Keith Burrell / et al : The tropospheric ducting forecast maps (Ak William Hepburn) indicates that parts of the UK is presently being affected by high pressure, a condition which allows the reception of transmissions from distant stations, which if on the same frequency as that used by a local station will result in either same being wiped out, or alternatively causing erratic reception due to the alien signal corrupting the quality of the signal from the local station.

Unfortunately nothing can be done to alleviate this type of problem, and I may say, is one which I am sure is going to be a cause of complaint for many over this coming week, as the pressure zones are forecast to affect most areas in the UK at some point in time.

Mark Elvidge: Hi Mark. There are no issues with either the Belmont or Bilsdale West Moor main transmitters this morning that would require the attention of engineers, so it is unfair for any heads to be rolled! What is apparent, however, is that the UK has high atmospheric pressure conditions which can cause transmitters in the UK (or abroad) which use the same channels to interfere with one another. We call this, "co-channel interference" or "CCI". It has the effect of corrupting the quality of your received signal to the extent that you may experience picture freeze and loss of sound on your Freeview channels. Unfortunately, there is nothing that can be done to overcome the effects of high pressure; the viewer simply has to wait until lower pressure conditions prevail - which could be a matter of waiting several days. In the meantime, one could view television online instead of using Freeview, or one could invest in a 'Freesat' setup. You are, of course, entitled to contact programme providers, to inform them of your issues, but I anticipate you will get a similar response to mine. I am sorry that I could not have been of more assistance to you, Mark. Regards, Richard, Norwich, Monday 6th. June, 10:45 a.m.

D.M.Rion.:
Loss of 554 Mhz CH 31 HD channels update.
I switched on again today and found the lost HD channels back on,
I had re-tuned my television last night to no avail and even lost the channels from the EPG listings.
Luckily i didn't do this on the dvd/blu-ray recorder, i just left it has it was, thats how i knew the channels were back on this morning.
I have just re re-tuned the television & all the missing channels are there with a stronger signal than before.
I see others have posted comments about "High pressure" weather conditions as why there were problems with the signal last night. However, i can only speak for myself in this, this morning when i switched on the television & dvd/blu-ray recorder and checked the signal strength in the settings i found the signal to show a higher reading than before the loss occurred. Maybe there was a problem with the Waltham transmitter after all, as well as the "High pressure" weather condition.

Ed and Alan:

There are no analogue TV transmissions from Waltham! They are all digitally encoded these days and formed into multiplexes carrying several channel services. So when you say there were no analogue signals, I'm not at all surprised as they finished more than 5 years ago and in some cases nearly 10 years ago!

Poor / no reception started in Leicester LE9 area at 10.15pm on Sunday 5 June and continued this morning, Monday 6 June. An independent aerial specialist came out and advised that he and all other aerial specialists received a message advising of an issue. It cost us ?25 in labour charges for a 2 minute test by the aerial specialist who confirmed the problem was not our aerial. Before we booked the specialist we checked online and there were no recorded problems! The specialist confirmed he had been 'inundated' with calls this morning. He also told me that problems with transmitters are almost never recorded on transmitter websites, unlike electricity, gas, flooding, water websites where there is some transparency in service glitches.

Shame that the transmitter people do not feel the need to communicate issues to customers but at least our local aerial specialists are quids in!

S. Harrison : I would have thought that your independent aerial specialist would have been aware that the reason for numerous complaints over the last few days from both Waltham and stations covering other areas is not connected with transmission problems, but a series of high pressure zones sweeping around many parts of the country, high pressure being a condition which allows the reception of transmissions from distant stations of not only within the UK, but also outside of such as Europe.

The problem being, if one of the said transmissions happens to be on the same frequency as one of the multiplexes on the station normally used for reception, this will either result in same being wiped out, or alternatively erratic reception due to the alien signal corrupting the quality of the signal from the local station, evidenced (in some cases) by witnessing pulsed variations in signal quality accompanied by a reasonably high signal level.

Unfortunately nothing can be done to alleviate this type of problem, and which I may say, is one I am sure is going to result in numerous complaints about bad reception over this coming week, as the pressure zones are
forecast to affect most areas in the UK at some point in time, and at times, on more than one occasion.

MikeP: Just to put you into the picture about my sister's errant Philips TV. She tried the no aerial clearout and rescan technique but no change. She called back the aerial installer who repeated everything I did and came to the conclusion that the TV's firmware was out of date with current Freeview standards which is strange but plausible and recommended an external STB. As I said previously my STB which I just happened to have with me performed perfectly and I don't think it has had a firmware update for at least 4 years but something is odd with the Philips TV not doing the usual trick of putting duplicate channels from multiple transmitters in the 800's and putting at least one in the correct location.

There is a difference between 'Poor Quality' due to co-channel interference (which is often a combination of the interfering signal's phase, strength, aerial alignment factors) and the state 'No Signal'. Also the local transmitter's signal propagation range is affected by the ground and atmospheric conditions so weak signal areas loose the signal completely. Most users are able to access their Signal Quality / Reception displays on their Television which differentiate between the 2 signal conditions. Selecting an alternate Channel which is working from the same transmitter site proves the customer's aerial and the rest of your equipment is O.K and it is a reasonable assumption the fault lies with the transmission.
1. Can we not get an article from an engineer / technician who works on the transmitter equipment itself to explain the monitoring of service, how failure status is reported to the control room (SCADA systems etc) and what is the Service Contract demand for repair.
2. Who is in charge of the Transmitter Service fault reporting on this website and who sends in the information during normal work hours and 'out of hours'.......how does this detail get updated on website. What is a better website for this information?
3. Formal contact details stated on website for 'loss of service' reporting on digital channels.
4. How does the lower power levels of the digital transmitters and their frequencies / channels get decided upon and who monitors the impact of atmospheric conditions leading to co - channel interference effects, often from other UK areas using the same channels. Where are these warnings published?

Keith Burrell: Hi, Keith. I can try to answer some of your questions. The majority of broadcast transmitters are run and maintained by Arqiva, which, has strategically placed centres from which engineers go out to attend to transmitter faults, one of these being 'Emley Moor'. Arqiva, as an organisation, seems to have what one might call a 'closed', 'opaque', 'high privacy' philosophy, seemingly unwilling to share information or make it public, perhaps because of terrorist threat worries? I would be surprised if Briantist could persuade an Arqiva transmitter maintenance engineer to explain his work to us, because the engineer would probably be breaking a confidentiality clause in his contract if he did so, and would be summarily dismissed! I think you will find that website owner, Briantist, is responsible for transmitter fault reporting on this website. The information is generally publicly available if you know what you are looking for and where to look, for example, the radio and transmitter investigation service website, run by the BBC, will tell you the transmitter status for all types of broadcast tv and radio, for every postcode in the UK where there is an available service. Other good sources of information are the digital uk website for Freeview tv and ukdigital radio or getdigital radio for digital radio. In answer to your question 3., you'll have to ask Briantist. The power levels and frequencies/channels are determined by international agreements and probably monitored by the UK regulator, Ofcom. Richard, Norwich.
