I too have been having trouble with freeview (from Mendip) not adjusting start and end times anymore. Most annoying and frustrating. I have two different top end Humax PVRs and smase has been happening with both.

I have a phone number for you of 01752 663322 but is this right please as I can't raise you?
I have been getting short bursts of no signal o BBC1 latterly and wondered if this was common.
Thank you.

Yes, I've been getting "No Signal" bursts too for some weeks now. I also find the freeview programme guides very slow to load (same on 3 TVs and 2 PVRs. Never used to have these problems.

Clevedon Resident etc:
There are no known faults at the Mendip transmitter. There are two possibilities. One is that there could be a poor connection in your aerial system, so please check all the cables and connection. Unplug all coaxial plugs/sockets and refit to clear any corrosion/oxidation on the contacts.
Another possibility is that you have too much signal;. Please check the signal strengths on all multiplexes (strength and not quality). It shoudl ideally be between 60% and 85%. If it is more then you have too much signal and it needs to be reduced. If it is less then you need a better aerial (preferrably a widband type or a log-periodic) to receive more signal.

Please don't publish other people's contact details on a public forum. It is highly dangerous and unwarranted. Especially if it is done without the express permission of the individual concerned.

There have been a few "bursts" of No Signal over some recent days. As Mendip is not reporting any faults and there is no Planned Engineering this week, I suspect it's the current weather conditions with the high pressure weather system. Patience will be what's required and don't go retuning as you may lose more and tune to incorrect signals or none at all.

I was having problems on the Mendip Transmitter with no start and finish signal when using a series link for Newsnight on BBC2 HD, which caused the end of the programme to be missed.
It is now working correctly.

Weak tv signal problems over the last weak. Tonight, Friday, lost all tv between 6.00 pm and 7 pm. My equipment is set to receive TV direct from the Mendip transmitter which has work trouble free for years. I live in Nailsworth Gloucestershire. I have checked all my equipment and feel fairly confident all is ok. When I check the signal through my Youview Box on BBC I find that quality ican be 100% but signal strength is now always low at best around 27%. I presume tonight strength has dropped well below 27%. No reports of any problems with the Mendip Transmitter so does anyone have any ideas what may be the cause of these recent signal problems.

Some parts of Nailsworth could find reception difficult. Put your postcode details in Digital UK - Coverage checker to give predicted coverage for your location.
As I posted recently current high pressure weather has affected reception periodically.
The very large high pressure weather system is set to continue for a few more days yet and so may well cause reception difficulties at various times.
It would be advised to check all your coax connections (remove and re-insert the internal ones), if you've moved anything about in recent times, flyleads can sometimes become faulty. If your aerial installation is a few years old, water may have got into the aerial connector or the aerial may have moved a bit in the high winds in recent times or your downlead may have become damaged or degraded. Visual inspection is a good idea.
