The symbol shows the location of the Bristol Kings Weston (City of Bristol, England) transmitter which serves 18,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
Are there any planned engineering works or unexpected transmitter faults on the Bristol Kings Weston (City of Bristol, England) mast?

Hmmm - I wonder if this could be the issue!!! <quote>Some types of roofing material are semi porous and the attenuation level can rise if they get wet,</quote>
The signal took a couple of days after the rain to come back to normal: the roof tiles are 70yr old terracotta (hopefully soon to be be replaced) so could well be absorbing moisture and causing the probs.
Seems feasible.....

Geoff Gaunt: Actually check the signal path. Occam's razor says the the simplest explaination is probably the most likely. It might be the tiles, but its much more likely that you have a leak....

Geoff Gaunt: Mike - definitely no leak/damp in the loft space. No way any moisture can get into the aerial/connectors/cabling which all run internally.
It's the fact that the degraded signal lasted for a couple of days after the heavy rain event before coming good again which may indicate the (old) tiles are absorbing moisture.
PSB1 signal strength is now showing 54% (sunshine on the roof :-), it was 53% yesterday and 48% when signal was lost)
I guess the ultimate solution is to get the aerial outside if it becomes a regular occurrence.

Geoff Gaunt: What was your signal strength when you put the aerial in? The wet tiles might well be having a dampening effect, but the signal strength loss seems to be only about 6% - so perhaps your on the margin anyway, and the wet tiles are pushing the system under the treshold for a decent signal.
Put your postcode into the site - if you should get a fantastic signal according to the predictors, and your not (OK, so loft aerials are as much magic as science), then its not the wet tiles, but something else.
Yes, a roof mounted aerial would be better, but it might be your setup is fine, but its a little under the weather at the moment.

Reception on channel 60 at this location is very poor. All other multiplexes are 100%. My aerial is wideband and on the roof. I have tuned the TV properly. When will this frequency be moved from the 700 series to make way for mobile?

To answer you we need the requested full post code. There are several transmitter around the Bristol area and you may be receiving from one of the others rather than Kings Weston Hill.

We have two TVs in our house, both connected to our aerial aligned to Bristol Kings Weston transmitter. Usually we have good reception on all channels on both TVs.
Recently, we have been getting poor reception ( pixellation, breaks in sound etc) on BBC1, BBC2, BBC 4, BBC News, BBC Parliament (all things on the BBC A Mux) on one of the two TVs -this is a small JVC TV about 1 year old. Other channels on that TV seem OK.
Our other TV, which is a large Samsung about 4 years old, still has good reception on ALL channels.
The JVC TV has a signal strength/quality indicator which shows quality of 50-60% on BBC A Mux, but 100% on all the other Mux. The Samsung does not have the same signal strength/quality indicator, but does show a bit error level of zero on BBC1, BBC 2 etc.
Could it be a temporary signal quality problem on the BBCA Mux from Kings Weston, that is enough to upset the JVC TV but not the Samsung? Do I need to report this? How do I do that?

David Ward:
When comparing the JVC 'Quality' and the Samsung 'Bit Error Rate' are you doing this at exactly the same time? Is the JVC still the same now?
The reason for asking is there's been some Tropospheric Propagation over recent days which has affected TV reception for lots of people in varying parts of the country at varying times. It may be that the JVC tuner is not quite as good as the Samsung at decoding the signal under certain interference conditions.
Other possibilities - What is the Signal strength on the JVC, and is there a strength reading for the Samsung? It's possible that if there is interference coming in, it might just be enough in addition to the usual signals to cause some tuner front end overload.
Also check all your coax connections. I assume you have some sort of splitter to give the two outputs, try swapping them over, likewise check out any flyleads by swapping if you don't have a spare. It is possible for such faults etc to affect only one multiplex.
I would have thought it unlikely there's any fault at the transmitter, I would have expected to see more people with problems, I can't find anything reported by the BBC or Freeview, and the transmitter isn't listed for Planned Engineering.

My sister-in-law who lives in Westbury-on-Trym, Bristol, has lost the TBN channel 65 on her list. It is not there at all though other channels are unaffected. Have you any explanation please?

Mrs Humphreys: TBN has moved to the PSB3 multiplex which carries BBC 1 HD, BBC 2 HD, ITV HD, Channel 4 HD, Channel 5 HD & CBBC HD and can only be received on TVs which receive these HD channels. If your sister-in-law can receive those HD channels, she should be able to restore TBN by retuning.
