@Briantist: Could you confirm that Arfon is transmitting BBC, BBC1, ITV and S4C channels in HD please? I'm unable to get any of these and I'm not sure why not...
Thanks in advance, Martyn

Martyn: Yes, as above. You must have a Freeview HD (DVB-T2) receiver to see them, of course.

@Briantist. Thank you for the quick reply!
I thought my TV (40" Sony KDL-40BX400) was sorted but, when feeding it directly from a terrestrial aerial, it looks like it's just HD ready.
I'm using a Linux box to feed it now, but the terrestrial card I use (Nova T-500) is only SD. Surprisingly (and very pleasingly) my satellite card (Nova-S, allegedly only DVB-S) picks up HD (DVB-S2) just fine, so I can receive HD from that for the time being.
Looks like I'll have to wait a while until DVB-T2 cards start coming out.
Thanks again, best regards, Martyn

Arfon,is one of those more interesting Transmitter sites.
Origionally a VHF Band 3 TV transmitter,broadcasting ITV, HTV Wales on Channel 10, Horizontal polarization at 10KW.
A relay of Presely at that time.Commission date:9/11/62.
Then on 17/10/75,Arfon also started to Brodcast BBC 1/BBC 2/HTV Wales on channels
51/44/41 respectively,Vertical polarization on UHF.
According to the IBA at the time,this transmitter was broadcasting all TV channels at 3.6Kw,but in the BBC handbook at 3.5Kw. Up until the last listing of analogue Transmitters on the BBC website Arfon was then broadcasting at 4.2Kw?
Then i see your information showing that Arfon's analogue powers as being only 4 Watts!
What's the full story?
If you look at any other UHF Main/relay station,particularly during the UHF analogue era,transmitter powers were uniformed.
I 'cut my teeth'using this Transmitter for domestic installs well down the Cardigan coastline as far as Aberaeron/Tre-saith,where reception of both Blaenplwyf and Preseli was impossible.Ocassionally reception suffered from tidal fading,though mast head Amplifiers largely compensated for any losses.
Arfon also broadcasts Classic FM at 18.75Kw mixed pol and Heart?Cymru at 5Kw mixed pol on Band 2 VHF/FM.DAB:BBC/Digital 1 on Band 3 VHF.

The other interesting aspect of the Arfon TV transmitter is that it is well received on the East coast of Eire particularly in the Dublin and Wicklow areas.At 2Kw,i would imagine that DTT from Arfon is quite robust in these areas.
