stuart smith: Whereabouts are you in ?

Did you have before ? If so, did you get all the ? If you were missing channels, which ones?

Did you have your replaced with a aerial?

Are you using a communal aerial system such as in a block of flats?

formerly used C/D channels (top third of the band) for analogue. is the lowest which makes it Group B (middle third). Consequently some C/D aerials may not function too well whilst others will. If you have a C/D aerial in a poor reception area, then it might need to be replaced.

Contract aerials are the cheapest and C/Ds can have poor below their intended frequencies.

If you answer the above questions it might to home in on whether this is the problem.

Hi Dave , O/k on SDN working on ch48 till the 27th ...too weak. But BBCB on 47 ,not a thing .
My LG TV is only a year old so it should do HD. If i take a look on c7 analog i see no change in the noise like i can on the other digi . Niether is it on from my local TX i have spoken to every one i know with a hd TV but no one can get it .

Ian Foord: I put the post code BN22 0EP into the BBC website (www.bbc.co.uk/reception) and selected the options to say I had a problem with reception of TV.

Understandably there are notifications about the in the early hours of Wednesday.

However, shows "from 16:19 on 13 Jun". reports "No problems".

So whether it is off-air or not, BBC Reception doesn't seem to say.

Thanks Dave, we'll try the -bypass tomorrow. Whatever happens, I guess we'll just have to wait and see what the 27th brings.

morning,

I live in Valence - we take from (about 20-25 miles away but in direct line of sight from the ridge here). We have a 'main' television with feeding off a rooftop via a - the freeview is still fine following the . We also have two other TVs taking a signal via an aerial in the , again through a booster. Upto a couple of weeks ago reception was perfect then BBC1 and 2 started to drop out (maybe around the 30th May - not sure if that's relevant?) and then on switchover day we lost pretty much everything...retuned but reception is too poor on nearly all (except for the likes of QVC, which is just tremendous...). Can anyone advise whether this is a case of waiting for the 27th before things pick up again please, or might there be something more going on? Thanks for any advice.

Dave H: The fact that you can get QVC but that others are poor suggests that the being fed into your TV is too high and overwhelming the tuner.

For a list of and multiplexes, see here (those with a bullet in the "E" England column):

DMOL Post-DSO Multiplex Channel Allocations

COM4 remains on low until 27th June when there will be another retune. All the rest are up to their final power.

The should be removed from the -top . If an aerial with line of sight for 22 miles to a at 20kW won't feed a single TV without any amplification, then there's something wrong. I suggest that it is unnecessary to have such a setup now.

If the booster connected to the aerial also acts as a splitter (it has two outputs), then it probably needs turning down. You may find that it can be removed and replaced with an unpowered splitter. Indeed, you "may" even be able to run all three from the same aerial with an unpowered splitter.

See ukfree.tv - independent free digital TV advice

See the website of Aerials and TV in for lots of information as well as an online shop:

Television Aerial Boosters / Amplifiers, Splitters, Diplexers & Triplexers

If you choose to run all off one aerial, then you could leave the other as a reserve. If the from the roof-top aerial were to run into the loft, then you could easily swap them (the feed to the main TV would obviously need routing from the loft).

It's best to use threaded F-connectors where connections are generally perminant, such as in lofts, instead of using coax plugs.

With F-connectors you can then swap aerials using a small spanner (although you could use coax connectors if that's what's on your distribution amp).

Obviously you may find that having completed these changes, you are unable to receive COM4.

signal strength is about getting somewhere between upper and lower thresholds. So long as you are above the lower threshold for a to resolve a , then the picture will be as good as it will ever be, providing that is excellent. If you go above the upper threshold then you are potentially overloading your tuner with too much signal.

This is why I say that the booster on the roof-top aerial can be removed as doing so wouldn't impact on the picture, unless it put it below the lower threshold, and as I say, at 22 miles if it does then there's something wrong.

Dave H: One further thing. It's always worth checking that a has tuned to the desired and that you aren't looking at the of another transmitter.

For they are:

PSB1=
PSB2=
PSB3= (HD mux)
COM4= (to move to on 27th June)
COM5=
COM6=

The information at the top of this page which says that COM4 is now on C42+ at 20kW is incorrect.

Check the signal strength screen whilst on one service on each of these multiplexes. The first one on each are BBC One, ITV1, BBC One HD, ITV3, Pick TV and Yesterday. (Refer to the DMOL page of multiplexes I gave you.).

Dave - many thanks for your very detailed ...I'll check that we're tuning to the right for (although I'm pretty sure we are) then remove the boosters and see how we get on. Thanks again.
