I use the BlaenPlwyf transmitter but see that it is NOT providing Extended Freeview, given my location and the fact that the terrain and trees prevent me from considering FreeSat what are my options? Also should I pay less for my TV license?

ian: If you'd provided a postcode, the reception guru's could have considered your options.
Its a pain that you can't get Freesat, etc, but frankly, its only due to the PSB channels providing a local transmitter (even if it does have the full channels) that you have any TV at all. The idea of paying less for fewer channels comes up a lot, but its the commercial channels who cant be bothered to pay to broadcast to you, so no, you cant get a reduction.

ian: By law a TV Licence is required to *view* any broadcast channels.
However, the TV Licence goes exclusively to the BBC and, as a Public Service Broadcaster, you have all BBC channels.
It is absurd to raise the question of paying a Public Service Broadcaster less because Commercial operators do not serve you. This is because Public Service Broadcasters have obligations as far as terrestrial coverage goes and the Commercials do not.

ian: As MikeB says, your postcode might give us an idea as to what your options are. On the basis of BlaenPlwyf's COMs being at lower power than the PSBs, in some cases it may be possible to receive the former with an amplifier or perhaps higher gain aerial.

Thanks for your feedback. I was pretty sure i had included PC, perhaps that was a different forum. So her is PC SY233EU. Ian

ian: I'm surprised. A terrain plot shows you can almost see the top the transmitter, were it not for the high ground just over a mile away:
Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location Digital UK suggests that you might be in with a good shot, obstructions such as trees not being the fly in the ointment. Use a TV or box to test to see if the three COM muxes are there (you need one with manual tuning). For each one, select/enter the UHF channel number and wait - do not press the button to scan/add services immediately. Give the thing 10 seconds or so and see what readings for strength and quality you get (in this state the device operates as a poor man's signal meter). The UHF channels are: COM4 - ITV3 etc - C25 COM5 - Pick etc - C22 COM6 - 4music etc - C28 While you're at it, see what you get for PSB1 (BBC SD services) and PSB2 (ITV, S4C, C4, C5 etc) which are on C27 and C24 respectively.

ian : Purely out of curiosity, when you mention Freesat as not being an option for reasons of the terrain / trees etc, have you actually had this vetted as not being possible by a dish installer? or is it an assumption based on your personal opinion?
The only reason I ask, is because there are very few places in the UK where satellite reception is in reality, just not possible, as although a tree or some other obstacle might well be considered as being capable of blocking the signal to a dish, in many cases there are ways around this, as dishes can be mounted on the side of a chimney, on top of a pole, or alternatively on a tripod stand positioned at near to ground level, plus of course the signal hits the dish from above at an elevation of around 23 degrees or so, and not the horizontal direction the dish happens to be facing, which is always lower.
If of course you are located tight on the Northern side of a reasonably high Southern facing hill, then this type of situation is indeed most likely to be a no-go for satellite reception, although a view from above does not suggest that this applies, and the satellite signal plotter does "not" indicate a no-go situation at the location given.

ian : Update on that said. Unfortunately it would appear that a terrain problem does exist, as further checking using an another (and superior) sat signal plotter site indicates that an obstruction does exist in the form of the hill seen to the front of the property in question, the obstruction occurring at just under 50m from said property at a height of 21m.

Geraint Jenkins : Channel 5 was offered the capacity on PSB3 which is now occupied by BBC Three/CBBC, so the likely answer is "not any time soon".
As for BBC Two Wales in high definition, your best bet is to look to the BBC:
Nations HD Channels - BBC - FAQs - Home
It is the case that there is only one variant of BBC One HD on the terrestrial platform. The same applies for BBC Two. I imagine that when the time does come to change this that they are both likely to be done.
