Carl Amey: Thanks for the update, all points noted, but with regards to interference being radiated from the HDMI cable and which seemingly only affected Ch47, although this type of thing is not entirely unheard of but on the extremely odd occasion that it is its usually more associated with an oxidised or corroded connection on an aerial feed where specific frequency RF signals are involved and not broad spectrum digital interference such as radiated from an HDMI lead and which can affect a number of mux channels.

I feel that unless you have recently made any alterations to the positioning of the cables on the rear of your equipment I suspect that the interference caused by the HDMI lead has most likely pre-existed, but was not noticed because simply it did not have any effect on reception due to the RF signals carried in the coax being at a high enough level to keep this potential interference problem at bay, therefore the only reason I can see for this situation changing is that the level / quality (especially the later) of the signal being received on Ch47 is not constant and is inclined to taper off at certain times within a period of 24hrs (ref your time factor observations) thereby allowing the pre-existing HDMI interference to take hold, this then giving the impression that the interference is targeting Ch47 when in reality its purely a consequence of a slightly lower signal level being received.

I would like to emphasise though that I am not referring to any massive differences in levels, but just enough to allow the HDMI interference to enter the equation.

As far as a further signal test is concerned, I would be interested to know what level Rowridges BBC (Ch24) is being received at considering its radiated from the top of the mast, unlike the mux channel I had previously requested a check on

By the way the terrain indicator I was referring to is seen on the undermentioned links.

I have been having continuous issues with my Freeview signal over past 10 days with varying severity affecting picture and sound, and affecting all channels.

My postcode is RG1 3JJ with my a communal aerial. I have retuned and replaced the coax cable.

A fault on Hannington transmitter was reported last week, and possibly this week, although mixed information from various websites.

Any ideas of how to improve signal, when an expected resolution for transmitter issues might be, or who to report fault to, or if there is another underlying problem e.g 4G etc?

Fran: An engineering notice with regards to Hannington and possible interruptions to service over the next week is seen to immediately precede your posting, albeit that it was posted on the Aug 27th.

However, it would have been prudent to have made one or two local checks (neighbour etc) before having updated anything on your installation, as others will likely be experiencing the same difficulties as yourself.

If your system has been working OK prior to the problem mentioned, then I would be inclined to bide my time and see if the situation improves.

Thanks jb38, I did see that post, but also on top of same page it says:
The BBC and Digital UK report there are no faults or engineering work on the Hannington (Hampshire, England) transmitter
and the radio & TV investigation service website and digital UK Meridian website also say no faults or engineering this week. Hence the comment about mixed information.

Was hoping someone might have some other source or reliable information. Or where else to try.

I guess I will just wait it out and suffer another week of no TV and further raid the dvd collection.

Fran: Well I have to admit to being somewhat suspicious of that message myself, as after I had drawn your attention to it I couldn't find it listed in UK Free via twitter access listings, a facility I use for checking replies to postings when out and about, the RT investigation site good as it might be not always being bang up to date with events.

However that aside, as far as 4G is concerned I don't really feel this comes into the equation as far as your location is concerned, as in any areas where it might possibly have the potential to cause problems the transmitters that serve the area are operating on channels in the latter part of the 50's whereas the highest channel number used by Hannington is 47.

I really do feel that rather than making any attempts to improve your signal other than what you have already done, your best policy by far would be to make one or two local enquiries (at least one of outside of your housing complex) to determine if others are also experiencing similar difficulties, as this is the correct faulting procedure to use by anyone connected into a communal aerial system as it gives a far better idea of the situation that exists, this then enabling advice to be given appropriate to that situation.

Anyone know whats going on at Hannington - I am experiencing ongoing dreadful reception problems. Have checked aerial and nothing changed at my end. All channels seem affected, and BBC1 & 2 etc always used to be reliably strong now rubbish. This seems to vary acc. to the time of day. Early morning worst , evenings better. All HD channels always unuseable. I am 9 miles from transmitter, south east. (Hook). I have masthead amp. setup, and 2 x tv's both of which suffering. SIgnal strength at TV is 30 to 50% and fluctuating down wildly, and signal quality has very high error rate (using TV diagnostics). Result is no picture or complete pixellation in the mornings , partial intermittent pixellation in the eve's

Briantist: Yes - I have seen the 'no problems reported' entries on websites but the fact is that nothing has changed at home, EXCEPT the fact that both my TV's now having problems with signal strength and quality. Can it be a coincidence that these problems started right around the time that maintenance occurred. Transmitter engineering

As an adjunct to my post above, and given that I am not imaginiong the problem, how does one report it in order that it can be investigated?

Bruce: I think your missing the point about Brian's advice, and there is no point in reporting the 'problem', because the problem is within your own system, not the transmitter.

We have seen a lagre number of reception problems similar to yours, which have arisen after engineering/retuning and upgrades at various transmitters, and this is almost certainly due to an increase in power from the transmitter, overloading the tuners in peoples equipment (there are at least three examples in the past two days).

That is not a problem that can be dealt with by the transmitter - they are transmitting at the power they should be.

Your 18km from Hannington, and so you should be getting a powerful signal, but its now just too much for your tuners. Your masthead amp is really no longer required, although switching it off without cutting off your signal totally requires someone cleverer than me! Follow the advice on the link Brianist supplied, and hopefully your reception should be fine.

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.
