Having checked the Digital UK website, there are no engineering works listed for Bluebell Hill treansmitter. That site is the better sources for such information.

Your post code, ME2 4RR, didn't trigger the transmitter details as it requires the space between the two parts.

You need to check that all your aerial cables and connections are in good condition and that all coaxial plugs/sockets are clean by unplugging them and then refitting. That will clear any corrosion/oxidation from the contacts as that is a common cause of the problems you report.

Margaret Hibberd:

It might be worth checking that your neighbours aren't having similar issues just in case there is some unusual local interference problem.
Also, do you have another TV set just to check that it's not your TV having the problem? If not, would you be able to take your TV to a neighbour to check it works on their aerial?

Com7 and Com8 channels are sporadically breaking up to disappearing.
First thing in the morning they exist Early afternoon they have degraded to 0% signal strength
Evening they return.

Signal quality is always low 30% to 50%

Aerial is professionally installed as a distributed network across 90 or so properties in a retirement village.

BBC4 HD and BBC NEWS HD are the key requirement but all channels on COM7 & COM8 are affected.

Then you need to report it to the management of the complex. They are responsible for the aerial system and its maintenance.

MikeP: Thanks but it is clearly not the aerial system here.

Noting comments elsewhere exactly the same problems were being reported as long ago as January by users in the north of the country.

Only Channels 55 and 56 are affected with the COM7 and COM8 multiplexes. Everything else is perfect here.
Noting today that the bit error rate on those channels climbed during the day.

I have changed my cables, inserted a variable attenuator to no effect. You can't attenuate a signal that is already zero

Geoff:

Because it is channels 55 and 56 that are affected shows it is the aerial system at fault, probably still using an aolder aerial that is not suitable for reception of those channels. That is why the Management need to have the system updated to use a wideband aerial.

There was no advice to attenuate your signal, so why try it?

The aerial is wideband and professionally installed distributed system.
Also the fact is that those channel are received ok much of the time, they just degrade at random.
I tried an attenuator after reading a post somewhere about signal strength being too strong and causing tuners to mis-interpret the data being decided. Clearly not the issue and I did not really expect it to have any effect.
Thanks

Geoff:

Please would you check the signal strength reported bu your TV set, it's usually on the Manual tuning option but DO NOT RETUNE, and then report them here. We need to see the strengths for all the multiplexes that are available. Ideally you need them to be between 60% and 85%. Any less will give rise to variable signal loss and any higher is likely to overload the tuner.

I suspect the item your read was refering to a signal overload condition and not the issue you have.

Also note that aerial systems sometimes develop faults and being professionally instal;led does not prevent faults developing, either in the distribution system, the cabling or the connections.

Currently Chanel 55 is registering

Bit error level. 2000
Signal Strength 92
Signal Quality 7. Drops to 3 and 0 and back again

Chanel 56 is registering
Bit error level 1200 to 1317
Signal strength 94
Signal Quality 44

Steady and no break ups at this time - this changes day by day.
Regular signal issue on BBC 4 HD on a Saturday 9pm onwards. For weeks recordings of the dramas at that time have either failed or pixelated. But signal good at other times such as right now.

Geoff:

Putting your postcode in Digital UK - Coverage checker shows you should have adequate signal for COMs 7&8 on C55&56. However, note C55&56 are now used as Single Frequency Networks (SFN) for COMs7&8 and you may be getting interference from the Crystal Palace Transmitter.
I note that there's only a small difference in the bearing for the two transmitters, but you are so very close to Bluebell Hill. To me it suggests that the aerial installed is inadequate - it's not directional enough or hasn't been aligned correctly. In either case you need to do as MikeP has suggested and complain to the complex management. As he's said systems can develop faults, the aerial may have moved or for some reason not been installed correctly.

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.
