The symbol shows the location of the Sutton Coldfield (Birmingham, England) transmitter which serves 1,870,000 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 Sutton Coldfield (Birmingham, England) mast?

Thanks chris -
Yes I've moved everything and the cables are far away as possible from each other.
I've even tried changing the HDMI cables but since I get the same on both boxes
(They arent together) I dont see that can be the issue.
I dont know if the neighbours would know how to check for that C26 signal but I can ask.
(Theyre not too friendly round here sadly) It's still there and rock solid whatever it is.
One chap did say there was a CB or radio aerial sticking up 12 foot higher than
his house fairly near-by maybe thats worth looking at somehow. I will look for it. (But they
dont transmit TV do they?)
I have noticed its fairly stable at 60-61% in the mornings around 10 am - then by the afternoon when
I check again its bouncing down well into the mid 25% and up to about 52% signal and zero Q later and in the evenings.
Its got worse if anything these last couple of weeks regardless of weather - except when
the rain and wind is very bad I do see some improvement for some reason. That seems odd
on its own.
Essentially all the channels are useless on just that one frequency. Even the other low
power channels are clean without any breakups.
I think I'll just have to put up with it. Why it should suddenly start happening is no doubt
part of the puzzle but I'm at a loss for ideas now.
So thanks for your kind input Chris - it looks like no HD movies this christmas.

Hi jack. the fact that you have periods where things are stable, and then times when the signal is "bouncing around" does suggest the possibility of some sort of interference. There could be the possibility of engineering work not currently listed, giving weaker reception at times, but only time will tell on that one.
So looking at the potential interference issues.
Whatever is giving this strange C26 signal if you don't have any channels in the 800's on it, could have other interfering frequencies affecting COM7.
Obviously it could be external, but one needs to eliminate anything internal.
You've looked at the HDMI issue, so trying to eliminate other possibilities is next.
Your pre-amp may have developed a fault and/or become unstable for some reason (or there could be external sources upsetting it).
That model has a VHF input. From what you've posted, there's nothing to suggest you are using it and nothing is connected to it. It's probably not bandwidth limited at lower frequencies as it'll probably have a simple low pass filter, in a similar way to the UHF input having a simple high pass filter.
To check that VHF input isn't getting some external signal causing a problem, a simple check might be to insert a short circuited plug into it and see if it has any effect.
You did post figures where the signals were stable when the aerial went direct to the TV (remember to power down the amp as well if you check again), so that could be another check.
It may be that the amp is exacerbating an issue from some external signal, so this is where an accurate comparison of neighbours' signals would help - do they just have reception problems that are there all the time or do they follow the same pattern as yours?
As far as external sources go, it seems to be something that only operates in the afternoon/evening?
Is there anything local that may use machinary or "discharge" lighting - sodium, metal halide, fluorescent (including compact fluorescent), but also some LED lighting can be troublesome.
CB/Amateur radio interference could be a possibility. They don't transmit in TV frequencies but faulty equipment or problems with antenna connections can produce harmonics or other spurious frequencies that could interfere, and/or especially if those signals are very strong (high power) and close by.
This is a possibility if other other possibilities have been eliminated (we'll come back to that one if it remains a possibility - there are ways of getting it investigated in local enquiries don't work).
One other suggestion, do you have a decent Broadband connection? You could stream stuff/films?

Hi
Just an update
I thought I'd mention I had occasion to re-tune last night and noticed
that mysterious C26 entry has vanished. I did discover it IS freeview format and West Midlands
region sourced. The signal was the SD picture type but no channels were listed.
Very odd.
COM7 is still all over the place. Nothing suggested or I've tried makes it reliable.
I'm seeing signals of 80-83% on all others now (amplified) except the local one
COM7 is still bouncing 63-68 power and random total dropouts on all
the receivers. Removing the amp or shorting the VHS doesnt fix it but thanks
for the straw to clutch Chris.
PS
I will stream TV/movies the same day I get my brain replaced by a cabbage.
Nobody seems to think or care about long term consequences. Sad really.

Hi jack. Thanks for the update. Now that's interesting about C26. There's those unfortunate "tropo" weather conditions around again with the high pressure (although it's predicted to be mostly clear Sunday a.m. but returning Sunday p.m.) so I'm suspecting C26 has been "wiped-out" by interference from another transmitter signal on C26. When the normally received signal and interfering signal get to a certain point, they appear to be just noise to the set - ie. no signal.
I still suspect that your previously received C26 was PSB1 from the Wrekin, especially if you eventually identified it as Freeview West Midlands.
COM7 is pretty much always the most vulnerable mux being lower power and an SFN when you aren't ideally sited. Your trees wont' be helping.

No freeview reception on any channels currently 1530hrs today. Was missing quite a few channels this morning but main ones still broadcasting, nothing now though.

Paul Heywood:
Your intermittent and current loss is most likely due to current weather conditions. Unfortunately temperature inversion/tropospheric ducting is accompanying the high pressure weather system causing signals from distant transmitters in Europe or the UK to affect reception of wanted signals. COM7 can be more vulnerable than some multiplexes due to operating as an SFN and at lower power than most of the other multiplexes, but it is very much depends on location. Freeview and the BBC have current warning about potential intermittent disruption to reception.
Do NOT retune, when correctly tuned, all this is likely to do is clear your current tuning if no signal is found at that time.
To compound matters there is Planned Engineering currently listed for Sutton Coldfield which may affect signals.

Is there some reason talkingpictures (TV channel 82 on mux channel 39) is not transmitting any
CRID's ?
This appears to be causing severe issues with my recievers.
