The symbol shows the location of the Bluebell Hill (Medway, England) transmitter which serves 200,000 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.

Which companies have run the Channel 3 services in the Bluebell Hill transmitter area
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

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.
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.
