio 5 Live Echo (Empty Hall) Effect ?
The ear cannot hear time-of-arrival differences of less than about 100mS as an echo, so the difference of only a few millseconds in the time-of-arrival of radio transmissions carrying the same programme does not explain the perceived echo!
This is more likely to be caused by time-of-arrival differences caused as a result of using different methods for distribution of the programme to different transmitters, say land-line for one and satellite for another.

Dave.
