What the buggery bollocks is going on? I retuned my two tellies one upstairs and other downstairs. Upstairs one is totally fine yet the one downstairs is slightly grainy and some of the channels are in the 800s I live along the coast near Margate and we get our signal from Dover which is in the middle of the switch over (next re tune for us is 27th) just wondered why its a grainy picture downstairs?

There is "no signal" on Ch1 and Ch2 which is for BBC1 and BBC2 but they are pefectly fine on the 800 channels.

Confused!

Multiple transmitter reception? You might need to do a manual retune if your TV can't manage it automatically. I assume a "first time installation" or equivalant has been done which wipes the previous channels and starts from scratch?

Freeview pictures shouldn't be grainy - analogue TV can be grainy, but I've not heard of grainy digital TV before. Is it fed from a set top box to the TV, or does the TV have digital inbuilt?

By the way, Margate and Dover operate as a single frequency network for digital services, beginning today with BBC-A - so you could be getting your signals from either or a mixture of both.

If the picture is grainy (as opposed to blocky/breaking up) then it's probably an issue with the connection between the box and the television. If you've got a SCART cable, check that it is inserted properly - cheaper cables won't be as good and are more liable to interference, so try moving it away from other cables. It could also be that your TV is sending the analogue TV that is now static down the SCART cable's other leads, and if it's a cheap one this will "bleed" into the feed from the box and cause the static to be shown faintly on the Freeview picture. So try swapping SCART outputs if your TV has more than one (many only send the analogue picture down one SCART socket), or changing cables to a less cheap one, preferably with individually-screened cables (unfortunately it's hard to tell without opening them up, and even some expensive ones are pretty poor). Another option would be to cut off the relevant pins from the SCART cable so the TV can't send anything down, though I can't remember offhand which ones those are.

As for the 800 channels, what is most likely is that you are receiving signals from more than one transmitter, and it's assuming the weaker transmitter (which it probably finds first) is the main one so puts your actual transmitter's channels in the 800s. You can use manual tuning to get around this; if you enter your postcode into http://digitaluk.co.uk and tick "I am in the aerial installation trade", you can then copy down the UHF channel numbers for your main transmitter and enter these into the manual tuning menu after deleting existing channels, or doing a factory reset and leaving the aerial unplugged for initial setup.

I note they've changed the wording to "detailed view" instead of "I am in the aerial installation trade"...

Oh, they have as well!

Also just noticed that I would be better off on Rowridge VP according to this... hmm... might give that a try at some point in the future.

We do have the old TV lead into the back of the freeview box to one of the connectors so that we could get a picture on analogue when the picture used to break up on freeview before switch over, so perhaps if I take that out and just leave the normal aerial in the back of the box it should work fine. Our TV's are SD ones, downstairs is a 20 inch Daewoo TV/Video combi and my upstairs one is a Bush 32 inch and that one is totally fine. I think when I get the chance I shall manually re tune

[Funk You]

Ahh seems since I took the old lead out the back that we used to get analogue the picture is back to crystal quality. This was never a problem before and it must be the static from the now defunct analogue signal. I'll see how this all pans out regarding the 800 channels too.

They've only changed it on some pages. The following link to another route in still has "I am in the aerial instalation page".
http://www.digitaluk.co.uk/postcodec...x/dummy/NA/yes

The web site's own mini-version of DSO1 and DSO2 with a phased switch over to the new wording?

Irrelevant as they are both a SFN.

You should have some 800s (BBC TV and Radio stations) and analogue BBC One South East, itv1 Meridian and C4 from now until the 27 June DSO2 in any case, Funk. BBC One analogue is on 56 from Dover Now, and BBCA on 50, with the duplicated channels on 58.

I'm finishing the retuning of all Channels 0-99 on the analogue tuner to 69 and using the skip function come 27 June! A first time instalation (not find new channels) on 27 June will say goodbye to the 800s here in Ashford, also on the Dover Transmitter.

PS I do have some RF modulated equipment ( I know!) so i'll tune <Button Press 0> on the Telly to receive to the RFoutput by those pieces when I need them.

I am in Gillingham, and have had similar problems after retuning the main TV yesterday. We get our pictures from Bluebell Hill. BBC 1 and 2, News 24 , Parliament are all blocky and breaking up when I looked this morning.

Will have to have a look at the 800s tonight.

Is it correct that the signal is strengthened after the 27 June when final switchover occurs?

At the mo' you will be getting channels from
46 24 27 42 39 45: the latter has the duplicated TV and Radio Channels
BBC One analogue on 40, itv1 on 43, C4 on 65:

Do try the aerial test on page 284 on BBC One and itv1 and C4 if you still have an analogue tuner to receive Ceefax and anaolgue teleltext and read here

Yes, there is a power up on 27 June too! When the retune comes, you'll find the SD Muxes on 46 43 for the PSBs and
for the the COMs: 45 39 54 with the new HD mux on 40

Yes had a look in all the 800s.

I have channels listed from 800 to 878 including 4 of each BBC station.

Found my good BBC1,2, 3, 4, News 24, CBBC, and CBeebies listed between 831 to 837, so I managed to swap them to the right places.

Let's hope it's all tidied up from the 27th!

[Funk You]

All the channels seem to run fine despite being all over the place on the 800s and so far the picture has not glitched once yet! so its looking good. Hurry up 27th so all this stuff is over

[zoepaulpenny]

WE RECEIVE ALL OUR CHANNELS FROM blue bell hill transmitter in Kent..
all pictures are fine.. cannot find any extra channels though.

[albertd]

I suspect that those with multiple duplicates may not have done a full "New Installation" retune, but some kind of "Find New Channels" retune. At DSO (both stages) the former is almost essential.

A manual retune should only be required if it can be proved that multiple transmitter reception is involved and I have not seen that this has been confirmed in this thread, so far.

Note, though, that duplicates of certain BBC channels (BBC4/CBBC and most BBC radio - but not BBC 1&2) is perfectly normal between DSO1 and DSO2.

I neglected to say that this applies only to the main transmitters which were already transmitting digital TV before DSO1, not to the relays which have only had analogue until now.

I've gone back and am tuned on 0-3 to AV, BBC One, itv1, C4 so as to keep in touch for Ceefax and Teletext page 284.

Spot on: I did a reset on both my PVR and STB.

In Birmingham, the Panasonic DVD/VCR at a home in Edgbaston started picking up the unwanted relay before the main transmitter at DSO so did need manually tuning ...
