Stuart O.: No. What I'm saying is that in February 2009 Mynydd Emroch changed from being a relay of Carmel to a relay of Kilvey Hill.

The final stage of Mynydd Emroch's switchover therefore occurred on 9th September (as it was then a relay of Kilvey Hill and had been so for seven months).

As for Machynlleth and Ynys Pennal, they are relays of Long Mountain and, according to the list of analogue transmitters from Ofcom, were so before:

UK Television Reception Advice

The Digital UK trade newsletter for the Long Mountain switchover sheds some light on this:….pdf

It says that "Before switchover, Long Mountain is technically a relay of Blaenplwyf but at switchover, it becomes line-fed."

So pre-DSO Machynlleth and Ynys Pennal were relays of Blaenplwyf via Long Mountain.

I don't know why some relays are re-attributed from one main transmitter to another; it is a good question and perhaps one of the professionals on here can shed some light on this.

I can appreciate that where such changes mean different regional programming that it might not go down so well! On the other hand, some might be pleased to watch what they see as regional news of more relevance to them.

My reason for thinking that Machynlleth and Ynys Pennal were relays of Long Mountain rather than Blaenplwyf is that they are shown in the same colour as Blaenplwyf and its relays on the Digital UK Transmitter Networks page shown here:….jpg

Had they got that map a bit more correct, Machynlleth and Ynys Pennal would be shown in pink, the same colour as Long Mountain and all its other relays, not black, the colour of Blaenplwyf and its 7 relays.
The same goes for Penrhyn-Coch and Trefilan that I had missed out which should also be pink on the map, not black. (LL115FQ)

Stuart O.: That map you gave a link to dates from June 2009 and is authored by Ofcom and not Digital UK.

Sam Coombes: If you cannot receive satellite and you cannot receive reliable terrestrial, then I suppose that the only medium left is the internet.

However, the first thing is to check that your receiver is tuned to the transmitter to which the aerial faces. Also, it may be that the transmitter only carries PSB channels, or that it carries COMs, but that they are likely not to be reliable at your location.

For a full list of Freeview services, see:

DTG :: DTT Services by Multiplex

This lists services by multiplex (PSB/COM).

If your transmitter is PSB-only, is it only COMs that are unreliable? If this is the case then the question must be one of can you get a reliable service from the other, full-service, transmitter? If not then you'll only get the PSBs.

Knowledge of your location in the form of postcode may allow a more accurate answer. I have been general because I have no idea which applies due to not knowing your location.

Sam Coombes: It's a picturesque part of the world you live in. However, based on predictions, it doesn't look good for TV reception. That said, predictors are in no way perfect and in locations such as yours, what can and what can't be picked up can vary over a short distance.

It may be worth consulting with an aerial installer with a view to either using a different transmitter, or a different aerial that may pull in the COMs.

I looked on Streetview and spotted aerials pointing roughly west, some vertical and some horizontal, the latter being slightly clockwise of the former. I can't work out where they are pointing, but where ever it is, you may be lucky to get the COMs.

I can't suggest any services that will stream TV over the internet. Maybe others on here can, or maybe look-up other forums that specialise in internet/broadband services.

Again thanks dave for your help I am going to invest in a xb16a aerial and looking up and down the street the only other aerial that resembles such is a few doors up and they don't seem to have any reception issues so I think I'll give it a whirl and fingers crossed it may resolve it thanks again for your support
