I have been checking the Digital UK website for months now and every time I go on there, it says there are Planned Engineering Works at Bluebell Hill with "Possible Weak signal". Does this mean that there is a known problem with the transmitter but it is not being fixed? Or is it false information? How can I find out?
From my point of view it is very frustrating because my problems started immediately after the retune on July 19th last year when they carried out changes for 700mhz clearance. I have watched through hours of recorded programs to test this, and there is no doubt that all recordings before that date are problem free, whereas recordings after that date have frequent glitches along with loss of picture/sound.
I have tried attenuating the signal strength back to around 80% as suggested by MikeP because I am within 2km of transmitter. This had no effect or if anything made it slightly worse due to dropping back the signal quality as well as strength. The signal quality fluctuates then drops out giving brief "no signal" message before recovering back to it's peak. The peak also fluctuates from one day to the next.
I have also replaced the wall socket and renewed all cables inside the house, which made a slight improvement but not enough to eliminate the issue. The only thing left is the aerial, which is old but exactly the same as everyone elses around here and pointing in the same direction. I live in a rented house and cannot afford to replace it, and besides, it was perfectly adequate before July 19th 2018.
Sorry for the lengthy post, but I am desperate to get this resolved after 7 months of patiently waiting for the freeview engineers to sort the problem.
Is there anything I can check between the rooftop aerial and the wall socket that may help?
Thanks

Ask Arqiva direcrtly as they operate thew transmitters and will know what plans there are for any engineering work.

You make a good point about the Planned Engineering listing, DigitalUK are the ones to ask about how accurate those listings are (tel:03456 505050). I only look myself if I become aware of a possible issue! Virtually every (main and some relay) transmtters have some supposed work at present ! I must admit I find that a bit difficult to believe although there are further clearance changes to come over the next 2 years but not at Bluebell Hill AFAIK. If anything is going on there it may be "tweaking" or some other difficulty that doesn't have a quick fix (eg. faulty antenna). As MikeP has suggested Arqiva would be the people to ask (try 01962 823434) if DigitalUK don't know (or give you BS).
If you have a wideband or group T aerial then reception shouldn't be an issue but it's worth checking the system out, your downlead may have degraded etc and the frequency changes could have caused any issues to come to light. It is perfectly possible for individual UHF frequencies to be affected by damaged cable rather than all frequencies. If your issue is mainly with the higher UHF channels then damp in the cable might be a cause, but again any frequency could be affected more than another.
Also remember the current high pressure weather is causing periodic reception problems (continental interference, but also possibly some uk transmitters that are now sharing more frequencies).

Forgot to say, you mentioned HD channels, if you are specifically referring to those on COMs 7 & 8, they are on the SFN channels 55 & 56, I'd want to be sure the downlead was in good order.
Also it would be worth considering whether you have too much signal as you are so close to the transmitter. If the front ends of receivers are overloaded beyond a certain point (this can vary from brand/set to brand/set) they can indicate a "lower" signal strength than you actually have and quality will be degraded. That could be what you have as your results may fit this.
Your overall antenna and coax response may give more signal since the frequency changes which might just tip things over the edge. (Antenna gain is not flat over the full frequency range).
If you don't have access to an attenuator to try, one trick that may help is try partially removing the aerial plug so that only the centre pin is making connection. If things improve, too much signal is the most likely cause and you'll need to try an attenuator.

There is a lot of work being done to prepare for future changes to channel allocations, part of the planned changes needed for the introduction of 5G transmissions in the 700MHz+ band. Some of the work is also related to improvements to the DAB sevices and coverage.
If it is suspected that too much signal is a possible problem then checking the reported signal strength on the manual tuning page, without doing a retune, will show just how much is present. Depending on the make and model of the TV, it is usually recommended that the strength should not exceed about 85%.

All this talk about too stronger a signal is a puzzle to me. The manufactures of TV's and set top boxes have no idea where there equipment is going to be installed, either a couple of hundred meters from a powerful transmitter or miles away from one. So why would they not put a limiting circuit in the front end. I used to work in the avionics industry and limiting circuit were used back in 60's when it involved transistors, transformer, chokes, resistors and capacitors. Today it would just be one small micro circuit costing just pence on the scale of manufacture required. Also earlier post talk about "no signal" and "weak signal" messages. I too have had that problem and I solve it by changing from HD to SD. I think HD is a big con unless you have a very large TV. Which? say that you probably won't see any improvement in picture quality until you get to a screen size of 40in and above

Ken Collyer:
Such limiting circuits have never been developed for use in a TV tuner input. Some TV tuner are more sensitive than others and it is simple to fit an attenuator for those with either more sensitive tuners or are closer to the signal source. I have worked in the TV industry for 50 years before retiring and it has always been the case that some need attenuators whilst others do not.
HD signals on COM7 and 8 are generally transmitted at a lower power output that the other multiplexes. Thos on COM4 (the BBC HD services) are generally at the same power output as the SD services. COMs 7&8 are temporary services and are expected to be subsumed into the main multiplexes when the majority of TVs have an DVB-T2 (HD) reception capability.

Ken Collyer: True, they dont know where a TV set might be set up, but as Mike P points out, tuners work fine within reasonable tolerances, and since not all muxes work at the same strength, its much easier to add an attenuator if needed, rather than add yet another component (which has a cost) to a problem that most people dont face.
Switching from HD to SD to solve a simple problem is short changing yourself - HD is certainly much better than SD (something I have to occasionally demonstrate at work to disbelieving customers - Which is most certainly wrong on that score), and its not sustainable long term.
The idea that 40in is a 'large screen' makes me chuckle - the most common size TV sold in my department is 49in, and 55in is almost as popular - we now have 75in sets in store, and the bulk of TV's are not even HD any more, but UHD/4K - so four times the screen resolution of HD. And now there is 8K...

With All due respect, in case you'd forgotten I am a regular contributor on these boards!. I do NOT need telling about all the work going on for the 700Mhz clearance for 5G! In case you missed the point that I was mentioning I said that "virtually EVERY (main and some relay) transmitters have some supposed work at present !" There are not enough engineering teams to be working on every transmitter at the same time which is why I went on to say "I must admit I find that a bit difficult to believe although there are further clearance changes to come over the next 2 years but not at Bluebell Hill AFAIK. "
It should also be noted that 85% is not an absolute limit, it is a guide, it will vary from set/brand to set/brand.
Ken Collyer:
MikeP points out that the HD muxes COMs 7&8 are often transmitted at lower power than the other main muxes. At Bluebell Hill those two muxes are transmitted with 5.012 kiloWatts compared to the main muxes at 20 kiloWatts.
You mentioned your location in a previous post, you also mentioned your aerial is old, I'm sure you don't need telling that any degradation of connections and coax could affect different frequencies across the band slightly differently, so if you are still having problems with "weak signal" that may be the reason. However I also pointed out that it would be worth considering whether you have too much signal if you are close to the transmitter.
If the front ends of receivers are overloaded beyond a certain point (this can vary from brand/set to brand/set) they can indicate a "lower" signal strength than you actually have and quality may be degraded. So it's always worth giving your system a check-out.
I also agree with the points that MikeB makes about HD. As a Which? subscriber myself I have to say that some of the comments on more detailed technical aspects can be a bit ill-informed. Of course you really need a Full HD screen (not HD ready) to fully notice the differences.
