s savage: Digital UK's engineering works page says Mendip (and thus its relays) may be liable to interruption.

You should not retune, just wait for the channels to come back.

I live at BS14 0UE and since late Friday 24 May 2013 I have lost all BBC, ITV and SKY channels. I have retuned numerous times but only receive 34 DTV stations and 3 radio stations on UHF Channel 54. I have several TVs running off an amplifier situated by a loft aerial and all are affected. Is there a problem with the transmitter or is it at my end.
Many Thanks, Dave

David Branfield: There are no known issues with the Mendip transmitter.

Try bypassing your amplifier by connecting the aerial directly on to one of the TV feeds.

Thanks Dave, I tried to connect directly but was having some difficulty. However, by unplugging the cables I must have cleared the problem as now I have full channels restored. Thanks for your quick response, much appreciated, Dave

Hi,
I live at BS3 2SX and for the last 2 weeks or so have problems with BBC1, BBC2 & BBC3. All other channels appear to be fine, but BBC has intermittent, blurry picture. I've retuned etc. and all channels come back - yet BBC channels never get any better. My TV has in-built freeview rather than operating from a freeview box.
What's the best way around this?
Thanks.

Hi, I live on BS3 3PG and bought a new tv recently with built in Freeview.
The TV that was in the lounge used to struggle with some freeview channels, but is now in the conservatory and works perfectly - the new tv however is not picking up any channels at all!

So initially I spoke to a customer advisor at LG, who told me to boost the signal (which didn't work) then I spoke to a lady at from the Digital UK site and she said that our signal would be too strong if anything & advised me to buy a Variable Attenuator.

So that just arrived, (though it had no instructions) and I'm still stuck. Do I literally need to repeatedly auto tune changing the dial in tiny increments to find a signal? Or is there a simpler way?

Also, I've plugged a small tv aerial lead into the attenuator thing, and then have a longer cable running to the aerial point in the wall - is that correct?

Sorry, I'm not overly competent with electrical stuff!

Thanks - K

Ms K: There are a number of possibilities which must really be worked through one at a time.

First and foremost, ensure that the TV is tuned to the correct transmitter - that is to the transmitter which the aerial faces and not a different one. Don't assume that the automatic tuning function will see you right, particularly as there are at least two transmitters that may be picked up. Information on this is at the end of this message.

At your location, Ilchester Crescent and Mendip are on roughly the same bearing. Ilchester Crescent's signals are vertically polarised, hence aerials for it are vertical (elements up/down). Mendip is slightly anti-clockwise of Ilchester Crescent and aerials are horizontal (elements flat).

I looked on Streetview and there is a mixture of the two transmitters being used on your road.

Number 10 has two aerials both which are vertically polarised, but the reflector (the bit at the rear) on the top one is incorrectly fitted as it is horizontal. Also, what is presumably the aerial lead emerges from behind the drainpipe and is probably trapped in the window which is likely to be doing neither the cable nor the window mechanism any good. All these things could be impacting on the TV signals received.


I suggest that you put the attenuator to one side and look at whether the TV is tuned correctly first. Once it is tuned correctly then nothing positive will be achieved by tuning it again - it gives the best picture it can based on the signal that is being fed into it. In such circumstances then your attention must turn elsewhere as to a solution.

Is there one aerial feeding both points or are there two aerials?

If there are two aerials and they both face the same transmitter (i.e. both horizontal [Mendip] or both vertical [Ilchester Crescent]) or there is a single aerial then start in the conservatory. Check that the TV now in the conservatory is tuned correctly. Having done this tune in the new lounge TV by connecting it to the aerial feed in the conservatory. Check that it too is tuned correctly. Once you have both sets tuned correctly leave the tuning alone as any poor reception has its cause elsewhere.

The long lead you mention (or indeed any lead) must be swapped with another, such as the one from the conservatory, to discount it as a possible cause, but ideally only after the TV is tuned correctly.

-----

There are six Freeview signals, each of which carries multiple services, a "service" being BBC One, BBC Two etc. There are five for standard definition and one for high definition.

Bring the signal strength screen up on the following five services (six if it's a HD set) and observe the UHF channel number tuned:

BBC One | IC=C41 | M=C49
ITV | IC=C44 | M=C54
BBC One HD | IC=C47 | M=C58
ITV3 | IC=C42 | M=C48
Pick TV | IC=C45 | M=C56
Film4 | IC=C39 | M=C52

I've abbreviated the transmitter names to "IC" for Ilchester Crescent and "M" for Mendip. If the TV doesn't give the UHF channel number but instead only gives a frequency in MHz then let me know and I will give you the equivalent MHz frequency for each.

If your aerial faces Mendip you may find that Ilchester Crescent is tuned, particularly as its channels are lower and therefore picked up first during the scan.

You may be able to avoid the unwanted one by having the aerial unplugged during part of the scan, but if you provide more information then more accurate advice on achieving that can be offered.

Is this mast going to transmit the extra Hd channels in the future? If not i may pay for my arial to be turned around. (51.4127,-2.6071)

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
