CB10 2TL- Saffron Walden, Essex. Same as above- 6.30am today no channels from PSB1 and PSB2. PSB2 returned about 6.50 and PSB1 intermittent. Looks like a transmitter issue?

Neil: Hi Neil. Your transmitter would appear to be Sandy Heath in Bedfordshire. There are no faults or engineering works associated with this transmitter this morning, however, you may experience temporary disruption to your TV signal today due to high pressure. We advise that you do not retune - reception will return to normal once this weather system passes, Richard, Norwich, courtesy of Digital UK, 11:30 a.m.

Neil, Finemess and Dot:
I concur with Richard that your problems are due to current natural atmospheric conditions. Do *not* retune your TV equipment else you are likely to lose channels.
When the weather system currently over parts of the UK passes, your reception will return to normal.

Mr C Veasey:
We need an indication of your location, preferably by giving a full post code of where you live (or that of a very nearby shop, public building or post office) so that reception conditions lacal to you can be checked.

I live in Peterborough (PE3 7EJ)
My reception to the Com5 (ArqA) freeview channels have had patchy reception for the last month
e.g. approx 5 seconds of picture then no reception at all for the next half-minute
other channels have occasionally had glitchy pictures and shortly after the problem started I also lost com4 for a few days but that came back COM5 seems to be my main problem
Please can you tell me if you have any ideas what may be causing the problem? is it atmospherics or could it be something else?
I had not installed anything new which could cause such interference but live in a middle floor flat and don't know about the people above and below

John King: Sandy Heath seems to be fine, and its certainly not atmospherics - if it was, I'd be hit as well.
Start with the basics - whats the signal strength like? And what sort of aerial are you using? If your starting to lose a mux, see if that is unusually low strength wise. It could be all the muxes are less than great, but we dont notice until one goes. If thats the case, then trace back the signal from the TV. A classic is the fly lead at the back - is it lose or damaged? Its a cheap and easy hit to replace it, and if you've still got a problem, then you can discount it.
Could be the aerial itself - everything degrades, and it could be that it needs replacement.
If the strength is very high, then that blanking out can also occur, because its overloading the tuner. If its too much, thats an easy fix.
And then there is interfrence from elsewhere - a dodgy thermostat, a cordless phones charger, etc. Might be next door, and their equipmnet - some time back it was reported by someone that there was interference from a next door neighbours Virgin box. Does it happen at any particular time, etc?
Again, changing the fly lead for something with better shielding can help - you might not be able to stop the rain, but you can get an umbrella. But hopefully you can track down the problem.

John King: If as appearances might suggest, your reception is via a communal aerial system? then its essential to ascertain if other residents in the apartment block are also experiencing similar problems with reception before altering anything, if though they aren't, then by all means carry out checks as suggested by MikeB.

thank you.
It is a communal ariel - which only the housing association owning the building have access to.
I did report a problem to them when this started 4 weeks ago but that was in response to it getting a lot worse and losing all reception for a couple of days (the ariel seems to get a problem and lose all reception every month or 2 - which seems unusual to me)
I don't really know the neighbours, some don't stay that long, many use satelite
(I did try changing the fly lead though didn't use any shielded)

John King: Hi, John. Your Housing Association has the obligation to ensure that you have access to public service broadcasting. It is responsible for ensuring that the communal aerial system is working effectively, although I would imagine that it subcontracts the work out to a local aerial contractor, in the same way that Broadland Housing Association does here in Norwich, where I live. We are fortunate that I have a personal relationship wit the managing director of our communal aerial subcontractor and so he goes out of his way to ensure I don't experience any reception problems. Don't forget that Housing Associations have official complaints procedures that you can follow if you are dissatisfied with any of the services which you pay for in your service charge. Richard, Norwich.
