Ste Byrne:

If you look at the posts above yours you will see that engineering work is being done on that transmitter and has been on-going for a few days. They never indicate when the work will finish as it depends on weather and any unexpected problems the engineers may find.

Having already updated our freeview equipment to receive certain HD channels from the Llanddonna transmitter, we have now been informed that as Llanddonna is not an extended Freeview HD (COM7 and COM8), we have now lost some channels that we watched regularly. This seems unfair and discriminatory to the population it serves. At present the only way around this is to install Freesat equipment which will incur further costs! Is there a possibility of this transmitter being upgraded or are we to remain in the dark ages?

Reception on all BBC channels very poor from Llandonna on 22 August 2016.

Tried retuning Freeview several times but only getting Quality 1 on BBC 1, 2, 4, Red Button and Radio. In fact of all BBC associated channels none are registering above 1.

Why?

All other channels are showing Quality 10, even the Channel 4 stuff which usually suffers more than anything.

Brian Springthorpe: If all the other muxes are fine (and don't look at just quality, you need to be looking at signal strength, which should be around 75%), that points to a problem with your aerial system. Just because a wire might be frayed or damaged, doesn't always mean that the strongest signal will be the one that gets through - wires do weird things. For a start, change the aerial lead - cheap, easy and if it was duff, an easy fix. If the problem remains, then you need to look further up the signal path.

But if your getting a very high signal strength (which is why a postcode is so useful), then the BBC channels might be the ones to go crazy - they are likely to be the strongest. So check out the page called 'too much of a good thing'.

Brian Springthorpe: Reception in many parts of the UK is presently being affected by a series of high pressure zones sweeping across the country, the effects of said pressure being most likely reason for the reception problems referred to, unfortunately nothing can be done to help rectify the problem except to wait until the situation improves.

I presume you mean 'poor reception'. To be able to offer any advice we need a full post code so that we can examine the reception conditions at your location.

Postcode LL777UR, last couple of days CCTV on channel 260 (a data channel) is only giving a test card with the number 15048 and the time. Is the CCTV channel no longer being broadcast from Llandona or is there a problem with the transmission?

Why is PBS not available from Llandonna. Their website says it should be available as Channel 94.

william perry: PBS America is broadcast on the COM8 multiplex which is not broadcast from Llanddona. COM8 (along with COM7) is a temporary service which is broadcast from 30 main transmitters covering around 75% of UK households and will close some time between 2020 and 2022.
