Edinburgh digital

What a waste of time. Edinburgh did it's second switchover today and I lost
about a dozen channels, and not an HD channel in sight. I'd rather go back
to the old system. Being totally non-technical about it makes it difficult.

If you provide details of what steps you have taken to perform a full
retune/rescan and difficulties encountered together with your postcode
I am sure the experts here will do their best to assist. I have found
them to be a helpful bunch of people.

Well, Craigkelly did. Parts of Edinburgh are on Black Hill, which changes
next week. If you're in Edinburgh your aerial will point north for
Craigkelly, West for Black Hill. Which way is yours pointing?

and I lost about a dozen channels

Which ones?

Specifically, which of the following do you have:

BBC1
BBC4
STV
ITV3
Dave
Yesterday

and not an HD channel in sight.

Do you have a Freeview HD receiver?

In fact I lost 23 channels - used to get 56, now get 33. I think the vision
on most of the channels that I do get is sharper as from today, although it
may be wishful thinking. BBC2 and BBC Alba have the best reception.

The TV is tuned to a BT Vision box and the free to air aerial feeds into the
Vision box, and an HDMI cable attaches the TV to the BT box. Re-tuning is
done from and controlled by the Vision box, not the TV itself. I would
think that if the TV was directly tuned into the available channels, then
the Vision box would become a waste of time. The secret appears to be
having enough cables and ensuring that they all go into the correct slots.
I'm not sure if just the HDMI cable is enough. Just to complicate matters,
I have a DVD player/recorder, but I'd happily disconnect it if it meant
getting the extra channels. I know the HD works properly because HD
programs that I download from BT through their Vision box are of superb
quality, as are pre-recorded DVDs.

You must excuse me - I really am a novice at this, and I appreciate that
there are people in this forum who can advise me.

The BT Vision Box only has a DVB-t tuner and not a DVB-t2 tuner
which is required to receive the multiplex PSB-3 carrying the
HD stations.

Unless you upgrade your digital converter box to one with a DVB-t2 tuner
(and MPEG-4 decoder) you will never be able to receive stations
broadcast in HD.

The aerial points north. I lost channels like Create & Craft, Price Drop
TV and other similar ones. I didn't watch them when I had them, so it
doesn't worry me now. I have lost others that I will miss, like Pick TV,
Dave, Dave deja vu and Sky News. I still have all the channels you mention
below, in standard format. The BT vision box allegedly has an inbuilt HD
receiver, but maybe I should call them to confirm. The TV is an HD model -
I watch pre-recorded HD programs on it.

Firstly, as JG Miller has just posted, the BT Vision box has no HD tuner, it
will not, and cannot receive HD material via your aerial.

The muxes that the channels you mention above, have actually moved to higher
frequencies than they were previously on, although their output power has also
increased, the net result could well be a reduction in signal for these.

How old is the aerial ? More than 10-12 years ? If so, it will probably not
properly receive half the muxes it needs too (therefore half the channels will
be missing).

A clue to this, is did you ever receive Five on analogue ? If not, then that
also points to the aerial being unsuitable. Five analogue used to be on a
similar frequency to your missing channels.

If you have BBC 2 and BBC Alba, you *will* have all the other SD (normal) BBC
channels. Likewise if you have STV, you *will* have C4 and Five. All the BBC
channels are on the same mux, it is impossible to only receive some but not
others on the same mux. STV, C4 and Five all share a mux, so again you can't
have one without the others.

My guess is your aerial might require updating. Can you send a picture of it
to Flikr ?

Unlike analogue, a better digital signal does not result in a sharper
picture. If the signal is not good enough, the picture will break up
in a very obvious way, typically with little rectangles of colour.
Until that happens, the picture is as good as it can be.

I have a BT Vision+ box . It does not receive HD = (High Definition) TV;

It has twin standard definition SD tuners, though you can download HD
material.

it has got a built in HD = (Hard Drive) recorder which may be where the
confusion lies.

Have you carried out a rescan which is...

Settings / TV Settings / Add Channels to TV Guide?

While you are in there check that "Automatic Freeview Channel Updates"
is set to on.
