Hi. It would have been the weather conditions at the time.
There had been moderate Temperature Inversion/Tropospheric Ducting affecting large parts of the UK for several days, it sometimes accompanies high pressure.
In such conditions, do NOT retune, it will more likely remove your correct tuning. It may even leave you incorrectly tuned to distant transmitters whose signals then disappear as conditions change.
These conditions cleared the UK by Thursday morning.
Despite the incorrect spelling, this link does work - simple technical explanation
https://www.bbc.co.uk/rec….jpg
I would say you were possibly lucky that you didn't have any disruption to your normal multiplexes from Winter Hill.
Essentially it results in interfering signals from other transmitters in the UK or Europe reaching you and so your wanted signals are disrupted, and of course ability to receive signals from transmitters further afield that are on different frequencies. It can/did also affect FM and DAB.
I would guess that with reception of BBC Wiltshire you received one of the transmitters in the south of the UK. Without out looking up the channel numbers, I can't say which one of the top of my head.
It won't necessarily affect all multiplexes or necessarily at the same time if more than one. It can last for seconds, minutes, sometimes hours or longer.
The BBC had a warning on their Works and Warnings page for a few days, and Freeview had added one last Wednesday (better late than never!) but at the time it was then mainly affecting the S & SE.
As an aside, if your aerial is a log-periodic it won't be a group A as most are wideband, some newer ones are tuned/filtered to cut out signals above UHF Channel 48 (essentially Group K).
Does your Sony RDR-870 have a setting to auto-retune if it has no signal or receives new signals? If so, I would turn such a setting off as it can be more trouble that it's worth if your regular multiplexes are affected by interference.

Thanks for the reply Chris,
The Sony does scan for channels in the background and this has been a bit of a nuisance in the past because of picking up North Wales and this causing problems with timer recordings and the PDC (programme delivery system). It was frequent enough to be a problem and prior to the Log Periodic I had a roof mounted wideband Yagi. The log aerial set up has stopped this particular issue. Possibly lower signal levels (loft) have helped as well.
As an aside to that, the Panasonic DMR-EX97 HDD recorder has countless reviews where owners comment on lockups and having to unplug the recorder. Panasonic are aware of the issue but had no fix. I have one of these and it suffered this issue. Since switching to the Log Periodic loft system the issue has vanished confirming my suspicion that the lockups were a result of out of band transmissions causing problems with background channel scans. I noticed the problem was guaranteed to show whenever Freeview changes occurred, but not now.
The recent BBC Wiltshire event caused no apparent problems in use. The Panasonic has not registered anything in the EPG.
The aerial I chose was a Blake BLA-LP28A which is a Ch 21-37 Log Periodic. It is marketed as a Group A with 28 elements.
I deliberately went down that route and sacrificed COM 7 on the basis that it is going to disappear anyway. The Yagi had to go because I had an external chimney removed and in all honesty the loft set up has been truly excellent in everyway. The change from C/D to A for Winter Hill really worked in my favour on this one and going 'loft'.
Thanks again and Merry Christmas.

Hi Karl. Merry Christmas to you.
As soon as I saw mention of your Blake LP28A I realised I'd completely forgotten about that one, haven't seen it mentioned for a while. Blake make some good aerials. Having a loft mounted aerial will certainly drop the signal strengths, so as your wanted signals seem strong enough, it's obviously helped with the unwanted ones.
Your posting error is not an uncommon problem that the site owner has had since some software upgrades, but also posts sometimes take a while to appear, so wait about 5 mins and do a refresh before trying a repost (so ignore the error message).
You are lucky in one way that Winter Hill's main multiplexes are within Group A (UHF channels as mentioned in Winter Hill (Bolton, England) Full Freeview transmitter | free and easy ).
COM7 as you probably know will close by the end of June 2022 so probably no real sacrifice (dont' know what will happen to those channels yet). The one exception for your area is the Preston Local mux on C40, just outside Group A. I don't know how sharp the fall-off in response is on the LP28A, do you get any signal on C40?
Those signals you were getting on C24 & C27 were highly likely to be from the Rowridge transmitter on the Isle of Wight. All those local stations are on BBCA there.
Winter Hill also uses those two channels for the Manchester Local and Manchester GI muxes, but Local muxes are beamed in the direction of the areas they serve.
As you were getting Rowridge at the time, there might have been some quality degradation/increased errors on you PSB muxes. Mendip also uses C32, C34 & C35 for those muxes, they have been received in the Winter Hill region on similar occasion in the past.
If you are interested in Dx, see Sandy Heath (Central Bedfordshire, England) Full Freeview transmitter | free and easy and the posts before it. The sites mentioned are useful (as well as having some links) but also get familiar with your own set's strength and quality/error figures for your muxes. Changes there will also give you a clue about your local conditions.

Hi Chris, yes Ch 40 comes in at a fair signal strength. The aerial set up is the loft mounted Blake feeding a loft situated distribution amp. I went for a low gain Blake twin output one, I think around 4db gain. One feed from that amp feeds the main lounge where there is a three way passive Triax splitter with a feed each to the Sony TV. Sony HDD recorder and the Panasonic recorder.
The Sony recorder shows 52% strength and 100% quality on Ch 40. Other main muxes are around 89 to 85%. Viewing has been 100% glitch free since installing this set up. The original instinct was to go for the biggest Yagi that would fit the loft but considered thought and all I read of the log periodic giving a flat response and immunity to impulse noise (loft... wiring etc) had me settle on the Blake. Well its proved a winner. Each of the three feeds that already see a loss from the three way splitter will still withstand an additional 10db (at least) before things start to get flaky.
I suspect had Winter Hill remained on groups C/D that the loft set up would not have been as successful as I understand that the higher frequencies would suffer much more attenuation through tiles and from trees and so on.
Thanks for the link, I'll have a look at that.

It does sound like your set-up is working very well for you, and you choice of the LP28A was certainly wise.
I have been considering LPs for a while, for similar reasons, flat responses and impulse noise rejection not that I currently have any major issues with my current set-up.
When COM7 closes I shall revisit it so that I'm in a situation where I would be as future proofed as I reasonably could be, you don't know how things could change. Also whilst I'm not expecting any new mobile masts near me, especially on the line-of-sight, you can never be sure. Current masts are behind me and well to my right off the aerial beamwidth.

One possibly practical bit of advice on logs (and based purely on what I see on rooftops) would be that while the log periodic can be an excellent technical solution they also seem problematic to mount really securely as they all seem to be tail mounted. I see so many drooping down, probably due to birds landing on them, and this I understand is bad news because of the way the log is constructed and the position of the internal terminations which are at the front of the boom. Water then collects in the boom and causes issues. I also believe the F connector that they all seem to use at the back of the boom for connection to the outside world is very difficult to get watertight over the long term. Again looking around I see a lot with a large 'loop' of coax going up and over the height of the installed aerial, presumable to stop water making it right down the cable.
It is certainly something to be aware of for an external installation. Get a good rigger you can talk to.
What I also see around here are a few of the really small logs and they look very sturdy indeed. They are tiny, just looking now.... Labgear LPCT at 340mm length. I'm assuming they are successful as I see a few around, and some on bungalows so at a height disadvantage.

Some very practical advice there Karl covering issues that some of us have come across. If you are in a strong signal area, yes those "mini" logs seem ok but I haven't installed one personally. I'm not sure the length (from the CPC site?) is correct, Labgear quote it as 445mm. Blake also do a 22-element (mini) log either Group K or Group T both 450mm long and slightly better gain. If anyone needs one now and can get COM7 then Group T is needed, otherwise go for the Group K. Blake seem to have addressed the weather-proofing of the F-connector issue, but there's always belt and braces with use of a bit of silicon sealant or self-amalgamating tape.

Forgot to add as a general buying guide, watch what and where you buy, don't go just by description, look for spec. - I've seen some aerials described as High Gain that are definitely NOT "high" gain, watch postage as well as unit costs.
