Carl Amey: I had a check at the engineering notice board and see that Hannington has now been removed from the list but though with Rowridge now being mentioned, its HD service being off air for 50 minutes this afternoon.
As far as Hanningtons COM6/Ch47 is concerned the power that its presently operating at is the final situation and so nothing will alter on the transmission side of things, that said, if you are the type that can spare 30 minutes or so to experiment with your aerial then the next time your C47 signal takes a dive you might possibly find that the situation could be improved by slight repositioning of the aerial to the left or right of its present mounting position, this of course having to be carried out whilst your TV is left sitting on Ch47's signal check screen to provide instant feedback on the results of your actions.
The other point being, although I do realise that aerials in your area are seen to be facing towards Hannington, but though have you ever tried to receive a signal from Rowridge since it switched over to high powered operation? especially where it involves its vertically polarised 200Kw transmissions, as the terrain indicator shows a clear line of site situation up until a "very" short distance away from where you are located, and even although the signal is shown to be obstructed its not by any means severe when compared to some other situations I know where reception is possible albeit via diffraction, this being signal bending.
To check if reception is possible from Rowridge on the rear of your aerial even although its roughly 10 degrees out, you should try a test by going into your TV or boxes "manual" tuning facility (should it have one!) and enter Rowridges COM6 on mux Ch28 but do NOT press search or scan, as on most devices if its possible to pick up a signal the strength / quality that its being received at will be seen.

We're experiencing picture break-up on BBC channels in the RG20 9DF area. We have two aerials and the performance is the same on both. This seems to be signal strength issue.

Update: INTERFERENCE SOLVED
In response to your suggestion jb38 I have access the manual tuning function and inspected ch28, the strength was very good, but the quality was ~10%, but i did not move our aerial. I suspect moving the aerial may well improve the quality.
As a side, I have now resolved the issue! I hope this will help others... The solution?
HDMI / Coax interference. In summary, I have moved our booster away from the other mains cables and the HDMI leads going in / out of the AV receiver. The HDMI leads have also been moved away from the coax aerial feed which when moved drastically improved the quality of ch47. I replaced the fairly cheap HDMI lead going from the PVR to the AVR with a spare I had (which appeared to be of a better quality, look and feel anyway) and the quality of ch47 shot up to 100%. All other channels are also 100%.
Now, why this affected just one frequency / channel, I have no idea, but the conclusion is that interference can occur between HDMI and Coax circuits. I have done a small amount of digging on line and others have reported similar issues including interference from games consoles vs certain freeview channels or their entire reception. So, in my case it would appear a better quality HDMI lead from the PVR to AVR helped reduce the interference. I hope this makes sense, and I hope it will help others. Thaanks for taking the time to reply jb38.

Paul Nickson - check your cables, HDMI and coax in particular. See my post above.

Carl Amey: Well although I am certainly pleased to see that your Ch47 problem has now been rectified by the changes you have made such as replacing the HDMI cable and generally repositioning the leads, however its still a bit puzzling why the problem you were experiencing had an apparent time factor built into it "if" none of your equipment was being moved around.
Thanks for your report regarding the test on Rowridges Ch28, this actually being quite a good indication when taking into account the fact that you are obtaining this on the rear of an aerial that is positioned around 10 degrees or so out from a true 180 reverse pick up, and so its very likely that the signal quality would greatly improve if at any time the aerial was correctly positioned, although this is really something that is a bit academic anyway now that your reception is back to normal.

No problem. We have tried using Rowridge in the past with little success. The terrain maps offered by this site indicate that the signal is pretty much a no go and the official digital tv sites all suggest Hannington as a priority. I am happy to try other channel tests using our aerial where it is if that help you jb38. Our location here in Southampton is also half way up a hill which is almost the tallest point in the city.
The time of day weirdness surrounding the quality of ch47 is indeed very odd. There was a notable difference in the morning vs the evening. The only difference that was obvious was the temperature outside and in our loft and surrounding our equipment. The lounge is much warmer in the afternoon with the sun beating in.
One other thing to note, we are on the flight path for the airport, but this has never caused any issues with the signal in the 7 years we have lived here.

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.

Hi
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?
Thanks,

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.
