The symbol shows the location of the Ridge Hill (County of Herefordshire, England) transmitter which serves 270,000 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.

Are there any planned engineering works or unexpected transmitter faults on the Ridge Hill (County of Herefordshire, England) mast?

I've not yet done the further tests or made any changes, Chris, but today's update is that the wind has now dropped completely and C25 is back to its full glory of Strength 100%, Quality 90% and ITV 4 is therefore fully restored.

C29, the alternative ITV1 mux, is now at Strength 100%, Quality 30% which is where it normally is unless the wind is blowing. At this Quality level it is unwatchable as is usually the case.

C24, which I'm not so bothered about, is now at Strength 90%, as usual, but Quality is absolutely zero and does not register at all even when watching it for 30 minutes.

My tentative conclusion is that the very tall conifer a 100m from my house, when stationary because there is no wind, totally blocks C24 such that absolutely no signal is received by my aerial which is a high gain one on a high pole above my chimney stack. When the tree is swaying, some signal on C24 manages to get past it although, on average, it is always unwatchable.

When the tree is stationary, C25 is received satisfactorily but when it is swaying in the breeze it blocks the C25 signal intermittently such that the average signal is unwatchable and worse than its alternate, C29.

However, the converse is true with C29. When the tree is stable the C29 signal is blocked such that it is unwatchable but when the tree is swaying then the average signal strength goes up such that C29 actually becomes more watchable than C25.

The above does suggest that the actually channel transmitters on the Ridge Hill antenna are physically located in different places on the structure and that their positions/heights relative to the line of sight of the tree are causing the differences. Either that or it is something more complex related to different frequencies, albeit ones that are very close together, being affected very differently by either still or swaying branches and leaves.

Does any of this make any sense?

Richard Sutton:
Sorry to drop in - I've just been reading your comments regarding channel 29. I think you will find that channel 29 is no longer transmitted from Ridge Hill - I suspect you are picking a signal up from the Malvern tx which has mux SDN on channel 29.
According to the Freeview channel checker Ridge Hill transmits
Ch 28 BBCA
Ch 25 D3&4
Ch 22+ BBCB
Ch 21+ SDN
Ch 24 ARQA
Ch 27 ARQB
Hope this helps

Graham Seward:

Thanks Graham. In that case, I'll stop worrying about C29.

I've just checked again as there's still no wind and C24, which I should receive, is still zero quality and C25, which I need is now down to 60% quality but still watchable.

I've had these problems ever since I bought this house. I've tried different aerials and tried Sutton Coldfield but it has always been impossible to receive the all channels I'm supposed to receive.

I visited a TV retailer in 1998 which was in the Evesham town centre to buy a TV when we moved here in 1998 and all the display TV's were showing DVD content. There was a sign above the TVs which said something like "None of our TVs are able to show live TV content as there is no TV signal in this area". At the time I thought this must be nonsense, but 25 years of experience have shown me otherwise.

Richard Sutton:

As mentioned before C29 IS transmitting. I personally don't have an aerial pointing at Ridge Hill at the moment, I may see what I can do over the weekend BUT it was received in Worcester on 21/04/2023 at 01:31:12 and as has been said before only ITV1 (West) is on the multiplex. The Freeview Channel Checker will not include C29 if someone's location is not predicted to receive it!
I have already explained how to check your C29 multiplex on your LG. Please do so.

Quote "When the tree is stationary, C25 is received satisfactorily but when it is swaying in the breeze it blocks the C25 signal intermittently such that the average signal is unwatchable and worse than its alternate, C29.

However, the converse is true with C29. When the tree is stable the C29 signal is blocked such that it is unwatchable but when the tree is swaying then the average signal strength goes up such that C29 actually becomes more watchable than C25."

I've explained about the tests required without the amp/splitter in place and how to tune your TV correctly to get all the TV channels in the correct LCNs. Please do these tests, they are far more important than any speculation/guesswork about trees, the weather, co-channel interference or anything else!
Whilst trees can have an effect, this assumption is pure guesswork at present and whilst the effects of trees CAN be frequency dependent, that fact that you are seeing no effect of the other UHF channels leads me to conclude that the trees are unlikely to be the PRIMARY issue.
The main multiplexes on virtually all main transmitters are usually on the same antenna, however it is likely that C29 is on separate antenna beamed appropriately.
Whilst Malvern is co-channel on C29 with SDN, it is Vertical polarisation and very low power, it's possible that signals might occasionally have some effect on Ridge Hill C29, it's likely to be very small, and in any event is not your main region, just an added bonus if you are interested in the West Region News.

Richard Sutton: Just to confirm Chris' info, digitalbitrate.com monitor Ridge Hill's PSB2(West) mux from their scanner in Worcester (see link below) which indicates it is broadcast on 538MHz (UHF channel 29) using QPSK modulation and carries ITV1 as it's only video stream (the remaining 5-6Mbps of capacity that isn't used for associated audio/data is packed out with null packets).

I will do the tests you have suggested over the weekend, Chris.

I don't really know what the significance is, if any, but on my LG TV the listing which appears below the signal test graphic still says:

555 Accessible TV Guide
800 ITV1
802 ITVBe
803 E4+1
