The symbol shows the location of the Rowridge (Isle Of Wight, England) transmitter which serves 620,000 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 Rowridge (Isle Of Wight, England) mast?

I saw this too, suddenly this morning BBC News HD and the various other channels that I have lost due to having a group A aerial for Rowridge.
But now the wedding is over, they've all gone again. Was this just for the wedding?
I've got the aerial people (via Freeview complaints) coming on 9/6. I was going to stand them down but no such luck.

I understand your point, but I doubt whether this is the case here. I suspect that the definition of "Signal Strength" varies between different TVs - 100% of what? BER is probably a better comparative measure.
On PSB1, 2 and 3, my TV reports a signal strength of ~98% but 0 BER. So I interpret that as a good quality signal and no more. I don't have a masthead amp and we are in a fringe area and so I doubt whether 98% signal strength means anything more than that. If I was seeing the same signal strength but a BER >0 then over-modulation may be taking place - but I have never seen that.
COM7 and COM8 are showing a BER of typically ~500 but with the high pressure this has gone up to ~1500 and last night both went over the 2K mark (and fell off the digital cliff). So all is not wonderful. Ch31 and Ch37 were more stable than this and I suspect that the higher frequency is to blame - and possibly Hannington.
The main point of my original post is that suddenly COM7 was there when it was not last week. Now it is showing "signal strength" and BER similar to COM8. So what changed?

You miss the point. Too much signal being fed into the tuner caues it to fail, hence you get reports of zero signal or weak signal. Supplying 98% will definitely detrimentally affect how your TV tuner works. So you need to reduce it to below a reported 85%.
The only thing that changed is the weather patterns in the area. There has been no change to the transmitter.

Although the Transmitter maps were very useful, they are now appear to be much out of date and I would enquire if these are to be brought up to date to reflect current position. For example,
On the Rowridge data, UHF Channel 37 includes CBS America (TV94) which I used to be able to receive prior to the latest shakeup, but it is no longer there and I have no idea as to where it has gone. I cannot get any response from CBS America themselves. Even an auto tune fails to find it.

Norman Langridge: PBS America (not CBS) is broadcast on the COM8 multiplex which has moved to UHF channel 56 at Rowridge. If you cannot restore this and any other missing channels by manual tuning then you are most likely using a Group A aerial which is not designed to receive the higher part of the UHF band. If you don't have satellite or cable you may be eligible to have a replacement wideband aerial fitted free of charge, which can be arranged by contacting the Freeview Advice Line (see link below).

BBC programs on 106 & 107 (HD) & others on COM7 are unavailable in parts of Southampton & Chandlers Ford since the change over. I have had a new aerial fitted by Freeview but no change. The broadcast power is just not enough. Why should we loose our TV just for the sake of 5G phones? When is it going to be rectified?
Can a TV be connected to Freeview and FreeSat at the same time?

Depends on the TV. If it has both a Freeview UHF tuner and a separate satellite tuner then it can. My main TV has both tuners and is set to allow use of Freeview and Freesat. Note that you will need a satellite dish configured to receive the signals from the 28.2/28,5 degrees East satellite orbital position. It must *not* have an LNB designed for use with Sky Q as that does not receive the Freesat signals.
If you already have Sky (but not Sky Q) then if the LNB has at least three outputs you can use one to connect to the TV's satellite input (a screw type called and 'F' connector).

Sorry, I'm not convinced.
I have a 6db attenuator which I have put inline with the TV aerial in order to test out your point. That is enough to drop the reported signal strength on channel 21 (PSB3) from 96% to 92% (but still a reported 0 BER). On the other hand, COM7 (ch55) and COM8 (ch56) are behaving themselves this afternoon and without the attenuator are reporting 90% signal strength with a BER of around 500.
As soon as I put in the attenuator, channels 55 and 56 are completely trashed. Signal strength zero and 2000 BER - and this while PSB3 reports only a 4% drop.
I can only conclude that the reporting of 96% on a high power mux is not the same as 90% on a low power mux and reducing the signal strength is not going to help matters. Perhaps swinging the aerial round to point to Hannington might improve matters - but then there are trees and a hill in the way.

Then you need to get a local aerial contractor in to look at your aerial system. They will have local knowledge that is not available to us contributors who are remote from your location (I'm in West Wiltshire).

I live to the east of Southampton and have an aerial engineer attending to sort out my issues on behalf of Freeview on 9/6. My signal is already marginal so I'm intending to ask them to fit a group E aerial to suppliment my group A and use a diplexer. I dont want to compromise on a wide band as I believe it will not pull in as good a signal as I get now for the group A channels.
This web page explains the procedure if anyone is interested.

I will report back how it goes....
