Stafford: There is no reason why the power should have been reduced, but there is a high likelihood that your aerial system has a fault, and therefore its there that you should start to look for the problem.

Sandy Heath transmitter is showing reception problems on just all BBC channels and Horror channel. No other channels ITV, channel Four, film four, sony movies, CBS Drama, etc I recieve are seeing this picture and sound blocking. This intermittent cutting of picture and sound across BBC channels appears ONLY between 6:00pm and 9:00pm (since 31st October). the rest of the day other than 6:00pm to 9:00pm all channels including BBC are okay with NO picture and sound blocking / jumping

My high-gain aerial system and cabling are okay with no faults as otherwise if this was the case then all TV and radio received on my TV would suffer picture cutting but they don't.

Andy Dodds:

There has been Planned Engineering work at Sandy Heath over the last week with "Possible weak signal" which might be the cause of your problems. Cannot confirm if any work continues this week until later today (see Planned engineering works | Freeview ).

Have you actually checked your cables etc.? Problematic connections, water ingress etc. can seem to affect reception of just an INDIVIDUAL, OR several or all multiplexes.

Check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can often be a problem. See what signal strengths and quality you are getting for the multiplexes shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead. Also check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction.

Thanks Chris regarding engineering works to my local transmitter Sandy Heath. But annoying though as I am watching Space 1999 on Horror channel each night. All BBC, 5 select, 4seven and horror are the only ones currently experiencing low signal quality on and off from around 5:00pm to later at night with no other channels affected.

A lot of the Sony channels were moved by Sony back in the summer to Local multiplexes.
See Channel listings | Freeview
If you receive a local multiplex on LCN7 then you should get them.
I did not think that there was a local multiplex transmitted from Sandy Heath but one listing I've seen suggests that there may be a Cambridge one on UHF35. You may/may not be able to receive it at your location as it will be low power compared to the main multiplexes.

From the 10th of November I have lost channels from both freeview & freesat. I use a vu duo 2 to record to. I have checked all connections & the tuner cards in my vu duo 2 but still no better. I use a communal aerial & satellite. My postcode is NN17 1RP. I think it happens every year possibly the weather?

Richard Tong:

I'm afraid I can't help with any satellite issues if it's a communal installation, if it persists you need to be either more specific about what channels have been lost, and posting on a more suitable board which will likely get a response from someone more expert on satellite, or contact the building management to get the issue looked at but check first if other neighbours have the same issue.

As far as Freeview is concerned, oh dear, your postcode is not well served by any one transmitter. You are obviously in a bit of a poor spot from various transmitters.
The Freeview Checker suggests that Waltham is your most likely transmitter ! However that only gives reliable reception from the 3 PSB muxes, no reception from SDN/COM4, also poor for ArqA & B and variable to poor for COMs 7&8, all after a retune event in March next year!
But it also shows consistent reception (albeit it mostly variable) from all muxes except COM8 from Sandy Heath. SDN/COM4 is good at present but becomes variable after a retune on 12th Feb. and after other transmitter changes on Mar.4th. you'll lose COM7.

Having told that tale of woe, as regards the channels you have lost - there've been a few changes since the summer. Sony have moved many of their channels to Local muxes. There is supposedly one at Sandy Heath on C35 but I doubt you're in an area that'll get it. You'll most likely get some/all on Satellite. They've also more recently renamed many of those channels. Last week and today (Thurs) have seen Film4+1, More4+1 & E4+1 move multiplex. See Channel listings | Freeview but at time of posting it doesn't show the E4+1 move.

If it's other channels you are missing, check with your neighbours if they have the same problems and post with details.

Chris.SE: He must think we're psychic. Having to resort to guessing his missing channels is a bit much.

He doesn't even tell us if he's tried a re-scan or a reboot, either.

Anyway, like most who ask for help on here, I don't suppose we'll ever hear from him again.

Simply not worth the time and effort.

Our aerial is on the roof at NN38UT, it is pointed across some trees in the distance. Most times we get a good signal but over the Christmas period 2019 it was a disaster. I wanted to watch "Still Open Open All Hours" on BBC1, it was unwatchable. As I type this it is okay but for how long? Using a signal strength meter from Screwfix I only get LED light. I notice from the Brian Butterworth map published 2004 we are in the edge of the reception are. Is this upto date??? There is a masthead Amp. We did have a Optima filter, Chan21-60, 470-790MHz in the loft, I have removed this just for the moment as we were still getting the problems. I have since learnt it should be between the aerial and the Amp-a job for a man with a ladder. In general it the first 16 channels that are affected. Please help if you can.
