John: Dave is carried on COM5 multiplex. Have you replaced your Group A aerial with a Group K or wideband one? Do you receive COM4 (ITV3 etc) and COM6 (Film4 etc)?

I covered the post-switchover signals from Bilsdale not all being on Group A channels here:

mr f reant: The first thing is to ensure that ensure that the TV is tuned to the transmitter to which the aerial faces. In your area, reception may be possible from Winter Hill and Congleton transmitters. The latter carries fewer channels (the Public Service ones).

If your aerial faces Winter Hill, ensure that your TV hasn't tuned to Congleton (for the channels it broadcasts). To do this, check the signal strength screen on BBC One, ITV and BBC One HD (if it has a HD receiver). It should tell you the UHF channel that the signal is being received on and this is equivalent to the frequency.

For BBC One it should be tuned to C50 (706MHz) for Winter Hill rather than C44 (658MHz) for Congleton.

For ITV it should be tuned to C59 (778MHz) for Winter Hill rather than C41 (634MHz) for Congleton.

For BBC One HD it should be tuned to C54 (738MHz) for Winter Hill rather than C47 (682MHz) for Congleton.

You don't need to check others because they will be as one of the above. That is, BBC Two will always be the same as BBC One.

Further advice on your reply.

mr f reant: I would like to add that knowledge of the make and model of your receiver (TV or box) "may" allow me to find the user manual online and so give you more exact instructions on what to do.

Hi,i have two alba tv`s with built in freeview and since April i cant get any bbc channels,i gave tried retuning them but with no luck,both tv`s are on different aerials in the loft and one tv shares a aerial with another tv that can get the bbc channels,freeview version is v.2.9 but there's no option to upgrade it.Any ideas?.

I have just recently moved into a house in Blackwater, unable to get any signal through the aerial fitted on the roof. We have had BT install infinity and we can now watch our main television via a booster but unable to pick up any signal for any of the other tv's even using an indoor digital aerial. Any ideas?

Aerial is on the roof -a lot of channels saying no signal.
No bbc channels for a Month - do I get a discount in the license fee ?
Dave Lindsay
Thursday 16 May 2013 1:58PM
John Curtis: I suggest that the two most likely reason for getting no signal from the rooftop aerial is because either the lead is not connected all the way through and/or because there is an amplifier connected inline which is not powered on.

The amplifier could be on the mast, in which case it requires a separate power supply that connects inline, often behind the television. Or there could be a distribution amplifier perhaps situated in the loft which feeds signals to more than one room.

Judging by the size of the aerials on the rooves of the houses in your area I think it highly unlikely that the signal lower down and indoors is likely to be sufficient for an indoor aerial!

Whilst you are only 31 miles away, you do not have anywhere near line-of-sight. The difficulty is the higher ground on which Camberley sits, which is in the way.

If your aerial points to Crystal Palace, which is roughly east north east, then see if any of your receivers have manual tuning on. Try manually tuning its broadcast (UHF) channels which are 23, 26, 25, 22 and 28.

Steve Cheshire: No. The Licence Fee does not guarantee availability of reception.

From what I can see, your postcode resolves to a block of flats. This makes me think that this aerial you refer to, which is on the roof, is a communal one. If so some then communal aerial systems require adjustment to take account of the new channels.

If, one month on, no resident has bothered to notify the landlord then it isn't likely to get fixed!

I have inbuilt Freeview on my LG32LG5700 TV. I am unable to select another mast/receiver option on this model. Since the last digital update my signal has been poor on ITV channels and BBC even poorer to non-existant on other channels. I hasten to add this is the case with any TV tried in the house. The signal being picked up from my home in Cheshire is now broadcasting in Welsh (received from Wales,10plus miles away), and not from Winter Hill. Without the cost of a new TV aerial (which I believe is a digital one), what are my options please?
Dave Lindsay
Friday 17 May 2013 1:18PM
Jeff Sutcliffe: There is no such thing as a "digital" aerial. An aerial isn't bothered about whether a signal is analogue or digital, but only dependent on frequency of the signal.

The purpose of the automatic tuning scan is to look through all frequencies to 'see' what signals are available. Once completed the receiver must 'decide' which to use as its main ones (the rest being put in the 800s). In this case it has chosen to use the signals from the Moel-y-Parc transmitter in Wales. This in no way indicates that the aerial is not picking up Winter Hill. The poor reception comes about because the signal being received is from a direction other than which the aerial faces.

I downloaded the user manual for your TV here:

http://www.lg.com/uk/support-product/lg-32LG5700

Page 45 of the booklet (page 47 of the PDF) says that you have manual tuning at your disposal.

Run the automatic tuning through without the aerial plugged in. Then manually scan UHF channels 50, 59, 58, 49 and 55, these being the five standard definition channels of Winter Hill.

Many thanks Dave, read one of your posts and done that now already, the BBC still squeaks on an off-it never used to! I have a bigger problem resorting and organising my Median TV channels as manually tuned to your suggested channels but BBC is still also programmed to receive Welsh as channels 001/002 with BBC North in 800's. Not sure why for my postcode in Cheshire the strongest transmitter is suggested by this website as Moel-y-parc? I hope I am not expected to do a manual retune for an update every time.
Dave Lindsay
Friday 17 May 2013 2:31PM
Jeff Sutcliffe: Signals spread out according to the terrain; they aren't delivered by a postal service!

You probably have clear line-of-sight to Moel-y-Parc, or are not far off, but you certainly don't to Winter Hill. See this terrain plot to Winter Hill:


Terrain between ( m a.g.l.) and (antenna m a.g.l.) - Optimising UK DTT Freeview and Radio aerial location

The higher ground on which Halton and the surrounding area sits is in the way. You are very low down and the motorway and trees appear to be in the signal path.

The signal strength screens should allow you to identify which transmitter you are receiving from:

Moel-y-Parc 45, 39, 51, 52, 48.

These numbers relate to BBC One, ITV, ITV3, Pick TV, Film4, respectively (as do those given in my previous posting for Winter Hill).

Thus, if the BBC One you are watching is tuned to C45 then it is being received from Moel-y-Parc. Any poor reception is likely because the aerial is pointing the wrong way for the signal being received.

For those sets without manual tuning you may be able to avoid picking up Moel-y-Parc by having the aerial lead unplugged during its part of the scan; say the first 50%.

Jeff Sutcliffe: If you have a Sky box or another device which puts out an analogue signal onto the aerial system then ensure that it isn't on or near the new Winter Hill channels 49 and 50.

Thanks for the advice Dave I will take a look or boost my already boosted aerial I guess. I have no Sky or similar. I'm sorry I thought the transmitter signal strengths had been adjusted recently, I thought it may have been a transmitter issue.
Dave Lindsay
Friday 17 May 2013 7:43PM
Jeff Sutcliffe: Once you have each set tuned to Winter Hill (having verified the channel numbers shown on the signal strength screens) then don't be tempted to retune. Your sets will give the best picture and retuning won't improve it.

With digital there is strength and quality. Quality is effectively the digits that make up the picture being intact. Strength is the level of the signal.

Amplification makes a signal bigger but cannot improve its quality. See:

Jeff Sutcliffe: In situations such as yours where you don't have line-of-sight, you are relying on refraction. Consequently, in some spots one signal may be good and another not so. It is always possible that C50 (the BBC channel) isn't good where your aerial is, it never having been used before.

Hi, i am interested in 4G signals (at 800MHz). If a transmitter is transmitting channels say at (uhf) channel 30 (which is no where near 800MHz) what factors would lead 4G to cause problems in this situation?
Thanks

Saturday 18 May 2013 12:40AM
Ross Taylor: The problem that 4G can in certain circumstances cause is only one of its transmitter creating a powerful RF signal that's capable of swamping the wideband input of a TV or boxes tuner thereby desensitizing it to receiving TV signals.

Although having expressed my view in the past insomuch that I think the whole issue is being somewhat hyped up, as any powerful RF source that transmits on a frequency near to (not actually on) that used for TV reception is equally capable of desensitizing the RF input circuitry in a tuner, as it causes the tuners AGC (automatic gain circuit) to cut back the sensitivity of the tuner, this in turn also kills the TV signal.

The point to remember being, that any wideband tuner such as used in TV's is always susceptible to sensing RF signals near to its operating range, the tuner doesn't actually require to tuned to the offending signal, and as far as Ch30 is concerned, in my opinion any TV receiving programmes on mux Ch30 is only ever likely to be affected if the 4G transmitter was located at less than 30 metres or so away and was working at maximum power, AND that being coupled to the tuner fitted in the TV or box being one of the more mediocre types usually found in lower end devices.
