David Nash: Yes, I would be interested to know the outcome of the "short wire" instead of aerial test, as obviously the signal level being fed into the Wolsey amp from the wire aerial would be a great deal less than from the aerial and I was curious as to whether the amp would still lock up or not, because if it didn't, then an attenuator could be placed in line between the aerial and the amplifiers input.

The undermentioned links are for an SLX 6 way distribution amplifier with built in 4G protection, the second link being for the same amp but with a more detailed specification being given. (by clicking on "specification")

We recently went to stay in Hertford, looking forward to seeing Look East again after many years. The Sandy Heath signal was great, especially as Crystal Palace seemed to drop out a lot and the BBC London News was almost exclusively London-Centric. Something strange kept happening during the BBC One O'clock news that makes me wonder how the Sandy heath transmitter is fed with the right regional service - At the start of the programme there is a ten second opt out for regions to say what is coming up in their own news. Bearing in mind we were definitely tuned to BBC East (W), the picture and sound defaulted to BBC NEWS CHANNEL with a sport preview, and the subtitles gave a printed version of what we could expect on BBC LONDON NEWS. Then, at the right point at the end of the news, BBC LOOK EAST dutifully appeared! A bit confusing, and I expect the majority of viewers might not care, but is there a good reason for it happening like that?

Jonathan Snowden: If it's happened just the once then I'd say it was some administrative error in feeding the feeds where they should be fed.

Perhaps the "master" feed is that which is given to BBC News channel and that the BBC East opt-out wasn't slipped in -- maybe the presenter was talking to the camera but no one was watching!

Jonathan Snowden: How often did it happen for? Perhaps the opt-out switch is automated and the thing was not set-up correctly and it took them however long to become aware of this.

Dave Lindsay: Hi, we were there for a week, and it happened each weekday. During the six o'clock everything seemed to be OK at the beginning and the halfway point when they have to tiny regional opt outs to say what's coming up.

w mc bride: Ballycastle is only a "public services" relay transmitter of the Limavady main station. Relay transmitters do not broadcast commercial "run for profit" channels paid for by advertisers, the reason for not doing so basically down to the fact of the advertisers not being willing to pay for transmission facilities in areas of lower populations, as its considered by them that the profit expected from running such channels would not justify the costs involved.

daniel tristan : You should try retuning your TV whilst it temporarily connected into the aerial point used by your Mums TV, should this fail to make any difference to the situation, then carry out a "reset" on your TV (or box) followed by a second retune.

The reset referred to also known as "default setting" / "first time installation" etc.
