Nick : We DO use PAL rather than NTSC which is used in USA. An RGB signal keeps the three colours separate and gives a better quality picture, rather than the 3 colour signals all being rolled together: other people on here will give you a MUCH better explanation as to the difference, though!
If your CRT accepts RGB signals (depends on how old it is) it is still worth changing the Sky setting : you should notice an improvement. "Suck it and see" is generally my motto!

Thanks Dale. My crt actually gives a clearer picture using the aerial connections and putting the tv on a vacant channel. I think that is because however you change the picture settings on the tv and Sky, the picture is a bit smaller than via scart, don't know why. Do you have any comments on that? Best wishes.
crt is widescreen, via aerial sockets, picture still fills screen

Dear Brian,
Is Sudbury broadcasting any hd channel? Can't see it in the list at the top of this page, nor does anything come up when I tune in my box, even when I receive some channels from every mux.
Kind regards,
Nick

i am using windows 7 media center and have been able to tune into Freeview for many many years alebit some channels of a weaker strength. i recently bought a Freeview HD tuner for PC but i am still unable to see the HD channels. i accept that my area is not offically Freeview enabled but i'm surprised that the Freeview SD channels are readily available but Freeview HD is not.
any ideas?

Nick: HD services start at switchover, apart from the few transmitters providing an early, temporary, HD service. These are large population centres where the HD signal could be crammed in, usually at lower power than the other multiplexes. The temporary service is replaced by the permanent service at switchover.
Early HD services are available from:
Lichfield, for Birmingham
Crystal Palace, for London
Black Hill, for Central Scotland
Pontop Pike, for Newcastle
Emley Moor, for Leeds
Winter Hill (for Manchester and the north-west) gained HD services at switchover, as have all transmitters which switched over from March 2010 onwards. Those that switched over before this were gradually upgraded between March and November last year.
No more early HD services are planned. HD services from Sudbury, and its relays, will start on 20 July, a little over a month away.

Are there any maps available showing what the predicted coverage will be from the Sudbury transmitter after DSO?

Lisa: The map at the top of the page is the coverage area for the Sudbury transmitter. Note that until mid 2012 the COM muxes will radiate at reduced power, so coverage will be less than that shown until full power is available. If you pop your postcode into the Digital UK postcode checker, (tick the trade box) you can see how reception on each mux will vary over the next year.

Dear KMJ,
You have thrown a spanner in the works. So from next month we will not have 75kw as promised at the top of this page, and we may still struggle to receive?

I also thought that there would be a significant power increase at DSO on 20th July?
