Hi, I am having signal problems; since Saturday the BBC Mux (Craigkelly) is either so blocky one cannot watch it or non-existent at all (99% strength, 0% quality; all I get is a black screen on BBC1 etc). Mr Aerial Man is visiting in the afternoon and we will try to point the DAT45 upwards to miss the trees that we suspect cause the problem. I think we will need all the help we can get, so I noticed the "Extended Signal" option on the Toppy. It is not documented in the manual so I thought I would ask. It appears to beep as well as enlarge the quality/strength window; what does the beeping mean? TIA!
