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?

Thanks John. Looks like the engineering work has finished but our signal is still terrible, so it must be the weather causing interference.

We have lost all COM4 channels from rowridge transmitter after a retune. Signal strength reports as 0 on Ch 25. Another box we have not retuned shows the channels properly. All off the same aerial. Any ideas?

There are a few reasons which could give you this issue.
1. the cable or connections to the problem receiver has an issue.
2. the receiver itself has an issue.
3. all of the system has an issue, the reason I give this issue is that all equipment reacts differently to reception, so if your signal is not very good you could have one box that can still handle showing channels with poor reception but another box not showing the channels. I commonly find Sony TV showing channels with a reception so poor that no other brand can display any channels.

Still terrible reception here in Holton Heath. It was fine up until the week the transmitter engineering work (and heatwave) started. Could the weather still be causing this problem?

On turning on the TV this morning at 07:00,I had a very poor signal. This has remained the same all day. When I retune, I get even less channels.
Until today, we have not had any problems. Can anybody assist?

S Wilson.
There are many things that would cause your issues.
1. problem with tv aerial
2. problem with tv cable from aerial
3. problem with distribution unit
4. problem with connections
5. problem with tv tuner
6. too much signal
7. not enough signal
far to many issues to guess which one is your issue without fully testing the system.
Are there more than one tv on the system, and if so do the others have the same issue, if they do then you can take issue 5 off your list.
If you have no other TV's then try a digi box.
Then try a new cable
then try a new aerial
Or just call a local engineer who should do a system test for FREE if they are nice :)

If you system signal is marginal then you will notice issues during hot periods.
You will also have the same effect if you have too much signal.
If your system is outside and 20 years plus in age then you may consider having an upgrade.
If your issues are the same on multiple tvs then the issue will definitely lie with the system.
If the issue is on just one tv then you could look at replacing the cable to that one outlet.
If your system was in tip top condition then you would be less likely to notice issues in the changes of weather :)
The transmitter works may have only be a coincidence and actually the issues could be due to the heat and your system being vulnerable with regards to its signal quality.
The quality of the signal that you are receiving is far more important the strength.

Thanks Jamie. The one thing I didn't mention is that we have a lot of trees in the vicinity.
We have experienced poorer reception in the past due to weather conditions, and possibly trees being in leaf, but never anything as bad as this zero quality on all muxes.
And it went suddenly, just as that engineering work started (and the heatwave), so we assumed it must be that.
Maybe it was just a coincidence and something has gone wrong with our aerial or the cable connecting it to the main TV setup? (The other TVs are fed from this via some sort of distribution system in the loft, as left by the previous owners.)

I live in Ferring West Sussex and about 10 pm every evening for the last couple of weeks stations like Dave, Drama, Pick TV ITV 3 have dropped out. The next morning they seem to come back. Now they have all gone apart from the main channels. I have retuned but they will not come back. I have checked all cabling etc and nothing seems amiss. Has the station stopped transmitting these channels or has power been reduced ?

Power has not been reduced.
Its is more likely that the mux that runs these channels is running marginal and you are now experiencing issues with them.
If your antenna is sited outside it will not last forever, general about 20 years but that does depend on the quality of the materials used.
You should only return your set when there has been changes to the tv channel line up.
If your receiver cannot see a channel when the aerial is not working correctly then all a retune will do is delete it from the tv memory.
Retunes do not fix problems with system reception.
If you are running more than 1 tv maybe try rigging the system to just one tv and see what reception you get.
failing this I would look at changing the antenna or is location.
