What happened to Tacolneston tonight?

Several channels on different mixes off air but not all.

Becoming all too common.

Annoying: no threading.

BBC CH Four blocky and dropping out.

Anyone here who really understands transmitter problems?

For any contributor to this site to be able to offer any meaningful advice it is essential that you give a full post code. Only then can we determine the transmission and reception conditions local to your home.

High pressure weather affected Tacolneston reception in North Norfolk 29th. I suspect that the pressure enhanced the signal from the oxford transmitter which uses some of the same channels

no. The effect was like loss of signal on most channels . Worst on UHF channel 31 . affecting freeview 107 (BBC HDnews) etc . I suspect Oxford because it transmits half its multiplexes on the same UHF channels as Tacolneston at medium power. And is only about 20 degrees off Tacolneston in terms of bearing from central north Norfolk. In a couple of years time the plan is to move Tacolnestons channels away from Oxford

MikeP,

No need to give post code as I'm not asking about specific location.

If the transmission is dropping and/or s/s is low on only some channels it's the transmitter, atmospherics, nearby interference or user aerial system- in that order. In this case the problem was excellent s/s but zero quality so transmitter or (unlikely) atmospherics.

You guys always give the same answers: never the transmitter. In all my dealings with TV and radio reception transmitter faults have nearly always been the cause. Indeed, a couple of acquaintances were BBC transmission engineers and they said the same.

So, all I'm hoping to get is confirmation that others are having similar problems.

This site is a mine of information but it is terribly designed. For instance, why not use open source software to run a proper forum with threaded topics? I guarantee you will get better coverage immediately.

Mardler:

Transmitter problems are very rare and are normally dealt with quite speedily by Arqiva. Plus any such problem will normally affect all viewers who receive from that transmitter, not just one or two.

My fifty plus years experience show the opposite to yours as transmitter faults are rare. However, there are regular maintenance visits to them and during such it is not uncommon for there to be either reduced power operation or sometimes outages to protect the staff from extreme levels of RF radiation when they are close to the aerials.

In fact, there are more problems due to aerial systems at the reception end as they are generally poorly maintained - if at all.

MikeP: Mike, I totally agree - this statement:

'If the transmission is dropping and/or s/s is low on only some channels it's the transmitter, atmospherics, nearby interference or user aerial system- in that order.'

would seem to be the exact opposite of the reality of people asking questions on this site. Just trawl through the posts which ask about reception, and automatically assume that there is a problem with the transmitter, and demand that the BBC/Government/'them' do something about it, often accompanied by the phrase 'I pay my licence fee!'

When you ask the essential questions: 'what is the signal strength, have you checked with neighbours', and have you checked that all the wires are OK and not loose', your surprised at the lack of feedback, which is possibly largely explained by people checking out the rear of the TV and discovering that the aerial lead has fallen out of the back.

Discounting possible high pressure system problems (which do occur occasionally), when you check the actual status of the transmitter, its usually fine. Yes, there are delays in updating the information sometimes, where a rash of questions about reception lose predate a warning, but most of the time, the transmitter is fine. Even if its on lower power for a short period, that power level is still generally higher than pre-digital switchover levels.

Its strange that people automatically assume that a transmitter is at fault, even though it may serve many thousands of households and has generally backup systems, but discount totally that their system, which ultimately is linked together by wiring just 6mm wide, has plenty of joins in it, may have been installed by the biggest bodgers on the planet, and has an aerial which might be in place for decades battered by all the weather can throw at it should be totally fine. Its a TV Occams Razor.

The point is high pressure reception can DECREASE the apparent amount of signal received. The local and interfering signals do not necessarily add . Sometimes because interference looks like electrical noise the total signal appears smaller . (technically called reduced signal to noise ratio) At other times the same atmospheric condition that lifts distant signals will kill the local signal.
Note I have an academic qualification in telecommunications . Do not work for any tv service so am not part of the transmitter workers "conspiracy"

Your comment please
Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
